Table 3.7 Channel A & B RS232 Configured Pin Descriptions 3.6.2 FT2233HP/FT2232HP pins used in an FT245 Style Synchronous FIFO Interface The FT2233HP/FT2232HP only channel A can be configured as a FT245 style synchronous FIFO interface. When configured in this mode, the pins used and the descriptions of the signals are shown in Table 3.8. To enter this mode the external EEPROM must be set to make port A 245 mode. A software command (Set Bit Mode option) is then sent by the application to the FTDI driver to tell the chip to enter single channel synchronous FIFO mode. In this mode the ‘B’ channel is not available as all resources have been switched onto channel A. In this mode, data is written or read on the rising edge of the CLKOUT.

This bus is normally input unless OE# is low. When high, do not read data from the FIFO. When low, there is data available in the FIFO which can be read by driving RD# low. When in synchronous mode, data is transferred on every clock that RXF# and RD# are both low. Note that the OE# pin must be driven low at least 1 clock period before asserting RD# low. When high, do not write data into the FIFO. When low, data can be written into the FIFO by driving WR# low. When in synchronous mode, data is transferred on every clock that TXE# and WR# are both low. Enables the current FIFO data byte to be driven onto D0...D7 when RD# goes low. The next FIFO data byte (if available) is fetched from the receive FIFO buffer each CLKOUT cycle until RD# goes high. Enables the data byte on the D0...D7 pins to be written into the transmit FIFO buffer when WR# is low. The next FIFO data byte is written to the transmit FIFO buffer each CLKOUT cycle until WR# goes high. 60 MHz Clock driven from the chip. All signals should be synchronized to this clock. Output enable when low to drive data onto D0-7. This should be driven low at least 1 clock period before driving RD# low to allow for data buffer turn-around. The Send Immediate / WakeUp signal combines two functions on a single pin. If USB is in suspend mode (PWREN# = 1) and remote wakeup is enabled in the EEPROM, strobing this pin low will cause the device to request a resume on the USB Bus. Normally, this can be used to wake up the Host PC. During normal operation (PWREN# = 0), if this pin is strobed low any data in the device TX buffer will be sent out over USB on the next Bulk-IN request from the drivers regardless of the pending packet size.

When configured in this mode, the pins used and the descriptions of the signals are shown in Table 3.9. To enter this mode the external EEPROM must be set to make port A or B or both 245 mode.

When low, there is data available in the FIFO which can be read by driving RD# low. When RD# goes high again RXF# will always go high and only become low again if there is another byte to read. During reset this signal pin is tri-state, but pulled up to VCCIO via an internal 200kΩ resistor. When high, do not write data into the FIFO. When low, data can be written into the FIFO by strobing WR# high, then low. During reset this signal pin is tri-state, but pulled up to VCCIO via an internal 200kΩ resistor. Enables the current FIFO data byte to be driven onto D0...D7 when RD# goes low. Fetches the next FIFO data byte (if available) from the receive FIFO buffer when RD# goes high. Writes the data byte on the D0...D7 pins into the transmit FIFO buffer when WR# goes from high to low. The Send Immediate / WakeUp signal combines two functions on a single pin. If USB is in suspend mode (PWREN# = 1) and remote wakeup is enabled in the EEPROM, strobing this pin low will cause the device to request a resume on the USB Bus. Normally, this can be used to wake up the Host PC. It should be pulled up to high level before strobing low. During normal operation (PWREN# = 0), if this pin is strobed low any data in the device TX buffer will be sent out over USB on the next BulkIN request from the drivers regardless of the pending packet size. This can be used to optimize USB transfer speed for some applications. Tie this pin to VCCIO if not used.

Bit-bang mode is a special FTDI FT2233HP/FT2232HP device mode that changes the 8 IO lines on either (or both) channels into an 8 bit bi-directional data bus. There are two types of bit-bang modes: synchronous and asynchronous. When configured in any bit-bang mode, the pins used and the descriptions of the signals are shown in Table 3.10.

Each MPSSE can be independently configured to a number of industry standard serial interface protocols such as JTAG, I2C or SPI, or it can be used to implement a proprietary bus protocol. For example, it is possible to use one of the FT2233HP/FT2232HP’s channels (e.g. channel A) to connect to an SRAM configurable FPGA such as supplied by Altera or Xilinx. The FPGA device would normally be unconfigured (i.e. have no defined function) at power-up. Application software on the PC could use the MPSSE to download configuration data to the FPGA over USB. This data would define the hardware function on power up. The other MPSSE channel (e.g. channel B) would be available for another serial interface function. Alternatively each MPSSE can be used to control a number of GPIO pins. When configured in this mode, the pins used and the descriptions of the signals are shown in Table 3.13.

It has the capability of being configured in a variety of industry standard serial interfaces. The FT2233HP/FT2232HP have two independent configurable interfaces. Both interfaces can be configured as UART, bit-bang mode or JTAG, SPI, I2C mode, using the MPSSE, with independent baud rate generators.. The FT2233HP has two Type-C/PD ports (FT2233HPQ and FT2233HPL only), with PD1 port supporting both power sink and source roles, and PD2 port works as a power sink port. Both PD ports support 5V3A, 9V3A, 12V3A, 15V3A and 20V3A PDO profiles, and these profiles are configurable through the external EEPROM at power-up or reset. PD1 port share the same Type-C connector with USB data, and PD2 port is power port only without USB data. 4.1 Key Features USB Type-C/PD Controller. The FT2233HP has 2 USB Type-C and PD port controllers (FT2233HPQ and FT2233HPL only), one port is with the legacy USB 2.0 port to form USB PD port, and the other port is standalone PD port it is used to connect to PD power source. Power Delivery function is designed to meet PD2.0/3.0 specification. USB High Speed to Dual Interface. The FT2233HP/FT2232HP are a USB 2.0 High Speed (480Mbits/s) to dual independent flexible/configurable serial interfaces. This function is backward compatible to FT2232H. Functional Integration. The FT2233HP/FT2232HP integrate a USB protocol engine which controls the physical Universal Transceiver Macrocell Interface (UTMI) and handles all aspects of the USB 2.0 High Speed interface. The FT2233HP includes an integrated +1.2V Low Drop-Out (LDO) regulator and 12MHz to 480MHz PLL. It also includes 2kbytes Tx and Rx data buffers per channel. The FT2233HP effectively integrates the entire USB protocol on a chip. MPSSE. Multi-Purpose Synchronous Serial Engines (MPSSE), capable of speeds up to 30 Mbits/s, provides flexible synchronous interface configurations. Data Transfer Rate. The FT2233HP/FT2232HP support a data transfer rate up to 12 Mbit/s when configured as an RS232/RS422/RS485 UART interface. Please note the FT2233HP/FT2232HP do not support the baud rates of 7 Mbaud 9 Mbaud, 10 Mbaud and 11 Mbaud. Latency Timer. This is really a feature of the driver and is used to as a timeout to flush short packets of data back to the PC. The default is 16ms, but it can be altered between 2ms and 255ms. At 2ms latency you get a packet transfer on every high speed micro frame. Lower values may reduce latency but may also increase USB bandwidth usage and reduce efficiency. 4.2 Functional Block Descriptions Type-C/PD PHY and Controller. The FT2233HP has two Type-C/PD ports. Each port has Type-C/PD required Physical Layer (PHY) and controllers. PD1 port has built-in VCONN switches supporting up to 100mW VCONN power (FT2233HPQ and FT2233HPL only). PD Policy Engine. The PD policy engine is a 32bit RISC processor with 8kB data RAM and 48kB ROM. It manages both PD port 1 and port 2(FT2233HPQ and FT2233HPL only). Default PD configurations are stored in the ROM code. PD1 port can act as power sink or source role, supporting both normal power role swap protocols. PD2 port acts as power sink, which can be connected to a PD charger. By using an external EEPROM, it is possible to change the PD configuration based on specific use cases, such as port 1 sink, port 1 sink/source or PD charge through from port 2 to port 1. PDO voltage/current profiles can also be customised using EEPROM. I2C Slave Interface. The application can also choose to control the PD policy by external MCU through I2C interface. In this case the built-in PD policy engine is halted. The external MCU has full control to the two PD controller registers (FT2233HPQ and FT2233HPL only) through I2C access. An interrupt signal is also provided, so that an interrupt to an external MCU could be asserted when a PD event occurs.

The GPIO block provides up to 8 GPIO pins which can be used as power switch controls based on the PD policy and profiles. Dual Multi-Purpose UART/MPSSE Controllers. The FT2233HP/FT2232HP have two independent UART/MPSSE Controllers. These blocks control the UART data or control the Bit-Bang mode if selected by the FT_SetBitMode command. Both can be used independently of each other and the remaining UART channels. Using this, the device can be configured under software command to have 1 MPSSE + 1 UARTS (each UART can be set to Bit Bang mode to gain extra I/O if required). USB Protocol Engine and FIFO control. The USB Protocol Engine controls and manages the interface between the UTMI PHY and the FIFOs of the chip. It also handles power management and the USB protocol specification. Dual Port FIFO TX Buffer (2Kbytes per channel). Data from the Host PC is stored in these buffers to be used by the Multi-purpose UART/FIFO controllers. This is controlled by the USB Protocol Engine and FIFO control block. Dual Port FIFO RX Buffer (2Kbytes per channel). Data from the Multi-purpose UART/FIFO controllers is stored in these blocks to be sent back to the Host PC when requested. This is controlled by the USB Protocol Engine and FIFO control block. RESET Generator - The integrated Reset Generator Cell provides a reliable power-on reset to the device internal circuitry at power up. The RESET# input pin allows an external device to reset the FT2233HP/FT2232HP. RESET# should be tied to VCCIO (+3.3v) if not being used. Independent Baud Rate Generators - The Baud Rate Generators provide an x16 or an x10 clock input to the UART’s from a 120MHz reference clock and consist of a 14 bit pre-scaler and 4 register bits which provide fine tuning of the baud rate (used to divide by a number plus a fraction). This determines the Baud Rate of the UART which is programmable from 183 baud to 12 million baud. The FT2233HP/FT2232HP do not support the baud rates of 7 Mbaud 9 Mbaud, 10 Mbaud and 11 Mbaud. See FTDI application note AN_120 for more details. LDO Regulator. The +1.2V LDO regulator generates the +1.2 volts for the core and the USB transceiver cell. Its input (VREGIN) must be connected to a +3.3V external power source. It is also recommended to add an external filtering capacitor to the VREGIN. There is no direct connection from the +1.2V output (VREGOUT) and the internal functions of the FT2233HP/FT2232HP. The PCB must be routed to connect VREGOUT to VCORE, the pins that require the +1.2V including VREGIN. This output should not be used to power other circuits apart from VCORE. USB HS PHY. The Universal Transceiver Macrocell Interface (UTMI) physical interface cell. This block handles the Full speed / High Speed SERDES (serialise – de-serialise) function for the USB TX/RX data. It also provides the clocks for the rest of the chip. A 12 MHz crystal should be connected to the OSCI and OSCO pins. A 12K Ohm resistor should be connected between REF and GND on the PCB. EEPROM Interface. EEPROM is optional. When used without an external EEPROM the FT2233HP/FT2232HP default to a dual USB to an asynchronous serial port device with default profiles on 2 Type-C/PD ports (FT2233HPQ and FT2233HPL only). Adding an external 93LC66 EEPROM allows customization of USB VID, PID, Serial Number, Product Description Strings and Power Descriptor value of the FT2233HP/FT2232HP for OEM applications, as well as PD port configurations and power profiles. Other parameters controlled by the EEPROM include Remote Wake Up, Soft Pull Down on Power-Off and I/O pin drive strength. The EEPROM must have a 16 bit wide configuration such as a Microchip 93LC66B or equivalent capable of a 1Mbit/s clock rate at VCC = 3.0V to 3.6V. The EEPROM is programmable in-circuit over USB using a utility program called FT_PROG available from FTDI’s web site - www.ftdichip.com. This allows a blank EEPROM device to be soldered onto the PCB and programmed as part of the manufacturing and test process. If no EEPROM is connected (or the EEPROM is blank), the FT2233HP/FT2232HP will default to serial ports. The device uses its built-in default VID (0403), PID (6040), Product Description and Power Descriptor Value. In this case, the device will not have a serial number as part of the USB descriptor.

The following examples illustrate how to configure the FT2233HP/FT2232HP with an RS232, RS422 or RS485 interfaces. The FT2233HP/FT2232HP can be configured as a mixture of these interfaces. 4.3.1 RS232 Configuration Figure 4.1 Single RS232 Configurations Figure 4.2 illustrates how the FT2233HP/FT2232HP channel A can be configured with an RS232 UART interface. This can be repeated for channels B to provide a quad RS232, but has been omitted for clarity.

The FT2233HP/FT2232HP can have all 2 channels connected as RS422. Figure 4.3 Dual RS422 Configurations In this case both channel A and channel B are configured as UART operating at TTL levels and a level converter device (full duplex RS422 transceiver) is used to convert the TTL level signals from the FT2233HP/FT2232HP to RS422 levels. The PWREN# signal is used to power down the level shifters such that they operate in a low quiescent current when the USB interface is in suspend mode. Copyright © Future Technology Devices International Limited 22 FT2232HP/FT2233HP Datasheet Datasheet Version 1.0 Document No.: FT_001474 4.3.3 Clearance No.: FTDI#556 RS485 Configuration Figure 4.4 illustrates how the FT2233HP/FT2232HP can be configured as a dual RS485 interface. The FT2233HP/FT2232HP can have all 2 channels connected as RS485. Figure 4.4 Dual RS485 Configurations In this case both channel A and channel B are configured as RS485 operating at TTL levels and a level converter device (half duplex RS485 transceiver) is used to convert the TTL level signals from the FT232H to RS485 levels. It has separate enables on both the transmitter and receiver. With RS485, the transmitter is only enabled when a character is being transmitted from the UART. The TXDEN pins on the FT2233HP/FT2232HP are provided for exactly that purpose, and so the transmitter enables are wired to the TXDEN‟s. The receiver enable is active low, so it is wired to the PWREN# pin to disable the receiver when in USB suspend mode. RS485 is a multi-drop network – i.e. many devices can communicate with each other over a single two wire cable connection. The RS485 cable requires to be terminated at each end of the cable. Links are provided to allow the cable to be terminated if the device is physically positioned at either end of the cable. In this example the data transmitted by the FT2233HP/FT2232HP are also received by the device that is transmitting. This is a common feature of RS485 and requires the application software to remove the transmitted data from the received data stream. With the FT2233HP/FT2232HP it is possible to do this entirely in hardware – simply modify the schematic so that RXD of the FT2233HP/FT2232HP is the logical OR of the level converter device receiver output with TXDEN using an HC32 or similar logic gate. 4.4 FT245 Synchronous FIFO Interface Mode Description When channel A is configured in an FT245 Synchronous FIFO interface mode the IO timing of the signals used are shown in Error! Reference source not found., which shows details for read and write accesses. The timings are shown in Table 4.1. Note: that only a read or a write cycle can be performed at any one time. Data is read or written on the rising edge of the CLKOUT clock.

This single channel mode uses a synchronous interface to get high data transfer speeds. The chip drives a 60 MHz CLKOUT clock for the external system to use. Note that Asynchronous FIFO mode must be selected on both channels before selecting the Synchronous FIFO mode in software. 4.4.1 FT245 Synchronous FIFO Read Operation A read operation is started when the chip drives RXF# low. The external system can then drive OE# low to turn around the data bus drivers before acknowledging the data with the RD# signal going low. The first data byte is on the bus after OE# is low. The external system can burst the data out of the chip by keeping RD# low or it can insert wait states in the RD# signal. If there is more data to be read it will change on the clock following RD# sampled low. Once all the data has been consumed, the chip will drive RXF# high. Any data that appears on the data bus, after RXF# is high, is invalid and should be ignored. 4.4.2 FT245 Synchronous FIFO Write Operation A write operation can be started when TXE# is low. WR# is brought low when the data is valid. A burst operation can be done on every clock providing TXE# is still low. The external system must monitor TXE# and its own WR# for each byte of data to check that data has been accepted. Both TXE# and WR# must be low for data to be accepted. 4.5 FT245 Asynchronous FIFO Interface Mode Description The FT2233HP/FT2232HP can be configured as a dual channel asynchronous FIFO interface. This mode is similar to the synchronous FIFO interface with the exception that the data is written to or read from the FIFO on the falling edge of the WR# or RD# signals. This mode does not provide a CLKOUT signal and it does not expect an OE# input signal. The following diagrams illustrate the asynchronous FIFO mode timing.

It can also be used to program SRAM based FPGA’s over USB. The MPSSE interface is designed to be flexible so that it can be configured to allow any synchronous serial protocol (industry standard or proprietary) to be implemented using the FT2233HP/FT2232HP. MPSSE is only available on channel A and channel B. MPSSE is fully configurable, and is programmed by sending commands down the data stream. These can be sent individually or more efficiently in packets. MPSSE is capable of a maximum sustained data rate of 30 Mbits/s. When a channel is configured in MPSSE mode, the IO timing and signals used are shown in Figure 4.8 and Table 4.3 MPSSE Signal Timings Note: These timing numbers are preliminary and subject to change. . These show timings for CLKOUT=30MHz. CLKOUT can be divided internally to be provide a slower clock.

MPSSE mode is enabled using FT_SetBitMode driver command. A hex value of 2 will enable it, and a hex value of 0 will reset the device. See application note AN2232-02, “Bit Mode Functions for the FT2232” for more details and examples. The MPSSE command set is fully described in application note AN_108 – “Command Processor for MPSSE and MCU Host Bus Emulation Modes”. The following additional application notes are available for configuring the MPSSE:    4.6.1 AN_109 – “Programming Guide for High Speed LibMPSSEI2C DLL” AN_110 – “Programming Guide for High Speed LibMPSSEJTAG DLL” AN_111 – “Programming Guide for High Speed LibMPSSESPI DLL” MPSSE Adaptive Clocking Adaptive clocking is a new MPSSE feature added to the FT2233HP/FT2232HP MPSSE engine. The mode is effectively handshaking the CLK signal with a return clock RTCK. This is a technique used by ARM processors. The FT2233HP/FT2232HP will assert the CLK line and wait for the RTCK to be returned from the target device to GPIOL3 line before changing the TDO (data out line).

See: AN108 - Command Processor For MPSSE and MCU Host Bus Emulation Modes. 4.7 MCU Host Bus Emulation Mode MCU host bus emulation mode uses both of the FT2233HP/FT2232HP’s A and B channel interfaces to make the chip emulate a standard 8048/8051 MCU host bus. This allows peripheral devices for these MCU families to be directly connected to USB via the FT2233HP/FT2232HP. The lower 8 bits (AD7 to AD0) is a multiplexed Address / Data bus. A15 to A8 provide upper (extended) addresses. There are 4 basic operations:1) 2) 3) 4) Read (does not change A15 to A8) Read Extended (changes A15 to A8) Write (does not change A15 to A8) Write Extended (changes A15 to A8) MCU Host Bus Emulation mode is enabled using FT_SetBitMode driver command. A hex value of 8 will enable it, and a hex value of 0 will reset the device. The FT2233HP/FT2232HP operates in the same way as the FT2232D. See application note AN2232-02, “Bit Mode Functions for the FT2232D” for more details and examples. The MCU Host Bus Emulation Mode command set is fully described in application note AN_108 – “Command Processor for MPSSE and MCU Host Bus Emulation Modes”. When MCU Host Bus Emulation mode is enabled the IO signal lines on both channels work together and the pins are configured. The following sections give some details of the read and write cycle waveforms and timings. The CLKOUT output clock can operate up to 60MHz. In Host Bus Emulation mode the clock divisor has no effect. The clock divisor is used for serial data and is a different part of the MPSSE block. In host bus emulation the 60MHz clock is always output and doesn’t change with any commands. 4.7.1 MCU HOST Bust Emulation Mode Signal Timing – Write Cycle Figure 4.11 MCU Host Bus Emulation Mode Signal Waveforms – WRITE Cycle Copyright © Future Technology Devices International Limited 28 FT2232HP/FT2233HP Datasheet Datasheet Version 1.0 Document No.: FT_001474 Clearance No.: FTDI#556 Table 4.4 MCU Host Bus Emulation Mode Signal Timings – WRITE Cycle When Div By 5 is on the device will return 2 bytes (the same value) when doing a read.

IORDY can be held low permanently to extend all cycles. 4.7.2 MCU Host Bus Emulation Mode Signal Timing – Read Cycle Figure 4.12 MCU Host Bus Emulation Mode Signal Waveforms – READ cycle Table 4.5 MCU Host Bus Emulation Mode Signal Timings– READ cycle Copyright © Future Technology Devices International Limited 29 FT2232HP/FT2233HP Datasheet Datasheet Version 1.0 Document No.: FT_001474 Clearance No.: FTDI#556 When Div By 5 is on the device will return 2 bytes when doing a read.

IORDY can be held low permanently to extend all cycles. An example of the MCU Host Emulation Interface enabling a USB interface to CAN Bus using a CANBus Controller is shown in the figure. Figure 4.13 MCU Host Emulation Example using a CANBus Controller 4.8 Fast Opto-Isolated Serial Interface Mode Description Fast Opto-Isolated Serial Interface Mode provides a method of communicating with an external device over USB using 4 wires that can have opto-isolators in their path, thus providing galvanic isolation between systems. If either channel A or channel B is enabled in Fast Opto-Isolated Serial mode then the pins on channel B are switched to the fast serial interface configuration. The I/O interface for fast serial mode is always on channel B, even if both channels are being used in this mode. An address bit is used to determine the source or destination channel of the data. It therefore makes sense to always use at least channel B or both for fast serial mode, but not A own its own. Fast serial mode is enabled by setting the appropriate bits in the external EEPROM. The fast serial mode can be held in reset by setting a bit value of 10 using the Set Bit Bang Mode command. While this bit is set the device is held reset – data can be sent to the device, but it will not be sent out by the device until the device is enabled again. This is done by sending a bit value of 0 using the set bit mode command. See application note AN2232L-02, “Bit Mode Functions for the FT2232D for more details and examples. When either Channel B or both Channel A and B are configured in Fast Opto-Isolated Serial Interface mode the IO timing of the signals used are shown in the figure given below. The timings are shown in Table 4.6.

If the FT2233HP/FT2232HP have data ready to send, it will drive FSDO output low to indicate the start bit. It will not do this if it is currently receiving data from the external device. This is illustrated in the figure given below -. FSCLK FSDO 0 Start Bit D0 D1 D2 D3 D4 D5 D6 D7 Data Bits - LSB first SRCE Source Bit Figure 4.15 Fast Opto-Isolated Serial Interface Output Data Notes: 1. The first bit output (Start bit) is always 0. 2. FSDO is always sent LSB first. 3. The last serial bit output is the source bit (SRCE). It indicates which channel the data has come from. A ‘0’ means that it has come from Channel A, a ‘1’ means that it has come from Channel B. 4. If the target device is unable to accept the data when it detects the START bit, it should stop the FSCLK until it can accept the data. 4.8.2 Incoming Fast Serial Data An external device is allowed to send data into the FT2233HP/FT2232HP if FSCTS is high. On receipt of a zero START bit on FSDI, the FT2233HP/FT2232HP will drop FSCTS on the next positive clock edge. The data from bits 0 to 7 are then clocked in (LSB first). The last bit (DEST) determines where the data will be written to. The data can be sent to either channel A or to channel B. If DEST= ‘0’, the data is sent to channel A, (assuming channel A is enabled for fast serial mode, otherwise the data is sent to channel B). If DEST= ‘1’ the data is sent to channel B, (assuming channel B is enabled for fast serial mode, otherwise the data will go to channel A. (Either channel A, channel B or both channels must be enabled as fast serial mode or the function is disabled). This is illustrated in the figure given below FSCTS FSCLK FSDI 0 Start Bit D0 D1 D2 D3 D4 D5 D6 Data Bits - LSB first D7 DEST Destination Bit Figure 4.16 Fast Opto-Isolated Serial Interface Input Data Notes: 1. The first bit input (Start bit) is always 0. 2. FSDI is always received LSB first. 3. The last received serial bit is the destination bit (DEST).It indicates which channel the data should go to. A ‘0’ means that it should go to channel A, a ‘1’ means that it should go to channel B.

The target device should ensure that CTS is high before it sends data. CTS goes low after data bit 0 (D0) and stays low until the chip can accept more data. 4.8.3 Fast Opto-Isolated Serial Data Interface Example The following example, (figure given below) shows two Agilent HCPL-2430 (see the semiconductor section at www.agilent.com high speed opto-couplers used to optically isolate an external device which interfaced to USB using the FT2233HP/FT2232HP. In this example VCC5V is the USB VBUS supply and VCCE is the supply to the external device. Care must be taken with the voltage used to power the photo-LED’s. It must be the same voltage as that the FT2233HP/FT2232HP I/Os are driving to, or the LED’s may be permanently on. Limiting resistors should be fitted in the lines that drive the diodes. The outputs of the opto-couplers are open-collector and require a pull-up resistor. Figure 4.17 Fast Opto-Isolated Serial Interface Example 4.9 CPU-Style FIFO Interface Mode Description CPU-style FIFO interface mode is designed to allow a CPU to interface to USB via the FT2233HP/FT2232HP. This mode is enabled in the external EEPROM. The interface is achieved using a chip select bit (CS#) and address bit (A0). When either Channel A or Channel B are in CPU-style Interface mode the IO signal lines are configured as given in Table 3.12. This mode uses a combination of CS# and A0 to determine the operation to be carried out. The following truth-table, Table 4.7, gives the decode values for particular operations.

The FT2233HP/FT2232HP channel A or channel B can be configured as a bit-bang interface. There are two types of bit-bang modes: synchronous and asynchronous. 4.10.1 Asynchronous Bit-Bang Mode Asynchronous Bit-Bang mode is the same as BM-style Bit-Bang mode, except that the internal RD# and WR# strobes (RDSTB# and WRSTB#) are now brought out of the device to allow external logic to be clocked by accesses to the bit-bang IO bus. On either or both channels any data written to the device in the normal manner will be self-clocked onto the data pins (those which have been configured as outputs). Each pin can be independently set as an input or an output. The rate that the data is clocked out at is controlled by the baud rate generator. For the data to change there has to be new data written, and the baud rate clock has to tick. If no new data is written to the channel, the pins will hold the last value written. 4.10.2 Synchronous Bit-Bang Mode The synchronous Bit-Bang mode will only update the output parallel port pins whenever data is sent from the USB interface to the parallel interface. When this is done, the WRSTB# will activate to indicate that the data has been read from the USB Rx FIFO buffer and written out on the pins. Data can only be received from the parallel pins (to the USB Tx FIFO interface) when the parallel interface has been written to. With Synchronous Bit-Bang mode data will only be sent out by the FT2233HP/FT2232HP if there is space in the FT2233HP/FT2232HP USB TXFIFO for data to be read from the parallel interface pins. This Synchronous Bit-Bang mode will read the data bus parallel I/O pins first, before it transmits data from the USB RxFIFO. It is therefore 1 byte behind the output, and so to read the inputs for the byte that you have just sent, another byte must be sent. For example: (1) Pins start at 0xFF Send 0x55,0xAA Pins go to 0x55 and then to 0xAA Data read = 0xFF,0x55 (2) Pins start at 0xFF Send 0x55,0xAA,0xAA (repeat the last byte sent) Pins go to 0x55 and then to 0xAA Data read = 0xFF,0x55,0xAA Synchronous Bit-Bang Mode differs from Asynchronous Bit-Bang mode in that the device parallel output is only read when the parallel output is written to by the USB interface. This makes it easier for the controlling program to measure the response to a USB output stimulus as the data returned to the USB interface is synchronous to the output data. Asynchronous Bit-Bang mode is enabled using Set Bit Bang Mode driver command. A hex value of 1 will enable Asynchronous Bit-Bang mode. Synchronous Bit-Bang mode is enabled using Set Bit Bang Mode driver command. A hex value of 4 will enable Synchronous Bit-Bang mode. See application note AN2232-02, “Bit Mode Functions for the FT2232 for more details and examples of using the bit-bang modes.

This indicates that the host PC has written new data to the I/O parallel data pins t6 WRSTB# goes inactive Table 4.10 Synchronous Bit-Bang Mode Timing Interface Example Timings WRSTB# = this output indicates when new data has been written to the I/O pins from the Host PC (via the USB interface). RDSTB# = this output rising edge indicates when data has been read from the I/O pins and sent to the Host PC (via the USB interface). The WRSTB# goes active in t4. The WRSTB# goes active when data is read from the USB RXFIFO (i.e. sent from the PC). The RDSTB# goes inactive when data is sampled from the pins and written to the USB TXFIFO (i.e. sent to the PC). The FT_SetBitMode command to the FT2233HP/FT2232HP are used to setup the bit-mode. This command also contains a byte wide data mask to set the direction of each bit. The direction on each pin doesn’t change unless a new FT_SetBitMode command is used to modify the direction. The WRSTB# and RDSTB# strobes is only a guide to what may be happening depending on the direction of the bus. For example if all pins are configured as inputs, it is still necessary to write to these pins in order to get the FT2233HP/FT2232HP to read those pins even though the data written will never appear on the pins. Signals and data-flow are illustrated in the figure given below - WRSTB# USB Rx FIFO/ Buffer USB Parallel I/O data Parallel I/O pins USB Tx FIFO/ Buffer RDSTB# Figure 4.21 Bit-bang Mode Dataflow Illustration Diagram Copyright © Future Technology Devices International Limited 35 FT2232HP/FT2233HP Datasheet Datasheet Version 1.0 Document No.: FT_001474 Clearance No.: FTDI#556 4.11 RS232 UART Mode LED Interface Description When configured in UART mode the FT2233HP/FT2232HP has two IO pins on each channel dedicated to controlling LED status indicators, one for transmitted data the other for received data. When data is being transmitted / received the respective pins drive from tri-state to low in order to provide indication on the LED’s of data transfer. A digital one-shot timer is used so that even a small percentage of data transfer is visible to the end user. Figure 4.22 Dual LED UART Configuration The above figure shows a configuration using two individual LED’s – one for transmitted data the other for received data. Figure 4.23 Single LED UART Configuration The above figure illustrates how to transmit and receive LED indicators are wire-OR’ed together to give a single LED indicator which indicates any transmit or receive data activity. Note that the LED’s are connected to the same supply as VCCIO. 4.12 Send Immediate / Wake Up (SIWU#) The SIWU# function is available in the FIFO modes and in bit-bang mode. The Send Immediate portion is used to flush data from the chip back to the PC. This can be used to get short packets of data back to the PC without waiting for the latency timer to expire. This mechanism should only be used when you have stopped sending data to the chip to avoid overrun. The data transfer is flagged to the USB host by the falling edge of the signal.

When the pin is being used to flush the buffer (Send Immediate), a 250ns negative pulse on this pin is required. Notes 1. When using remote wake-up, ensure the resistors are pulled-up in suspend. Also ensure peripheral designs do not allow any current sink paths that may partially power the peripheral. 2. If remote wake-up is enabled, a peripheral is allowed to draw up to 2.5mA in suspend. If remote wake-up is disabled, the peripheral must draw no more than 500uA in suspend. 3. If a Pull-down is enabled, the FT2233HP/FT2232HP will not wake up from suspend. 4.13 FT2233HP/FT2232HP Mode Selection The two channels of the FT2233H/FT2232HP reset to two asynchronous serial interfaces. Following a reset the required mode of each channel is determined by the contents of the EEPROM (programmed using FT_PROG). The EEPROM contents determine if the two channels have been configured as FT232 asynchronous serial interface, FT245 FIFO interface, CPU-style FIFO interface or Fast Serial Interface. Following a reset, the EEPROM is read to determine which mode is configured. After device enumeration, an FT_SetBitMode command (refer to D2XX_Programmers_Guide) can be sent to the USB driver to switch the selected interface into the required mode – asynchronous bit-bang, synchronous bit-bang or MPSSE. When in FT245 FIFO mode, the FT_SetBitMode command can be used to select either Synchronous FIFO (FT_SetBitMode = 0x40) or Asynchronous FIFO mode. (Note that Asynchronous FIFO mode must be selected on both channels before selecting the Synchronous FIFO mode. This means that an EEPROM is needed to initially configure Asynchronous FIFO mode before software configures the Synchronous FIFO mode). When Synchronous FIFO mode selected, channel A uses all the memory resources of channel B. As such channel B is then not available. In this case the state of the channel B pins is determined when the configuration is switched to Asynchronous FIFO mode. If channel B had not been used for any data transfer before configuration of Asynchronous FIFO mode, then the channel B pins will remain in their default mode (D7:0=tri-stated but pulled high trough 75K resistor, TXE# =low, RXF# =high. RD# and WR# are inputs and should be pulled high). An MPSSE command, set_data_bits can be used to configure the channel B pins as inputs before configuring channel A as Synchronous FIFO. This avoids the channel B pins driving against any interfaces (such as SPI) which may have been configured previous to any switching of channel A to Synchronous FIFO mode.

There are two PD ports in the device (FT2233HPQ and FT2233HPL only), one port is with the legacy USB 2.0 port to form USB PD port as a power sink or source, and the other port is standalone PD port as a sink which is used to connect to PD power source. Power Delivery function is designed to meet PD2.0/3.0 specification. If the device is configured to be operated in legacy USB2.0 mode it will be backward compatible to FT2232H in terms of USB2.0 and its peripheral IOs functions.

When operating as a Sink, GPIO pins are used for LOAD_EN and ISET. Depends on the kind of profile negotiated, the appropriate ISET GPIO will go high followed by LOAD_EN pin. The timing between this ISET going high to LOAD_EN can be as high as 12.5uS. When operating as a Source, GPIO pins are used as power supply controller. During Source operation, initial voltage will be 5V and then depends on the profile setting, the PD controller can negotiate a higher voltage. The switching from 5V to higher Voltage or vice versa is by switching GPIOs. 5V could be controlled by one Pin where as another higher Voltage is controlled by another pin. For example, below table shows a sample GPIO states for 3 different voltage cases. 5v PS_EN HIGH GPIO_9v LOW GPIO_20v LOW 9V HIGH HIGH LOW 20V HIGH LOW HIGH Table 4.13 Example GPIO states for power control In this case 5V to 9V or 5v to 20V is just an additional GPIO pin going high. In this case the timing does not matter. However in the scenario when the profile changes from 9V to 20V, there is one GPIO going Low where as another one going high. In this case the delay between one pin going low to another pin going high can be as high as 12.5uS.
