The core processor uses a 32-bit I/O system bus to connect to all of the peripherals.                  USB2.0 host controller USB2.0 peripheral controller 10/100Mbps Ethernet controller (FT900 and FT901 only) Two CAN bus interfaces (FT900 and FT902 only) Real Time Clock One-Wire debugger interface One SPI master interface and two SPI slave interfaces Two I2C bus interfaces One I2S bus interface UART interface Four timers and a 32-bit watchdog timer Camera parallel interface SD host controller PWM motor controller 10-bit DAC0/1 channel 10-bit ADC1-7 channel General purpose I/O interface The functions for each controller / interface are briefly described in the following subsections. 4.2 FT32 Core Processor The FT32 core processor is running at frequencies of up to 100MHz. The processor contains the CPU itself with control logic and its 256kB program memory and 64kB data memory. The outside connections for the core processor are the memory-mapped I/O interface, the interrupt interface, asynchronous reset and the system clock. 4.3 256kB Flash Memory The internal 256kB Flash memory is used to store a boot loader or user application of the FT90x series. It is a high performance and low power consumption memory that supports upto 80MHz serial clock. The system will perform memory copy from Flash memory to CPU program memory automatically after system power on. 4.4 Boot Sequence After the initial memory copy completes, the CPU jumps to program memory location zero. This may be the start of the user application which is stored in advance in Flash memory, or a boot loader only which allows program memory to perform modification via (e.g.) UART or USB. The option of a boot loader is a special purpose routine in the FT90x series embedded microcontroller. It is a small routine stored in the Flash memory. Typically the boot loader is 14kbytes in size, and is loaded at the top of the available memory.

When an interrupt occurred, the Interrupt Service Route (ISR) will process this event via the CPU. The ISR vector range is from 0 to 31, which corresponds to interrupt 0 to 31. See Table 4-1 information. Each interrupt shall be assigned the interrupt vector number and priority before use. By default, the highest priority interrupt is interrupt 0, and the lowest is interrupt 31. However, the interrupt priority can be rearranged by register settings and also allows multiple interrupts at the same priority. To prevent the loss and delay of high priority interrupts, the FT90x series uses nested interrupts if enabled. Nested interrupts allow interrupt requests of a high priority to pre-empt interrupt requests of a lower priority. FT90x series supports up to 16-levels deep of nested interrupts. The interrupt controller has a global interrupt mask bit to temporarily block all interrupts. If this bit is set to “1”, then with the exception of an interrupt assigned priority as “0”, which is a non-maskable interrupt (NMI) input, all interrupts are masked. See Table 4-2 for FT90x series default interrupt priority.

The watchdog timer is controlled from the main clock. The watchdog can be initialized with a 5-bit register. The value of this register points to a bit of the 32-bit counter which will be set by the application firmware. As the timer decrements, an interrupt occurs when the timer rolls over. Once started and initialized the watchdog can’t be stopped. It can only be cleared by writing into a register. The four user timers can be controlled from the main clock or a common 16-bit pre-scaler, which can be selected by each timer individually. These timers can be started, stopped and cleared / initialized. The current value of all timers can be read from registers. All timers can count up / down and signal an interrupt when the timer rolls over. The timers can also be configured to be one-shot or in continuous mode. 4.16.1 Features:       Four user timers with pre-scaler. Supports 16-bit pre-scaler with system clock reference.

In Master mode, two clock sources are to be provided externally. One is 24.576MHz and the other is 22.5792MHz. The LRCLK, BCLK and MCLK as output signals will be generated by the Master based on sampling rate and data bit length. In Slave mode, the LRCLK and BCLK are input signals to the FT900. The MCLK source is not used in this case. The application can configure the two clock source pins (I2SM_CLK22, I2SM_CLK24) to GPIO operation. 4.17.1 Features:        Configure I2S interface as master or slave.

The interface will provide a clock to the external camera module at a Max rate of 25MHz. Camera control signals are VSYNC, HREF and PCLK. The VSYNC signal determines when a new frame begins. The HREF signal represents the period of data transfer of a row in the Copyright © 2015 Future Technology Devices International Limited 32 FT900/1/2/3 Embedded Microcontroller Datasheet Version 1.1 Document No.: FT_000965 Clearance No.: FTDI#421 transmitted frame. When the HREF signal is active, there is valid data over the data lines every pixel clock (PCLK) cycle. The PCLK signal indicates a valid data byte over the data lines and it is used as a transfer trigger. 4.18.1 Features:      Configure camera registers via I2C two-wire interface. 8-bit data is clocked by an external clock provided by the camera module. With VSYNC, HREF and PCLK control signals. Programmable data capture trigger position. 2kB FIFO for camera capture data. 4.19 PWM The FT90x series supports 7 separate independent PWM output channels. All channels share an 8-bit pre-scaler to scale the system clock frequency to the desired channels. Each channel has its own 16-bit comparator value. This is the value that would be matched to a preset 16-bit counter. When a channel’s 16-bit comparator value matches that of the 16-bit counter, the corresponding PWM channel output will toggle. This 16-bit comparator value will continue to count until it reaches its preset value, and the counter will just roll over. A special feature allows the 7 channels each to also toggle its own output based on the comparison results of other channels. Hence each channel potentially can have up to 8 toggle edges. The PWM signal generated can be output as a single-shot or continuous output. The PWM counter also supports an external trigger. There are 6 GPIOs selectable for an external trigger. PWM channel 0 and channel 1 can double as a stereo 11 KHz or 22 KHz PCM audio channel. Once this feature is setup, the 16-bit or 8-bit PCM audio data can be downloaded to the PWM local FIFO which can hold up to 64 bytes stereo or 128 bytes mono audio data. The data will playback based on the pre-scaler and 16-bit counter, and the data will be automatically scaled to fit in the playback period if necessary. 4.19.1 Features:       Support 7 PWM output channels. Support single-shot or continuous PWM data output. Support external GPIO trigger. Support 16-bit / 8-bit stereo PCM audio data output.

The oscillator clock source comes from either an external 12 MHz crystal or a 12 MHz square wave clock. The external crystal is connected across XI/CLKIN and XIO in the configuration shown in Section 6.1. The optional external clock input is connected to XI/CLKIN only. 4.24.2 Phase Locked Loop The internal PLL takes a 12 MHz clock input from a crystal oscillator. The PLL outputs the 100 MHz system clock frequency to the CPU processor and other peripheral circuits. Each peripheral has an individual enable control signal to gate the clock source. 4.24.3 32.768 KHz RTC Oscillator The RTC oscillator provides a clock to the RTC time counter. Either an external 32.768 kHz crystal or a 32.768 kHz square wave clock can be used as the clock source. The external crystal is connected across RTC_XI/RTC_CLKIN and RTC_XIO in the configuration shown in Section 6.2. The optional external clock input is connected to RTC_XI/RTC_CLKIN only. 4.24.4 Internal Slow Clock Oscillator The internal slow clock oscillator provides at least 5ms slow clock source to generate an interrupt for the USB2.0 device remote wake-up feature. A USB2.0 device with remote wakeup capability may not generate resume signalling unless the bus has been continuously in the idle state for 5ms. The detail description for USB2.0 suspend/resume, please refer to USB2.0 specification chapter7.1.7.7. 4.25 Power Management 4.25.1 Power Supply The FT90x series may be operated with a single supply of +3.3V applied to VCCIO3V3, VUSB3V3, VETH3V3 and VCC3V3A pins. The +1.2V internal regulator VOUT1 provides the power to the core circuit after VCCIO3V3 power on and the system will generate a Power on Reset (POR) pulse when the output voltage rises above the POR threshold. The second +1.2V internal regulator VOUT2 will provide the power to the Ethernet transceiver when VETH3V3 gets the power supply. Copyright © 2015 Future Technology Devices International Limited 35 FT900/1/2/3 Embedded Microcontroller Datasheet Version 1.1 Document No.: FT_000965 Clearance No.: FTDI#421 4.25.2 Power Down Mode Power down mode applies to the entire system. In the power down mode, the system 12MHz oscillator and PLL both switch off and the system clock to the core and all peripherals stop except for the RTC oscillator and internal regulator. The internal regulator retains the power for the core and RTC running. An interrupt from GPIO or wake-up events from the USB2.0 peripheral controller and host controller can wake-up the system from the power down mode independently. If the USB2.0 host controller was used and the respective interrupt bit enabled before the system entered into power down mode, then the following events can wake-up the system.     Remote wake-up interrupt to USB2.0 host controller. USB device connected interrupt to USB2.0 host controller. USB device disconnected interrupt to USB2.0 host controller. USB host controller detected the over-current (OC) protection event. If the USB2.0 peripheral controller was used and the respective interrupt bit was also enabled before the system entered into power down mode, then the following events can wake-up the system.     USB2.0 peripheral controller detects connect interrupt. USB2.0 peripheral controller detects disconnect interrupt. USB host issue reset signal to USB2.0 peripheral controller. USB host issue resume signal to USB2.0 peripheral controller.

The EREFSET connects an external resistor R (12 KΩ ±1%) to GND to provide a reference voltage for the Ethernet transceiver. There are two Ethernet LEDs output for TX/RX transmission, Full-duplex/Half-duplex, Collision, Link or 10/100 Mb/s Speed indication. The required function should be set in the chip registers before using the LED indicator.
