The SL811HS can interface to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1. The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed transceivers. The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode. The SL811HS data port and microprocessor interface provide an 8-bit data path I/O or DMA bidirectional, with interrupt support to allow easy interface to standard microprocessors or microcontrollers such as Motorola or Intel CPUs and many others. Internally, the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer. The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.

SL811HS USB Host/Slave Controller Functional Block Diagram 4.2 SL811HS Host or Slave Mode Selection [Master/Slave Mode] SL811HS can work in two modes—host or slave. For slave-mode operation and specification, please refer to the SL811S specification. This data sheet only covers host-mode operation. 4.3 Features • The only USB Host/Slave controller for embedded systems in the market with a standard microprocessor bus interface. • Supports both full-speed (12 Mbps) and low-speed (1.5 Mbps) USB transfer 4.3.1 USB Specification Compliance • Conforms to USB Specification 1.1 4.3.2 CPU Interface • Operates as a single USB host or slave under software control • Low-speed 1.5 Mbps, and full speed 12 Mbps, in both master and slave modes • Automatic detection of either low- or full-speed devices • 8-bit bidirectional data, port I/O (DMA supported in slave mode) • On-chip SIE and USB transceivers • On-chip single root HUB support • 256-byte internal SRAM buffer, ping-pong operation • Operates from 12- or 48-MHz crystal or oscillator (built-in DPLL) • 5 V-tolerant interface • Suspend/resume, wake up, and low-power modes are supported • Auto-generation of SOF and CRC5/16 • Auto-address increment mode, saves memory Read/Write cycles • Development kit including source code drivers is available • Backward-compatible with SL11H, both pin and functionality • 3.3V power source, 0.35 micron CMOS technology • Available in both a 28-pin PLCC package (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Document #: 38-08008 Rev. *A Page 5 of 29 SL811HS 4.4 Data Port, Microprocessor Interface The SL811HS microprocessor interface provides an 8-bit bidirectional data path along with appropriate control lines to interface to external processors or controllers. The control lines, Chip Select, Read and Write input strobes and a single address line, A0, along with the 8-bit data bus, support programmed I/O or memory mapped I/O designs. Access to memory and control register space is a simple two step process, requiring an address Write with A0 set = “0,” followed by a register/memory Read or Write cycle with address line A0 set = “1.” In addition, DMA bidirectional interface in slave mode is available with handshake signals such as DREQ, ACK, WR, RD, CS and INTR. Please refer to the SL811S spec. The SL811HS Write or Read operation terminates when either nWR or nCS goes inactive. For devices interfacing to the SL811HS, that deactivate the Chip Select nCS before the Write nWR, the data hold timing should be measured from the nCS and will be the same value as specified. Thus, both Intel− and Motorola-type CPUs can work easily with the SL811HS without any external glue logic requirements. 4.5 Interrupt Controller The SL811HS interrupt controller provides a single output signal (INTRQ) that can be activated by a number of events that may occur as result of USB activity. Control and status registers are provided to allow the user to select single or multiple events, which will generate an interrupt (assert INTRQ), and lets the user view interrupt status. The interrupts can be cleared by writing to the appropriate register (the Status Register at address 0x0d). 4.6 Buffer Memory The SL811HS contains 256 bytes of internal buffer memory. The first 16 bytes of memory represent control and status registers for programmed I/O operations. The remaining memory locations are used for data buffering (max. 240 Bytes). Access to the registers and data memory is through an external microprocessor, 8-bit data bus, in either of two addressing modes, indexed or, if used with multiplexed address/data bus interfaces, direct access. With indexed addressing, the address is first written to the device with the A0 address line LOW, then the following cycle with A0 address line HIGH is directed to the specified address. USB transactions are automatically routed to the memory buffer. Control registers are provided, so that pointers and block sizes in buffer memory can be can set up. 4.6.1 Auto Address Increment Mode The SL811HS supports auto-increment mode for Read or Write Cycles, A0 mode. In A0 mode, the Micro Controller sets up the address only once. On any subsequent DATA Read or Write access, the internal address pointer will advance to the next DATA location. 4.6.1.1 For example Write 0x10 to SL811HS in address cycle (A0 is set LOW) Write 0x55 to SL811HS in data cycle (A0 is set HIGH) -> Write 0x55 to location 0x10 Write 0xaa to SL811HS in data cycle (A0 is set HIGH) -> Write 0xaa to location 0x11 Write 0xbb to SL811HS in data cycle (A0 is set HIGH) -> Write 0xbb to location 0x12 The advantage of auto address increment mode is that it reduces the number of SL811HS memory Read/Write cycles required to move data to/from the device. For example, transferring 64-bytes of data to/from SL811HS using auto increment mode, will reduce the number of cycles to 1 Address Write and 64 Read/Write Data cycles, compared to 64 Address Writes and 64 Data Cycles for Random Access. 4.7 PLL Clock Generator Either a 12-MHz or a 48-MHz external crystal can be used with the SL811HS. Two pins, X1 and X2, are provided to connect a low-cost crystal circuit to the device as shown in Figure 4-2 and Figure 4-3. If an external 48-MHz clock source is available in the application, it can be used instead of the crystal circuit by connecting the source directly to the X1 input pin. When a clock is used, the X2 pin is left unconnected.

Please note that these specifications are generally found as standard crystal values and are therefore less expensive than custom values. If crystals are used in series circuits, load capacitance is not applicable. Load capacitance of parallel circuits is a requirement. 12-MHz Crystals: Frequency Tolerance: Operating Temperature Range: Frequency: Frequency Drift over Temperature: ESR (Series Resistance): Load Capacitance: Shunt Capacitance: Drive Level: Operating Mode: ±100 ppm or better 0°C to 70°C 12 MHz ± 50 ppm 60Ω 10 pF min. 7 pF max. 0.1–0.5 mW fundamental 48-MHz Crystals: Frequency Tolerance: Operating Temperature Range: Frequency: Frequency Drift over Temperature: ESR (Series Resistance): Load Capacitance: Shunt Capacitance: Drive Level: Operating Mode: ±100 ppm or better 0°C to 70°C 48 MHz ± 50 ppm 40 Ω 10 pF min. 7 pF max. 0.1–0.5 mW third overtone 4.8 USB Transceiver The SL811HS has a built in transceiver that meets USB Specification 1.1. The transceiver is capable of transmitting and receiving serial data at USB full speed (12 Mbits) and low speed (1.5 Mbits). The driver portion of the transceiver is differential while the receiver section is comprised of a differential receiver and two single-ended receivers. Internally, the transceiver interfaces to the Serial Interface Engine (SIE) logic. Externally, the transceiver connects to the physical layer of the USB. 5.0 SL811HS Registers Operation of the SL811HS is controlled through 16 internal registers. A portion of the internal RAM is devoted to the control register space, and access is through the microprocessor interface. The registers provide control and status information for transactions on the USB, microprocessor interface, and interrupts. Any Write to control register 0FH will enable the SL811HS full features bit. This is an internal bit of the SL811HS that enables additional features not supported by the SL11H. For SL11H hardware backward compatibility, this register should not be accessed. The table below shows the memory map and register mapping of both the SL11H and SL811HS. The SL11H is shown for users upgrading to the SL811HS.

The first group is referred to as USB Control registers. These registers enable and provide status for control of USB transactions and data flow. The second group of registers provides control and status for all other operations. 5.1 Register Values on Power-up and Reset The following registers initialize to zero on power-up and reset: • USB-A/USB-B Host Control Register [00H, 08H] bit 0 only • Control Register 1 [05H] • USB Address Register [07H] • Current Data Set/Hardware Revision/SOF Counter LOW Register [0EH] All other registers power-up and reset in an unknown state and should be initialized by firmware. 5.2 USB Control Registers Communication and data flow on the USB uses the SL811HS’s USB A-B Control Registers. The SL811HS can communicate with any USB Device functions and any specific endpoints via the USBA or USBB register sets. The USB A-B Host Control Registers can be used in a Ping-Pong arrangement to manage traffic on the USB. The USB Host Control Register also provides a means to interrupt an external CPU or Micro Controller when one of the USB protocol transactions is completed. The table above shows the two sets of USB Host Control Registers, the “A” set and “B” set. The two register sets allow for overlapped operation. When one set of parameters is being set up, the other is transferring. On completion of a transfer to an endpoint, the next operation will be controlled by the other register set. Note. On the SL11H, the USB-B set control registers are not used. The USB-B register set can be used only when SL811HS mode is enabled by initializing register 0FH. The SL811HS USB Host Control has two groups of five registers each, which map in the SL811HS memory space. These registers are defined in the following tables.

If set = “1” a preamble token is transmitted prior to transfer of low-speed packet. If set = “0,” preamble generation is disabled. Function Allows enabled transfers when set = “1.” Cleared to “0” when transfer is complete. When set = “1” allows transfers to this endpoint. When set “0” USB transactions are ignored. If Enable = “1” and Arm = '0' the endpoint will return NAKs to USB transmissions. When set = “1” transmit to Host. When “0” receive from Host. SL11H (hex) Address 00H 01H 02H 03H 04H Reserved Reserved Reserved Reserved Reserved SL811HS (hex) Address 00H 01H 02H 03H 04H 08H 09H 0AH 0BH 0CH Bit Position 0 1 2 3 4 5 6 7 • Bit 3 is reserved for future usage. • The SL811HS uses bit 5 to enable transfer of a data packet after a SOF packet is transmitted. When this bit set “1,” the next enabled packet will be sent after next SOF. If set = “0” the next packet is sent immediately if the SIE is free. • The SL811HS automatically generates preamble packets when bit 7 is set. This bit is only used to send packets to a low-speed device through a hub. To communicate to a full speed device, this bit is set to zero. For example, when SL811HS communicates to a low-speed device via the HUB: — SL811HS SIE should set to operate at 48 MHz, i.e., bit 5 of register 05H should be set = “0.” — Bit 6 of register 0FH should be set = “0,” set correct polarity of DATA+ and DATA– state for Full Speed. — Bit 7, Preamble Bit, should be set = “1” in Host Control register. • When SL811HS communicates directly to low-speed device: — SL811HS. Bit 5 of register 05H should be set = “1.” — Bit 6 of register 0FH should be set = “1,” DATA+ and DATA– polarity for low speed. — The state of bit 7 is ignored in this mode. 5.2.3 Example of SL811HS USB Packet Transfer SL811HS memory set-up as shown: 03h-04h Register will contain PID and Device endpoint and Device Address. 10h-FFh USB Data as required. Document #: 38-08008 Rev. *A Page 10 of 29 SL811HS 5.2.4 SOF Packet Generation The SL811HS automatically computes CRC5 by hardware. No CRC or SOF is required to be generated by external firmware for SL811HS. 5.2.5 USB-A/USB-B Host Base Address [01H, 09H] The USB-A/USB-B Base Address is a Pointer to the SL811HS memory buffer location for USB reads and writes. When transferring data OUT (Host to Device), the USB-A and USB-B can be set up prior to setting ARM on the USB-A or USB-B Host Control register. See the software implementation example. 5.2.6 USB-A/USB-B Host Base Length [02H, 0AH] The USB A/B host base register contains the maximum packet size to be transferred between the SL811HS and a slave USB peripheral. Essentially, this designates the largest packet size that can be transferred by the SL811HS. Base Length designates the size of data packet to be sent. For example, in Bulk mode the maximum packet length is 64 bytes. In ISO mode, the maximum packet length is 1023, since the SL811HS only has an 8-bit length; the maximum packet size for the ISO mode using the SL811HS is 255 – 16 bytes. When the Host Base Length register is set to zero, a Zero-Length packet will be transferred. 5.2.7 USB-A/USB-B Host PID, Device Endpoint (Write)/USB Status (Read) [03H, 0BH] This register has two modes. When read, this register provides packet status and it contains information relative to the last packet that has been received or transmitted. The register is defined as follows. Bit Position 0 1 2 3 4 5 6 7 Bit Name ACK Error Time-out Sequence Setup Overflow NAK STALL Transmission Acknowledge Error detected in transmission Time-out occurred Sequence Bit. “0” if DATA0, “1” if DATA1 “1” indicates Setup Packet Overflow condition - maximum length exceeded during receives Slave returns NAK Slave set STALL bit Function When written, this register provides the PID and Endpoint information to the USB SIE engine to be used in the next transaction. All sixteen Endpoints can be addressed by the SL811HS. D7 PID3 PID3-0 EP3-0 D6 PID2 D5 PID1 D4 PID0 D3 EP3 D2 EP2 D1 EP1 D0 EP0 4-bit PID Field (See Table Below) 4-bit Endpoint Value in Binary.

When read, this register contains the number of bytes left over (from “Length” field) after a packet is transferred. If an overflow condition occurs, i.e., the received packet from slave USB device was greater than the Length field specified, a bit is set in the Packet Status Register indicating the condition. When written, this register will contain the USB Device Address to which the Host wishes to communicate.

Document #: 38-08008 Rev. *A Page 12 of 29 SL811HS 5.3.2 J-K Programming States [bits 3 and 4 of Control Register 05H] The J-K force state control and USB Engine Reset bits can be used to generate USB reset condition on the USB. Forcing K-state can be used for Peripheral device remote wake-up, Resume and other modes. These two bits are set to zero on power-up. Bit 4 0 0 1 1 5.3.3 Bit 3 0 1 0 1 Normal operating mode Force USB Reset, D+ and D– are set LOW (SE0) Force J-State, D+ set HIGH, D– set LOW[2] Force K-State, D– set HIGH, D+ set LOW[3] Function Low-speed/Full Speed Modes [bit 5 Control Register 05H] The SL811HS is designed to communicate with either full or low-speed devices. At power-up bit 5 will be set LOW, i.e., for full speed. There are two cases when communicating with a low-speed device. When a low-speed device is connected directly to the SL811HS, bit 5 of Register 05H should be set to logic “1” and bit 6 of register 0FH, Output-Invert, needs to be set to “1” in order to change the polarity of D+ and D–. When a low-speed device is connected via a HUB to SL811HS, bit 5 of Register 05H should be set to logic “0” and bit 6 of register 0FH should be set to logic “0” in order to keep the polarity of D+ and D– for full speed. In addition, make sure that bit 7 of USB-A/USB-B Host Control Registers [00H, 08H] is set to “1.” 5.3.4 Low-power Modes [bit 6 Control Register 05H] When bit-6 (Suspend) is set to “1,” the power of the transmit transceiver will be turned off, the internal RAM will be in the suspend mode, and the internal clocks will be disabled. Note. Any activity on the USB bus (i.e., K-State, etc.) will resume normal operation. To resume normal operation from the CPU side, a data Write cycle (i.e., A0 set HIGH for a data Write cycle) should be done. 5.3.5 Interrupt Enable Register, Address [06H] The SL811HS provides an Interrupt Request Output, which can be activated on a number of conditions. The Interrupt Enable Register allows the user to select conditions that will result in an Interrupt being issued to an external CPU. A separate Interrupt Status Register is provided. It can be polled in order to determine those conditions that initiated the interrupt. (See Interrupt Status Register description.) When a bit is set to “1” the corresponding interrupt is enabled. Bit Position 0 1 2 3 4 5 6 Bit Name USB-A USB-B Reserved Reserved SOF Timer Inserted/Removed Device Detect/Resume 1 = Enable Interrupt on 1-ms SOF Timer Slave Insert/Remove Detection Enable Device Detect/Resume Interrupt USB-A Done Interrupt USB-B Done Interrupt Function • Bits 0–1 are used for the USB A/B controller interrupt. • Bit 4 is used to enable/disable the SOF timer. To utilize this bit function, bit 0 of register 05H must be enabled and the SOF counter registers 0EH and 0FH must be initialized. • Bit 5 is used to enable/disable the device inserted/removed interrupt. • When bit-6 of register 05H is set = “1,” bit 6 of this register enables the Resume Detect Interrupt. Otherwise, this bit is used to enable Device detection status as defined in the Interrupt Status Register bit definitions. Note: 2. Force K-State for low speed. 3. Force J-State for low speed.

It should not be written by the user. 5.3.7 Interrupt Status Register, Address [0DH] The ISR is a Read/Write register providing interrupt status. Interrupts can be cleared by writing to this register. To clear a specific interrupt, the register is written with corresponding bit set to “1.” Bit Position 0 1 2 3 4 5 6 7 Bit Name USB-A USB-B Reserved Reserved SOF timer Insert/Remove Device Detect/Resume D+ 1 = Interrupt on 1-ms SOF Timer Slave Insert/Remove Detection Device Detect/Resume Interrupt Value of the Data+ Pin USB-A Done Interrupt USB-B Done Interrupt Function • Bit 5 is provided to support USB cable Insertion/Removal for the SL811HS in Host Mode. This bit is set when a transition from SE0 to IDLE (device inserted) or IDLE to SE0 (device removed) occurs on the bus. • Bit 6 is shared between Device Detection status and Resume detection interrupt. When bit-6 of register 05H is set to one, this bit will be the Resume detection Interrupt bit. Otherwise, this bit is used to indicate the presence of a Device, “1” = device “Not present” and “0” = device “Present.” In this mode this bit should be checked along with bit 5 to determine whether a device has been inserted or removed. • Bit 7 provides continuous USB Data+ line status. Once it has been determined that a device has been inserted as described above with bits 5 and 6, bit 7 can be used to detect if the inserted device is low- or full-speed. 5.3.8 Current Data Set Register/Hardware Revision/SOF Counter LOW, Address [0EH] • This register has two modes: a Read from this register indicates the current SL811HS silicon revision. Bit Position 0 1 2 3 4–7 Bit Name Reserved Reserved Reserved Reserved HW Revision Reserved for slave Reserved for slave Read will be zero Read will be zero SL11H Read = 0H, SL811HS rev1.2 Read = 1H, SL811HS rev1.5 Read = 2 Function • Writing to this register will set up auto generation of SOF to all connected peripherals. This counter is based on the 12-MHz clock. To set up a 1-ms timer interval, the software must set up both SOF counter registers to the proper values. Bit Position 0–7 Bit Name SOF LOW Counter Register Function Write-only to set SOF LOW Counter Register, OEH • Example. To set up SOF for 1-ms interval, SOF counter register 0EH should be set to E0H. Document #: 38-08008 Rev. *A Page 14 of 29 SL811HS 5.3.9 SOF Counter HIGH/Control2 Register, Address [0FH, READ/WRITE] When writing to this register the bits definition are defined as follows. Bit Position 0–5 6 7 Bit Name SOF HIGH Counter Register SL811HS D+/D– Data Polarity Swap SL811HS Master/Slave selection Function Write a value or read it back to SOF HIGH Counter Register Write/Read, set “1” change polarity, “0” no change of polarity Write/Read, “1” is master, else Slave Note. Any Write to control register 0FH will enable the SL811HS full features bit. This is an internal bit of the SL811HS which enables additional features not supported by the SL11H. For SL11H hardware backward compatibility, this register should not be accessed. The USB-B register set can be used when SL811HS full feature bit is enabled. Example. To set up for 1-ms SOF time: The register 0FH contains the upper 6 bits of the SOF timer. Register 0EH contains the lower 8 bits of the SOF timer. The timer is based on a 12-MHz clock and uses a counter, which counts down to zero from an initial value. To set the timer for 1 ms time, the register 0EH should be loaded with value E0H, register 0F, Bits 0–5 should be loaded with 2EH. To start the timer, bit 0 of register 05H should be set to “1.” To load both HIGH and LOW registers with the proper values the user must follow this sequence: — Write E0H to register 0EH. — Write 2EH to register 0FH, bits 0–5. Bits 6 and 7 should be set for appropriate function: polarity and Master/Slave. — Enable bit 0 in register 05H. Note. Any Write to the 0FH register will clear the internal frame counter. Register 0FH must be written at least once after power-up. The internal frame counter is incremented after every SOF timer tick. The internal frame counter is an 11-bit counter, which is used to track the frame number. The frame number is incremented after each timer tick. Its contents are transmitted to the slave every millisecond in a SOF packet. D7 C13 D6 C12 C13–C6 D5 C11 D4 C10 D3 C9 D2 C8 D1 C7 D0 C6 Top 8 bits of 14-bit SOF counter. When read, this register will return the value of the SOF counter divided by 64. The software should use this register to determine the available bandwidth in the current frame before initiating any USB transfer. In this way, the user will be able to avoid babble conditions on the USB. For example, to determine the available bandwidth left in a frame: Maximum number of clock ticks in 1-ms time frame is 12000(1 count per 12-MHz clock period, or approximately 84 ns.) The value read back in Register 0FH is the (count × 64) × 84 ns = time remaining in current frame. USB bit time = one 12-MHz period. Value of register 0FH BBH BAH Available bit times left are between 12000 bits to 11968 (187 × 64) bits 11968 bits to 11904 (186 × 64) bits Document #: 38-08008 Rev. *A Page 15 of 29 SL811HS 6.0 SL811HS and SL811HST-AC Physical Connections This part is offered in both a 28-pin PLCC package (SL811HS) and a 48-pin TQFP package (SL811HST-AC). 6.1 6.1.1 SL811HS Physical Connections SL811HS Pin Layout nRD N C* NC* A0 VDD1 M/S D7 26 3 5 6 7 8 9 10 11 12 13 14 15 16 17 18 2 1 28 27 25 24 23 D6 D5 D4 G nd D3 D2 D1 Pins 2 and 3 should be No Connect in Host Mode.
