SL811S General Description

The SL811S/T USB Slave Controller is a single chip USB peripheral device that interfaces to microprocessors. The SL811S/T USB Controller incorporates USB Serial Interface functionality along with internal drivers and receivers that connect directly to the USB interface connector. The SL811S/T supports and operates in USB full speed mode, at 12 Mbits per second and in USB Slow speed mode at 1.5 Mbits per second.

The local host interface provides an 8-bit data path, with interrupt and DMA support to allow an easy interface to standard microprocessors or microcontrollers. Internally, the SL811S/T contains a 256-byte RAM data buffer. The RAM contains both control registers and data buffers. SL811S/T comes in two packages - 28-pin PLCC (SL811S) and 48-pin LPQFP (SL811T). Both products require a 3.3 VDC power supply.

The SL811S/T can interface to any microprocessor, microcontroller, or DSP. It can also interface directly to a variety of buses including ISA, PCMCIA and others through its 8-bit bidirectional Data port and through the following control signals - CS, WR, RD, INTR, and A0. Both INTEL and MOTOROLA buses, and others like them, are supported.

The SL811S/T USB Slave Controller is designed to conform to USB specification 1.1 for full-speed, and low speed operation. The USB specification should be referred to as a reference when designing with the SL811S/T.
