SL811S/T

The SL811S/T is designed as the USB dual speed slave controller which 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 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.

Features of the SL811S/T are:(1)conforms to USB specification 1.1;(2)standard microprocessor interface;(3)8-bit bidirectional data port,interfaces to any external bus or CPU (intel,motorola,etc.);(4)on-chip full/slow speed USB transceivers;(5)memory buffer includes double buffer ping pong operation scheme;(6)operates on either 12-MHz or 48-MHz crystal/clock;(7)auto address increment mode to simplify memory access and improve performance;(8)operates on either 12-MHz or 48-MHz crystal/clock;(9)generic WDM mini port driver for Windows 98, 2000/NT 5.0, and CE3.0, firmware and system USB demo source examples are available;(10)supports DMA transfers.
