Product Summary

The SL811HS is a microprocessor interface. The SL811HS 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. 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.

Parametrics

SL811HS absolute maximum ratings: (1)Storage Temperature: –40 to 125℃; (2)Voltage on any pin with respect to ground: –0.3V to 6.0V; (3)Power Supply Voltage (VDD): 4.0 V; (4)Power Supply Voltage (VDD1): 4.0 V; (5)Lead Temperature (10 seconds): 180℃.

Features

SL811HS features: (1)The only USB Host/Slave controller for embedded systems in the market with a standard microprocessor bus interface; (2)Supports both full-speed (12 Mbps) and low-speed (1.5 Mbps) USB transfer.
