Product Summary

The SL811HST-AXC is an Embedded USB Host/Slave Controller capable of communicating in either full speed or low speed. The SL811HST-AXC interfaces to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HST-AXC USB Host Controller conforms to USB Specification 1.1. The SL811HST-AXC 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.
