The SL811HS package is a 28-pin PLCC. The device requires 3.3 VDC. Average typical current consumption is less then 20 mA
for 3.3V.
SL811HS USB Host Controller Pins Description
Notes:
4.
5.
The A0 Address bit is used to access address or data registers in I/O-mapped or memory-mapped applications.
The CM Clock Multiplier pin should be tied HIGH for a 12-MHz clock source and tied to ground for a 48-MHz clock source. In SL11H, this pin was designated
as an ALE input pin.
V
can be derived from the USB supply. The diagram below shows a simple method to provide 3.3V/30 mA. Another option is to use a Torex Semiconductor,
Ltd. 3.3V SMD regulator (part number XC62HR3302MR).
The X1/X2 clock requires external 12- or 48-MHz matching crystal or clock source.

DMA Request
. An active LOW output used with an external DMA controller. nDRQ and
nDACK form the handshake for DMA data transfers. In host mode, pin must be left
unconnected in Host Mode.
Read Strobe Input
. An active LOW input used with nCS to Read registers/data memory.
