4.0 Introduction
4.1 Block Diagram
The SL811HS is an Embedded USB Host/Slave Controller capable of communicate with either full-speed or low-speed USB
peripherals. The SL811HS can interface to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of
buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1.
The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed trans-
ceivers. The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode.
The SL811HS 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. Inter-
nally, the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer.
The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages
operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.

4.2 SL811HS Host or Slave Mode Selection [Master/Slave Mode]
SL811HS can work in two modes—host or slave. For slave-mode operation and specification, please refer to the SL811S
specification. This data sheet only covers host-mode operation.
