FEATURES
Four endpoints (CONTROL, INTERRUPT, BULK-
IN and BULK-OUT) are implemented
FIFO in each of IN and OUT endpoint is to support
maximum bulk size (64 bytes)
Embedded microcontroller is responsible for
executing USB and device dependent commands
Hardware driven interrupt improves latency and
efficiency
16K x 14 internal metal programmable ROM to
meet various application demand
Accessible external memory provATAs viable
development tool
Built-in USB transceiver
4MHz crystal input with internal 12X
multiplierOptional serial EEPROM to store
customized data
3.3 Volt power with 5 Volt tolerant I/O
Low power with 0.35
m technology
100-pin LQFP package
The CS8810 is a single chip general-purpose USB
controller, which integrates USB 1.1 compliant
transceiver. Together with product dependent
firmware and software driver, this chip is able to fulfill
diverse demand of end products.
