.D8-Bit Single Chip Usb(Full-speed) Microcontroller with on-chip 64KB FLASH-ROM and 3072 byte RAM.
wwwOverview
The LC87F5664A microcomputer is 8-bit single chip Usb microcomputer with the following on-chip functional
blocks:
m- CPU: Operable at a minimum bus cycle time of 83ns
- 64K bytes flash ROM (re-writeable on board)
o- 3072 byte RAM
.c- two high performance 16 bit timer/counters (can be divided into 8 bit units)
- four 8 bit timers with prescalers
- timer for use as date/time clock
U- one synchronous serial I/O ports (with automatic block transmit/receive function)
- one asynchronous/synchronous serial I/O port
t4- PWM × 2
- 8-channel × 8-bit AD converter
e- usb serial bus interface engine (conforms to USB Specification, Version 1.1)
