Overview

The LC877C00 series are an 8-bit single chip microcontroller with the following on-chip functional blocks. :

• CPU: operable at a minimum bus cycle time of 83.3ns

• On-chip 64K-24K bytes ROM

• On-chip RAM: 2048/1536 bytes

• LCD controller / driver

• 16 bit timer/counters (can be divided into 8-bit units)

• 16 bit timer / PWM (can be divided into two 8-bit timers)

• Four 8-bit timer with prescalers

• Timer for use as date / time clock

• Synchronous serial I/O port (with automatic block transmit / receive function)

• Asynchronous / synchronous serial I/O port

• 2 channel 12bit PWM

• 12-channel × 8-bit AD converter

• High-speed clock counter
