Overview

The LC875164A/48A/32A microcontroller is 8-bit single chip microcontroller with the following on-chip functional blocks:

- CPU: Operable at a minimum bus cycle time of 100ns

- 64K/48K/32K bytes ROM

- 1024 byte RAM

- two high performance 16 bit timer/counters (can be divided into 8 bit units)

- two 8 bit timers with prescalers

- timer for use as date/time clock

- two synchronous serial I/O ports (with automatic block transmit/receive function)

- one asynchronous/synchronous serial I/O port

- 12-bit PWM × 2

- 8-channel × 8-bit AD converter

- high speed 8-bit parallel interface

- 19-source 10-vectored interrupt system

All of the above functions are fabricated on a single chip.
