Preliminary

Overview

The LC875032A/24A/16A microcontroller is 8-bit single chip microcontroller with the following on-chip functional blocks:

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

- 32K/24K/16K bytes ROM

- 640 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

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

- one asynchronous/synchronous serial I/O port

- 12-bit PWM

× 2

- 3-channel

× 8-bit AD converter

- high speed 8-bit parallel interface

- 16-source 10-vectored interrupt system

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