Overview

The LC876596B and LC876580B are 8 bit single chip microcontrollers with the following on-chip functional blocks :

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

- On-chip ROM Maximum Capacity : LC876596B 96K bytes

LC876580B 80K bytes

- On-chip RAM: 2048 bytes

- VFD automatic display controller / driver

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

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

- timer for use as date / time clock

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

- asynchronous / synchronous serial I/O port

- 12-channel × 8-bit AD converter

- Weak signal detector

- 15-source 10-vectored interrupt system

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