Overview

The LC877264A, LC877256A and LC877248A 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 : LC877264A 64K bytes

LC877256A 56K bytes

LC877248A 48K bytes

- On-chip RAM capacity: 2048 bytes

- LCD 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

- Small signal detector

- 14-source 10-vectored interrupt system

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