8-Bit Single Chip Microcontroller with On-Chip

20/16/12/08/04K-Byte ROM and 512-Byte RAM

Preliminary

Overview

The LC865520B/16B/12B/08B/04B are 8-bit single chip microcontrollers with the following one-chip features:

- CPU : Operable at a minimum bus cycle time of 0.5µs

- On-chip ROM Capacity : 20K/16K/12K/8K/4K bytes

- On-chip RAM Capacity : 512 bytes (LC865520B/16B/12B/08B/04B)

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

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

- 8-channel × 8-bit AD converter

- Two 8-bit synchronous serial-interface circuits

- 13-source 10-vectored interrupt system

(3) Bus Cycle Time/Instruction Cycle Time

The LC865520B/16B/12B/08B/04B are constructed to read ROM twice within one instruction cycle.

It has 1.7 times the performance capability for the same instruction cycle compared to our 4-bit

microcontrollers (LC66000 series).

Bus cycle time indicates the speed to read ROM.
