Overview

The LC866448B/44B/40B/36B/32B/28B/24B/20B/16B/12B/08B microcontrollers are 8-bit single chip microcontrollers

with the following on-chip functional blocks:

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

- On-chip ROM Maximum Capacity : 48K bytes

- On-chip RAM Capacity : 1152/768/640/512 bytes

(LC866448B/44B/40B/36B/32B/28B/24B/20B/16B/12B/08B)

- 16-bit timer /counter (or two 8-bit timers)

- 16-bit timer /PWM

(or two 8-bit timers)

- 8-channel

× 8-bit AD converter

- Two 8-bit synchronous serial-interface circuits (1-channel

× 16bit, 1-channel × 8bit)

- 14-source 10-vectored interrupt system

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