LC865520A/16A/12A/08A/04A

8-Bit Single Chip Microcontroller with On-Chip

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

Preliminary

Overview

The LC865520A/16A/12A/08A/04A microcontrollers are 8-bit single chip microcontrollers with the following one-chip

functional blocks:

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

- On-chip ROM Maximum Capacity : 20K bytes

- On-chip RAM Capacity : 512 bytes (LC865520A/16A/12A/08A/04A)

- 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

- 13-source 10-vectored interrupt system80

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

(3) Bus Cycle Time/Instruction Cycle Time

The LC865520A/16A/12A/08A/04A are constructed to read ROM twice within one instruction cycle. It has 1.7

times more performance capability within the same instruction cycle compared to our 4-bit microcomputers

(LC66000 series).

Bus cycle time indicates the speed to read ROM.
