CMOS IC
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
www.DataSheet4U.com - 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.
