: LC865616A 16384 × 8 bits
: LC865612A 12288 × 8 bits
: LC865608A 8192 × 8 bits
(2) Random Access Memory (RAM) : LC865632A/28A/24A 640 × 8 bits
: LC865620A/16A/12A/08A 512 × 8 bits
(3) Bus Cycle Time / Instruction Cycle Time
The LC865632A/28A/24A/20A/16A/12A/08A 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 microcontrollers
(LC66000 series). Bus cycle time indicates the speed to read ROM.

Description

The LC865612A microcontrollers are 8-bit single chip microcontrollers with the following
on-chip functional blocks :
- CPU : Operable at a minimum bus cycle time of 0.5s (microsecond)
- On-chip ROM maximum capacity : 32K bytes
- On-chip RAM capacity : 640 bytes (LC865632A/28A/24A)
: 512 bytes (LC865620A/16A/12A/08A)
- 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 system
All of the above functions are fabricated on a single chip.
