LC866432A/28A/24A/20A/16A/12A/08A
(3) Bus Cycle Time / Instruction Cycle Time
The LC866432A / 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.
