Features

(1) Read-Only Memory (ROM) : LC865520A 20480 × 8 bits : LC865516A 16384 × 8 bits : LC865512A 12288 × 8 bits : LC865508A 8192 × 8 bits : LC865504A 4096 × 8 bits (2) Random Access Memory (RAM) : LC865520A/16A/12A/08A/04A 512 × 8 bits (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. Bus cycle time Cycle time Clock divider 1/1 1/2 1/.
