Ordering number : ENN- 6697 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 .. - 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. 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 pared to our 4-bit microputers (LC66000 series). Bus cycle time indicates the speed to read ROM.
