Features (1) Read Only Memory (ROM) : LC865632A 32512 × 8 bits : LC865628A 28672 × 8 bits : LC865624A 24576 × 8 bits : LC865620A 20480 × 8 bits : 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. Bus cycle time cycle time System clock oscillation Oscillation Frequency Voltage 0.5 µs 1.0 µs Ceramic resonator oscillation 6MHz 4.5 - 6.0V 2.0 µs 4.0 µs Ceramic resonator oscillation 1.5MHz 2.5 - 6.0V 3.75 µs 7.5 µs RC resonator oscillation 800MHZ 2.5 - 6.0V 91.5 µs 183 µs Crystal oscillation 32.568kHz 2.5 - 6.0V 8-Bit Single Chip Microcontroller LC865632/28/24/20/16/12/08A Ordering number : ENN*6698 CMOS IC |
