1 / 21 page 11901 RM (IM) Chigira No.6697-1/21 Ver.1.02 32300 Preliminary Overview The LC865520B/16B/12B/08B/04B are 8-bit single chip microcontrollers with the following one-chip features: - CPU : Operable at a minimum bus cycle time of 0.5 µs - On-chip ROM Capacity : 20K/16K/12K/8K/4K bytes - On-chip RAM Capacity : 512 bytes (LC865520B/16B/12B/08B/04B) - 16-bit timer/counter (can be divided into two 8 bit timers) - 16-bit timer/PWM (can be divided into two 8 bit timers) - 8-channel × 8-bit AD converter - Two 8-bit synchronous serial-interface circuits - 13-source 10-vectored interrupt system Features (1) Read Only Memory (ROM) : LC865520B 20480 × 8 bits : LC865516B 16384 × 8 bits : LC865512B 12288 × 8 bits : LC865508B 8192 × 8 bits : LC865504B 4096 × 8 bits (2) Random Access Memory (RAM) : LC865520B/16B/12B/08B/04B 512 × 8 bits (3) Bus Cycle Time/Instruction Cycle Time The LC865520B/16B/12B/08B/04B are constructed to read ROM twice within one instruction cycle. It has 1.7 times the performance capability for the same instruction cycle compared to our 4-bit microcontrollers (LC66000 series). Bus cycle time indicates the speed to read ROM. Bus cycle time Instruction cycle time Clock divider System clock oscillation Oscillation Frequency Voltage 0.5 µs 1 µs 1/1 Ceramic (CF) 6MHz 4.5V to 6.0V 2 µs 4 µs 1/2 Ceramic (CF) 3MHz 2.5V to 6.0V 7.5 µs 15 µs 1/2 Internal RC 800kHz 2.5V to 6.0V 183 µs 366 µs 1/2 Crystal (XTAL) 32.768kHz 2.5V to 6.0V 8-Bit Single Chip Microcontroller with On-Chip 20/16/12/08/04K-Byte ROM and 512-Byte RAM LC865520B/16B/12B/08B/04B Ordering number : ENN*6697 CMOS IC |
