2 / 38 page MB89820 Series 2 (Continued) • Three types of timers 8-bit PWM timer (also usable as a reload timer) 8-bit pulse width count timer (also usable as a reload timer) 20-bit time-base timer • Two serial interfaces 8-bit synchronous serial interface (Switchable transfer direction allows communication with various equipment.) UART (5-, 7-, 8-bit transfer capable) • External interrupt : 2 channels Capable of wake-up from low-power consumption modes (with an edge detection function) • Low-power consumption modes Stop mode (Oscillation stops to minimize the current consumption.) Sleep mode (The CPU stops to reduce the current consumption to approx. 1/3 of normal.) s s s s PRODUCT LINEUP (Continued) MB89823R MB89825 MB89P825 MB89PV820 Classification Mass production product (mask ROM products) One-time PROM product Piggyback/ evaluation product for evaluation and development ROM size 4 K × 8 bits (internal mask ROM) 8 K × 8 bits (internal mask ROM) 16 K × 8 bits (internal mask ROM) 16 K × 8 bits (internal PROM, programming with general- purpose EPROM programmer) 32 K × 8 bits (external ROM) RAM size 128 × 8 bits 256 × 8 bits 1024 × 8 bits CPU functions Number of instructions: 136 Instruction bit length: 8 bits Instruction length: 1 to 3 bytes Data bit length: 1, 8, 16 bits Minimum execution time: 0.8 µs/5 MHz (VCC = 5.0 V) Interrupt processing time: 7.2 µs/5 MHz (VCC = 5.0 V) Ports I/O ports (N-ch open-drain): 16 (All also serve as segment pins.)*1 I/O ports (N-ch open-drain): 6 I/O ports (CMOS): 6 (5 ports also serve as peripheral I/O.)
