MB89PV870

The MB89PV870 is a line of single-chip microcontrollers. In addition to a compact instruction set, the microcontrollers contain a variety of peripheral functions such as dual-clock control system, five operating speed control stages, timers, a PWM timer, a serial interface, an A/D converter, an external interrupt, an LCD controller/driver, and a watch prescaler.

The features of the MB89PV870 are: (1)F2MC-8L family CPU core; (2)Dual-clock control system; (3)Maximum memory space: 64 Kbytes; (4)Minimum execution time: 0.4 s/10 MHz; (5)Interrupt processing time: 3.6 s/10 MHz; (6)I/O ports: max. 45 channels; (7)21-bit timebase timer; (8)8-bit PWM timer: 1 channel, 1 output channel; (9)8/16-bit timer/counter: 2 channels (16 bits * 1 channel); (10)8-bit serial I/O: 1 channel; (11)10-bit A/D converter: 8 channels; (12)OP amp: 4 channels; (13)External interrupt (wake-up function): 8 channels.

The absolute maximum ratings of the MB89PV870 are: (1)Power supply voltage: VSS 0.3V min and VSS + 7.0 V max; (2)A/D converter reference input voltage: VSS 0.3V min and VSS + 7.0 V max; (3)LCD power supply voltage: VSS 0.3 V min and VSS + 7.0 V max; (4)Input voltage: VSS 0.3 V min and VCC + 0.3 V max; (5)Output voltage: VSS 0.3V min and VCC + 0.3 V max; (6)"L" level maximum output current: 20 mA; (7)"L" level average output current: 4mA; (8)"L" level total maximum output current: 100 mA; (9)"L" level total average output current: 40 mA; (10)"H" level maximum output current: 20 mA; (11)"H" level average output current: 4 mA.
