Description
The µPD75212A is a microcomputer with a CPU capable of 1-, 4-, and 8-bit data processing, ROM, RAM, I/O ports, a fluorescent display tube controller/driver, a watch timer, a timer/pulse generator capable of outputting 14-bit PWM, a serial interface and a vectored interrupt function integrated on a single-chip.
Features
- Architecture equal to that of an 8-bit microcomputer High-speed operation : Minimum instruction execution time : 0.95 µs (when operated at 4.19 MHz) Instruction execution time variable function realizing a wide range of operating voltages On-chip large-capacity program memory : 12K bytes.
- Watch operation with an ultra low current consumption : 5 µA TYP. (at the 3 V operation).
- On-chip programmable fluorescent display tube controller/driv.
