General Description

The µPD75236 is a microcomputer with a CPU capable of 1-, 4-, and 8-bit-wise data processing, a ROM, a RAM, I/O ports, a fluorescent display tube (FIP ®) controller/driver, A/D converters, 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.

The µPD75236 has the more improved peripheral functions including the RAM capacity, FIP controller/driver display capabilities, I/O ports, A/D converter and serial interface than those of the µ PD75216A.

The µPD75236 is most suited for advanced and popular VCR timer and tuner applications, single-chip configurations of system computers, advanced CD players and advanced microwave ovens.
