PD75238

4 BIT SINGLE-CHIP MICROCOMPUTER

The

碌

PD75238 is a single-chip microcomputer which contains a CPU capable of 1-, 4-, and 8-bit data

processing, ROM, RAM, and I/O ports. In addition, it contains a fluorescent display tube (FIP

;

) controller/driver,

A/D converter, clock timer, timer/pulse generator capable of 14-bit PWM output, serial interface, and vectored

interrupt function.

In comparison with the

碌

PD75217, the

碌

PD75238 has larger ROM and RAM capacity and has been enhanced

in such peripheral facilities as the display function of the FIP controller/driver, I/O ports, A/D converter, serial

interface.

The

碌

PD75238 finds best use in such applications as timer/tuner of VCRs from advanced type to common

type, configuration of one-chip system control microcomputer, advanced CD player, advanced microwave

ovens, etc.

With the

碌

PD75238, the

碌

PD75P238, which is a PROM product, and various development tools including

IE-75001-R and assemblers are available. They can be used for evaluation during system development and

small-volume production.
