ELECTRON DEVICE

µPD75238

4 BIT SINGLE-CHIP MICROCOMPUTER

The µPD75238 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 µPD75217, the µPD75238 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 µPD75238 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 µPD75238, the µPD75P238, 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.

FEATURES

• Mass-storage built-in ROM and RAM

• 8-bit A/D converter: 8 channels

• Program memory (ROM) : 32K × 8

• Enhanced timer/counter function: 5 channels

• 8-bit serial interface: 2 channels

• Data memory (RAM)

: 1K × 4

• I/O port: 64 lines (excluding pins dedicated

to FIP)

• Application-oriented interrupt functions

• PROM version device: µPD75P238

• Minimum instruction execution time:

0.67 µs (at 6.0 MHz)

• Instructionexecutiontimespecificationfunc-

tion to allow a wide range of operating

voltages

• ProgrammableFIPcontroller/drivercontained

• Number of segments: 9 to 24 segments

• Number of digits

: 9 to 16 digits
