DATA SHEET

MOS INTEGRATED CIRCUIT

µPD75P068

4 BIT SINGLE-CHIP MICROCOMPUTER

The µPD75P068 is produced by replacing the internal mask ROM of the µPD75068 with a one-time PROM

in which data can be written once.

The following user's manual describes the details of the functions of the µPD75P068. Be sure to read it

before designing an application system.

µPD75068 User's Manual: IEU-1366

FEATURES

•

Compatible with the µPD75068

Can be replaced with the µPD75068 containing mask ROM on a full-production basis.

•

Internal one-time PROM: 8064 words × 8 bits

Internal RAM: 512 words × 4 bits

Internal pull-up resistors can be specified with software: Ports 0 to 3 and 6

N-ch open-drain input-output: Ports 4 and 5

Can operate at low voltage: VDD = 2.7 to 6.0 V
