UPD75P238 - 4-BIT SINGLE CHIP MICROCOMPUTER

Datasheet Summary

Description

The µPD75P238 is a version of the µPD75238 in which the on-chip mask ROM is replaced by one-time PROM or EPROM.

The one-time PROM version can be written to once only, and is useful for short-run and multiple deviceproduction of sets and early start-up.

Features

o µPD75238 pin compatible o On-chip PROM: 32640 × 8 o On-chip RAM: 1024 × 4 o High-voltage display outputs . S0 to S8 & T0 to T9 : Internal pull-down resistors . S9, S16 to S23 & T10 to T15: Open-drain o Drive capability in same supply voltage range as mask version µPD75238 (2.7 to 6.0 V) o Ports 4 & 5: No pull-up resistor o Port 7: No pull-down resistor Note USE VCR, Audio-visual, ECR, Microwave oven No internal pull-up and pull-down resistor function by mask option.

DATA SHEET MOS INTEGRATED CIRCUIT µPD75P238 4-BIT SINGLE CHIP MICROCOMPUTER DESCRIPTION The µPD75P238 is a version of the µPD75238 in which the on-chip mask ROM is replaced by one-time PROM or EPROM. The one-time PROM version can be written to once only, and is useful for short-run and multiple deviceproduction of sets and early start-up. Also, the EPROM version allows programs to be written and rewritten, and is thus ideal for system evaluation. Functions are described in detail in the following User's Manual, which should be read when carrying out design work. µPD75238 User's Manual : IEU-731 The µPD75P238 EPROM product does not provide a level of reliability suitable for use as a volume production product for users' devices.
