MOS INTEGRATED CIRCUIT

µPD75P048

4-BIT SINGLE-CHIP MICROCOMPUTER

DESCRIPTION

The µPD75P048 is a One-Time PROM version of the µPD75048. The µPD75P048 is suitable for small-scale

production or experimental production in system development.

Detailed functions are described in the following user’s manual. Read this manual when designing your

system.

µPD75048 User’s Manual: IEU-1278

FEATURES

• The µPD75048 compatible

•

The µPD75P048 for evaluation/pre-production, while the µPD75048 for mass-production

• 8064 × 8 bits of one-time programmable ROM

• 512 × 4 bits of RAM

• 1024 × 4 bits of EEPROM (Data memory area)

• Ports 0 to 3 and 6 to 8 with software-selectable pull-up resistors

• Port 9 with software-selectable pull-down resistors

• 12 N-channel open drain input/output ports (ports 4, 5, and 10)

• Low-voltage operation possible (VDD = 2.7 to 6.0 V)
