DATA SHEET

MOS INTEGRATED CIRCUIT

PD75P0076

4-BIT SINGLE-CHIP MICROCONTROLLER

The

PD75P0076 replaces the

PD750068’s internal mask ROM with a one-time PROM and features expanded ROM

capacity.

Because the

PD75P0076 supports programming by users, it is suitable for use in prototype testing for system

development using the

PD750064, 750066, and 750068 products, and for use in small-lot production.

Detailed information about function is provided in the following user’s manual.

Be sure to read it before designing:

PD750068 User’s Manual: U10670E

FEATURES

Compatible with

PD750068

Memory capacity:

• PROM : 16384 x 8 bits

• RAM

: 512 x 4 bits

Can operate with same power supply voltage as the mask ROM version

PD750068

= 1.8 to 5.5 V

On-chip A/D converter capable of low-voltage operation (AV

REF

= 1.8 to 5.5 V)

8-bit resolution x 8 channels

Small shrink SOP package
