DATA SHEET

The

PD75P3116 replaces the

PD753108’s internal mask ROM with a one-time PROM, and features expanded

ROM capacity.

Because the

PD75P3116 supports programming by users, it is suitable for use in evaluation of systems in the

development stage using the

PD753104, 753106, or 753108, and for use in small-scale production.

Detailed information about functions is provided in the following User’s Manual. Be sure to read it before

designing:

PD753108 User’s Manual: U10890E

FEATURES

Compatible with

PD753108

Memory capacity:

• PROM: 16384 ×8 bits

• RAM: 512 ×4 bits

Can be operated in same power supply voltage range as the mask version

PD753108

• VDD = 1.8 to 5.5 V

On-chip LCD controller/driver

QTOPTM microcontroller

Remark QTOP microcontrollers are microcontrollers with on-chip one-time PROM that are totally supported by NEC.

This support includes writing application programs, marking, screening, and verification.
