DATA SHEET
The µ PD75P3116 replaces the µ PD753108’s internal mask ROM with a one-time PROM, and features expanded
ROM capacity.
Because the
µ PD75P3116 supports programming by users, it is suitable for use in evaluation of systems in the
development stage using the
µ 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:
µ PD753108 User’s Manual: U10890E
FEATURES
Compatible with µ PD753108
Memory capacity:
• PROM: 16384 ×8 bits
• RAM: 512 ×4 bits
Can be operated in same power supply voltage range as the mask version µ 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.
