MOS INTEGRATED CIRCUIT
µPD75P3018A
4-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD75P3018A replaces the µPD753017A’s internal mask ROM with a one-time PROM, and features expanded
ROM capacity. The µPD75P3018A inherits the function of the µPD75P3018, and enables high-speed operation at
a low supply voltage of 1.8 V.
Because the µPD75P3018A supports programming by users, it is suitable for use in evaluation of systems in
development stages using the µPD753012A, 753016A, or 753017A, and for use in small-scale production.
The following document describes further details of the functions. Please make sure to read this document
before starting design.
µPD753017 User’s Manual : U11282E
FEATURES
Compatible with µPD753017A
Memory capacity:
• PROM : 32768 × 8 bits
• RAM : 1024 × 4 bits
Can operate in the same power supply voltage as the mask version µPD753017A
• VDD = 1.8 to 5.5 V
LCD controller/driver
