MOS INTEGRATED CIRCUIT
µPD75P4308
4-BIT SINGLE-CHIP MICROCONTROLLER
The µPD75P4308 replaces the µPD754304’s internal mask ROM with a one-time PROM and features expanded
ROM capacity.
Because the µPD75P4308 supports programming by users, it is suitable for use in prototype testing for system
development using the µPD754302 and 754304 products, and for use in small-lot production.
Detailed descriptions of functions are provided in the following document. Be sure to read the document
before designing.
µPD754304 User’s Manual: U10123E
FEATURES
• Compatible with µPD754304
• Memory capacity:
· PROM : 8192 × 8 bits
· RAM : 256 × 4 bits
• Can operate in the same power supply voltage as the mask version µPD754304
· VDD = 1.8 to 5.5 V
• Adopts a compact shrink SOP package
