µ
PD75P0076
4-BIT SINGLE-CHIP MICROCONTROLLER
The
µ
PD75P0076 replaces the
µ
PD750068’s internal mask ROM with a one-time PROM and features expanded ROM
capacity.
Because the
µ
PD75P0076 supports programming by users, it is suitable for use in prototype testing for system
development using the
µ
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:
