MOS INTEGRATED CIRCUIT
µPD78P4038
16/8-BIT SINGLE-CHIP MICROCONTROLLER
The µPD78P4038, 78K/IV Series' product, is a one-time PROM or EPROM version of the µPD784035, µPD784036,
µPD784037, and µPD784038 with internal masked ROM.
Since user programs can be written to PROM, this microcontroller is best suited for evaluation in system
development, manufacture of small quantities of multiple products, and fast start-up of applications.
For specific functions and other detailed information, consult the following user's manual.
This manual is required reading for design work.
