PD78P368A
16/8 BIT SINGLE-CHIP MICROCOMPUTER
The
m
PD78P368A is produced by replacing the internal mask ROM of the
m
PD78366A with a one-time PROM
or EPROM. One-time PROM products, in which data can be written once are effective for manufacture of small
quantities of multiple products and early stage start-up of application. EPROM products, to which programs can
be re-written after previously written programs have been erased, are suited for system evaluation.
The following user's manual describes the details of functions. Be sure to read it before design.
