1996
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.

FEATURES
Compatible with the
m
PD78366A
Can be replaced with the
m
PD78366A containing mask ROM on a full-production basis.
Internal PROM: 48K bytes
Data can be written once (one-time PROM product without an erasure window)
Written data can be erased by exposure to ultraviolet light and re-written electrically (EPROM product with an
erasure window)
