µ
PD78P322
16/8-BIT SINGLE-CHIP MICROCONTROLLER
The
µ
PD78P322 is a version provided by replacing the
µ
PD75322's internal mask ROM with one-time PROM
or EPROM.
Because the one-time PROM version is programmable only once by users, it is ideally suited for small-scale
production of many different products, and rapid development and time-to-market of application sets.
The EPROM version is reprogrammable, and suited for the evaluation of systems.
The
µ
PD78P322K, which is the EPROM version, does not maintain planned reliability when
used in mass-produced products. Please use only experimentally or for evaluating functions
during trial manufacture.
Functions are described in detail in the following user's manual. Be sure to read it for designing.

FEATURES
•
µ
PD78322 compatible
• For mass-production, the
µ
PD78P322 can be replaced with the
µ
PD78322 which incorporates mask
ROM
•
Internal PROM: 16,384
×
8 bits
• Programmable once only (one-time PROM version without window)

µ
PD27C256A compatible
The
µ
PD78P328 is a QTOP
TM
microcontroller
Remark
QTOP microcontroller is a general term for microcontrollers which incorporate one-time PROM, and
are totally supported by NEC's programming service (from programming to marking, screening, and
verification).
