DATA SHEET
MOS Integrated Circuit
µPD78P328
16/8-BIT SINGLE-CHIP MICROCONTROLLER
The µPD78P328 is a product provided by replacing the µPD75328's internal mask ROM with one-time
PROM or EPROM.
The one-time PROM version is programmable only once and is useful for small-lot production of many
different products and early development and time-to-market of application sets.
The EPROM version is reprogrammable, and suited for the evaluation of systems.
Functions are described in detail in the following user's manual. Be sure to read it before designing.
µPD78328 User's Manual: IEU-1268
FEATURES
• µPD78328 compatible
• For mass-production, the µPD78P328 can be replaced with the µPD78328 incorporating mask ROM
• Internal PROM: 16,384 x 8 bits
• Programmable once only (one-time PROM version without window)
• Erasable with ultraviolet rays and electrically programmable (EPROM version with window)
• PROM programming characteristics: µPD27C256A compatible
• The µPD78P328 is a QTOPTM microcontroller.
Remark QTOP microcontroller is a general term for microcontrollers which incorporates one-time PROM, and
are totally supported by NEC's programming service (from programming to marking, screening, and
verification).
