PD78P328

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.

FEATURES

•

µ

PD78328 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:

• The µPD78P328 is a QTOP

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).

2. DIFFERENCES BETWEEN µPD78P328 and µPD78328

The µPD78P328 is a product provided by replacing the µPD78328's on-chip mask ROM with one-time PROM
or EPROM. Thus, the µPD78P328 and µPD78328 are the same in function except for the ROM specifications such
as write or verify. Table 2-1 lists the differences between these two products.

This Data Sheet describes the PROM specification function. Refer to the
other functions.

3. PROM PROGRAMMING

The PROM incorporated in the µPD78P328 is a 16,384 x 8-bit electrically writable PROM. For programming,

set the PROM programming mode by using the RESET and AVDD pins.

The programming characteristics are compatible with the µPD27C256A programming characteristics.

3.1 Operation Mode

To set the program write/verify mode, set RESET = H and AV

selected by setting the CE and OE pins, as listed in Table 3-2.

To read the PROM contents, set the read mode.
Connect the unused pins exactly as indicated on Pin Configuration.

DD = L. For the mode, the operation mode can be
