µPD78P014

8-BIT SINGLE-CHIP MICROCOMPUTER

DESCRIPTION

The µPD78P014 is a member of the µPD78014 subseries of 78K/0 series products. It uses a one-time-programmable

(OTP) ROM or EPROM instead of the mask ROM of the µPD78014.

Because the µPD78P014 can be programmed by users, it is ideally suited for applications involving the evaluation

ofsystemsindevelopmentstages,small-scaleproductionofmanydifferentproducts,andrapiddevelopmentandtime-

to-market of a new product.

Detailed information about product features and specifications can be found in the following document. Please

make sure to read this document before starting design.

µPD78014, 78014Y Series User’s Manual : IEU-1343

FEATURES

• Pin compatible with mask ROM versions (except VPP pin)

• Internal PROM: 32K bytes^Note

• µPD78P014DW

: Reprogrammable (ideal for system evaluation)

• µPD78P014CW, 78P014GC-AB8 : Programmable once only (ideal for small-scale production)

• Internal high-speed RAM: 1024 bytes^Note

• Buffer RAM: 32 bytes

• Operable over same supply voltage range as mask ROM version (2.7 to 6.0 V)

• Available for the QTOP^TMmicrocomputer

Note The internal PROM and internal high-speed RAM size can be set by means of the memory size switching

Remark The QTOP microcomputer is the general term for a single-chip microcomputer with on-chip one-time

PROM. NEC supports its program writing, marking, screening, and verification.

Differences from mask ROM versions are as follows:

• The same memory mapping as on a mask ROM version is possible by setting the memory size

switching register.

• There is no function for incorporating pull-up resistors by means of a mask option in P60 to P63

pins.
