MOS INTEGRATED CIRCUIT

µPD78P324, 78P324(A)

16-/8-Bit Single-Chip Microcomputers

The µPD78P324 is a product in which the µPD78324’s internal mask ROM is replaced by a one-time PROM

or EPROM. The one-time PROM product, which enables writing only once, is effective for multiple-device

small production of sets or early start of mass-production. The EPROM product, which enables program

writing, deletion, and rewriting, is the most suitable for system evaluation.

The µPD78P324(A) is more reliable than the µPD78P324. The µPD78P324(A) is a product resulting from

the µPD78324(A) whose internal mask ROM is replaced by a one-time PROM.

For details of functions, please refer to the following User’s Manual. Reading this manual is indispensable

especially for designing work.

µPD78322 User’s Manual: IEU-1248

FEATURES

● µPD78324 compatible

• For mass-production, this can be replaced by the µPD78324 incorporated in the mask ROM.

● Minimum instruction run time: 250 ns (with the external clock operating at 16 MHz): µPD78P324 & 78P324(A)

320 ns (with the external clock operating at 12.5 MHz): µPD78P324(A1) &

78P324(A2)

● Internal PROM: 32768 x 8 bits

• Writing enabled only once (windowless one-time PROM product)

• Elimination by ultraviolet light and electrical rewriting enabled (EPROM product with window): µPD78P324

only

● ECC circuit incorporated

• High internal PROM content reliablility possible

● PROM programming characteristic: µPD27C1001A compatible

● QTOP^TMmicrocomputer compatible

Remark

A QTOP microcomputer is a single-chip microcomputer with one-time PROM for which program

writing, marking, screening, and verifying is completely supported by NEC.

APPLICATION FIELDS

● µPD78P324: Fields dealing with motor control equipment.

● µPD78P324(A), 78P324(A1), and 78P324(A2): Automotive and transportation equipments, etc.

Thisdocumentdescribesthe µPD78P324, 78P324(A), µPD78P324(A1), andµPD78P324(A2)aswell. However,

unless there are particular differences, the µPD78P324 is described as a representative product. PROM is

the representative term used for the part common to both the one-time PROM product and the EPROM

product.
