DATA SHEET
MOS INTEGRATED CIRCUIT
mPD78P368A
16/8 BIT SINGLE-CHIP MICROCOMPUTER
The mPD78P368A is produced by replacing the internal mask ROM of the mPD78366A with a one-time PROM
or EPROM. One-time PROM products, in which data can be written once are effective for manufacture of small
quantities of multiple products and early stage start-up of application. EPROM products, to which programs can
be re-written after previously written programs have been erased, are suited for system evaluation.
The following user's manual describes the details of functions. Be sure to read it before design.
mPD78366A User's Manual, Hardware: U10205E
mPD78356 User's Manual, Instructions: IEU-1395
FEATURES
• Compatible with the mPD78366A
• Can be replaced with the mPD78366A containing mask ROM on a full-production basis.
• Internal PROM: 48K bytes
• Data can be written once (one-time PROM product without an erasure window)
• Written data can be erased by exposure to ultraviolet light and re-written electrically (EPROM product with an
erasure window)
• PROM programming characteristics: Compatible with the mPD27C1001A
• QTOPTM microcomputer
Remark The QTOP microcomputer is a single-chip microcomputer with a built-in one-time PROM that is totally
supported by NEC. The support includes writing application programs, marking, screening, and
verification.
