DATA SHEET

DESCRIPTION

The

µPD78P058F is an Electro Magnetic Interference (EMI) noise reduction version of the µPD78P058.

The

µPD78P058F is a member of the µPD78058F Subseries of the 78K/0 Series, in which the on-chip mask ROM

of the

µPD78058F is replaced with one-time programmable (OTP) ROM.

Because this device can be programmed by users, it is suited for applications involving the small-scale production

of many different products, and for rapid development and time-to-market of new products.

Details are given in the following User’s Manuals. Be sure to read them before starting design.

µPD78058F, 78058FY Subseries User’s Manual : U12068E

78K/0 Series User’s Manual Instructions

: U12326E

FEATURES

• EMI noise reduction version (overall peak level reduced by 5 to 10 dB)

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

• Internal PROM : 60 KbytesNote 1

Programmable once only (ideal for small-scale production)

• Internal high-speed RAM : 1024 bytes

• Internal expansion RAM : 1024 bytesNote 2

• Buffer RAM : 32 bytes

• Operable in the same supply voltage range as mask ROM versions (VDD = 2.7 to 6.0 V)

• One of the QTOPTM Microcontrollers

Notes

1. The internal PROM capacity can be changed with the memory size switching register (IMS).

2. The internal expansion RAM capacity can be changed with the internal expansion RAM size switching

Remarks 1. For the difference between PROM and mask ROM versions, see 1. DIFFERENCES BETWEEN

µPD78P058F AND MASK ROM VERSIONS.

2. QTOP Microcontroller is the general name of the microcontrollers with on-chip one-time PROM that are

totally supported by the NEC writing service (from writing to marking, screening and testing).
