µPD78P058F
8-BIT SINGLE-CHIP MICROCONTROLLER
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
register (IXS).
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).

1. DIFFERENCES BETWEEN µPD78P058F AND MASK ROM VERSIONS
The µPD78P058F is a single-chip microcontroller with an on-chip one-time PROM.
Setting the memory size switching register (IMS) and internal expansion RAM size switching register (IXS) enables
identical functions to mask ROM versions (µPD78056F and 78058F) except the functions of PROM specifications and
of mask options for P60 to P63.
Differences between the µPD78P058F and mask ROM versions are shown in Table 1-1.

Note The RESET input sets the internal PROM capacity and internal expansion RAM capacity to 60 Kbytes and 1024
bytes, respectively.
Caution
The PROM version and mask ROM version differ in noise tolerance and noise emission. When
replacing a PROM version with a mask ROM version when switching from experimental production
to mass production, make a thorough evaluation with a CS version (not ES version) of the mask
ROM version.
