DATA SHEET
DESCRIPTION
The
μ
PD78P058FY is an Electro Magnetic Interference (EMI) noise reduction version of the
μ
PD78P058Y.
The
μ
PD78P058FY is a member of the
μ
PD78058FY Subseries of the 78K/0 Series, in which the on-chip mask
ROM of the
μ
PD78058FY 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.

FEATURES
EMI noise reduction version (overall peak level reduced by 5 to 10 dB)
Pin compatible with mask ROM versions (except the V
PP
pin)
Internal PROM : 60 Kbytes
Note 1
Programmable once only (ideal for small-scale production)
Internal high-speed RAM : 1024 bytes
Internal expansion RAM : 1024 bytes
Note 2
Buffer RAM : 32 bytes
Connectable I
2
C bus interface
Operable in the same supply voltage range as mask ROM versions (V
DD
= 2.7 to 6.0 V)
One of the QTOP
TM
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
μ
PD78P058FY 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).
