PD78P058F
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
碌
PD78P058F is an Electro Magnetic Interference (EMI) noise reduction version of the
碌
PD78P058.
The
碌
PD78P058F is a member of the
碌
PD78058F Subseries of the 78K/0 Series, in which the on-chip mask ROM
of the
碌
PD78058F 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鈥檚 Manuals. Be sure to read them before starting design.

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
碌
PD78P058F 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).
