PRELIMINARY PRODUCT INFORMATION
MOS INTEGRATED CIRCUIT
mPD78P018F
8-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The mPD78P018F is an 8-bit single-chip microcomputer which incorporates one-time PROM which can be written
to once only, or EPROM to which programs can be written, erased and rewritten.
www.DataSAhseteht4eUm.cPoDm78P018F is user-programmable, it is suitable for evaluation in system development, and for short-run
and multiple device-production, and early start-up.
This document should be read in conjunction with documentation on the mask ROM products.
FEATURES
Ý Pin compatible with mask ROM products (except VPP pin)
Ý Internal PROM: 60K bytes*1
Ý Internal high-speed RAM: 1024 bytes*1
Ý Internal expansion RAM : 1024 bytes*2
Ý Buffer RAM: 32 bytes
Ý Operable over same supply voltage range as mask ROM product (2.0 to 6.0 V)
* 1. The internal PROM and internal high-speed RAM size can be changed by means of the memory size switching
register.
2. The capacity of the internal expansion RAM can be changed by means of the internal expansion RAM
switching register.
Differences from mask ROM products are as follows:
• The same memory mapping as on a mask ROM product is possible by setting the memory
size switching register and the internal expansion RAM switching register.
• There is no function for incorporating pull-up resistors by means of a mask option.
In this document, the common parts of the one-time PROM product and EPROM product are represented by PROM.
The information contained in this document is being issued in advance of the production cycle for the
device. The parameters for the device may change before final production or NEC Corporation, at its
own discretion, may withdraw the device prior to its production.
Document No.

1. DIFFERENCES BETWEEN mPD78P018F AND MASK ROM PRODUCT
The mPD78P018F incorporates one-time PROM which can be written to once only, or EPROM to which programs
can be written, erased and rewritten.
By setting the memory size switching register and internal expansion RAM switching register it is possible to
make the functions of this device, except for the PROM specification and mask option for pins P60 to P63, identical
to those of a mask ROM product.
The differences between the mPD78P018F and mask ROM products are shown in Table 1-1.

Note
1. In the mPD78P018F, the capacity of the internal PROM and internal high-speed RAM can be changed by
means of the memory size switching register.
After RESET input, the internal PROM capacity is 60K bytes, and the internal high-speed RAM capacity
is 1K bytes.
2. In the mPD78P018F, the capacity of the internal expansion RAM can be changed by means of the internal
expansion RAM switching register.
The internal expansion RAM is set to 1K bytes by means of RESET input.
