DESCRIPTION
The
m
PD78P064 is a product of
m
PD78064 subseries in 78K/0 series, in which the on-chip mask ROM of the
m
PD78064
is replaced by one-time PROM or EPROM.
As program write by user is possible, the
m
PD78P064 is best suited for evaluation, short-run and multiple-device
production, and early rise upon system development.
Functions are described in detail in the following User’s Manuals, which should be read when carrying out
design work.

FEATURES
Pin compatible with mask ROM products (except the V
PP
pin)
Internal PROM: 32K bytes
Note

m
PD78P064GC, 78P064GF: Programmable once only (ideal for small-scale production)
Internal high-speed RAM: 1024 bytes
Note

￥
4 bits
Operable in the same supply voltage as mask ROM products (V
DD
= 2.0 to 6.0 V)
Corresponding to QTOP
TM
microcomputers
: Reprogrammable (ideal for system evaluation)
Note
Internal PROM and internal high-speed RAM capacities can be changed by memory size switching register (IMS).
Remarks 1.
For the differences between PROM products and mask ROM products, refer to
1. DIFFERENCES
BETWEEN
m
PD78P064 AND MASK ROM PRODUCTS
.
A QTOP microcontroller is the general name for a single-chip microcontroller with one-time PROM for
which program writing, marking, screening, and verifying are completely supported by NEC.
