PD78P064B
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
碌
PD78P064B is a product of
碌
PD78064B subseries in 78K/0 series, in which the on-chip mask ROM of the
碌
PD78064B is replaced by one-time PROM.
As program write by user is possible, the
碌
PD78P064B 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鈥檚 Manuals, which should be read when carrying out
design work.
