PD78064B(A)
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
µPD78064B(A)
is an 8-bit single-chip microcontroller belonging to the
µPD78064B
subseries of the 78K/0
series. A stricter quality assurance program is applied to this device, which is classified as special grade, compared
to the
µPD78064B,
which is classified as standard grade.
The EMI (Electro Magnetic Interference) noise generated inside the
µPD78064B(A)
is reduced compared to the
µPD78064
subseries.
A one-time PROM version that can operate in the same power supply voltage as the mask ROM version, and various
development tools are available for this device.
For detailed descriptions of functions, refer to the following user’s manuals. Be sure to read them before
starting design.
