8-BIT SINGLE-CHIP MICROCONTROLLER
The information in this document is subject to change without notice.
DESCRIPTION
The
μ
PD78064B(A) is an 8-bit single-chip microcontroller belonging to the
μ
PD78064B 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
μ
PD78064B, which is classified as standard grade.
The EMI (Electro Magnetic Interference) noise generated inside the
μ
PD78064B(A) is reduced compared to the
μ
PD78064 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.
