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.
