DESCRIPTION
The
μ
PD78074B and 78075B, which are members of the
μ
PD78075B Subseries of the 78K/0 Series, are ideal for
AV products.
Compared to the existing
μ
PD78074 and 78075, EMI (Electro Magnetic Interference) noise generated inside the
microcontroller is reduced.
Besides a high-speed, high-performance CPU, these microcontrollers have on-chip ROM, RAM, I/O ports, 8-bit
resolution A/D converter, 8-bit resolution D/A converter, timer, serial interface, real-time output port, interrupt control,
and various other peripheral hardware.
The
μ
PD78P078 including a one-time PROM version or an EPROM version can operate in the same power supply
voltage range as a mask ROM version, and various development tools are available.
The details of the functions are described in the following user’s manuals. Be sure to read the documents
before starting design.
