DESCRIPTION
The
μ
PD78076Y and 78078Y add the I
2
C bus control function to the
μ
PD78076 and 78078, and are suitable
for application in AV products.
Besides a high-speed, high-performance CPU, these microcontrollers have internal 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.
A one-time PROM version and an EPROM version (common name:
μ
PD78P078Y), both of which can operate
in the same power supply voltage range as the mask ROM version, and various development tools are also
available.
The details of the functions are described in the following user’s manuals. Be sure to read them before designing.
