PD784224, 784225, 784224Y, 784225Y
16/8-BIT SINGLE-CHIP MICROCONTROLLERS
The
µ
PD784224 and 784225 are products of the
µ
PD784225 Subseries in the 78K/IV Series. Besides a high-
speed and high performance CPU, these controllers have ROM, RAM, I/O ports, 8-bit resolution A/D and D/A
converters, timers, serial interfaces, a real-time output port, interrupt functions, and various other peripheral
hardware.
The
µ
PD784224Y and 784225Y are based on the
µ
PD784225 Subseries with the addition of a multimaster-
supporting I
2
C bus interface.
Flash memory versions, the
µ
PD78F4225 and 78F4225Y, which replace the internal ROM of the mask ROM
version with flash memory, and various development tools are also available.
The functions are explained in detail in the following user’s manuals. Be sure to read this manual when
designing your system.
