µPD784214A, 784215A, 784216A, 784217A, 784218A, 784214AY, 784215AY, 784216AY, 784217AY, 784218AY
16-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD784214A, 784215A, 784216A, 784217A, and 784218A are products of the µPD784216A/784218A
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 µPD784214AY, 784215AY, 784216AY, 784217AY, and 784218AY are based on the µPD784216Y/784218Y
Subseries with the addition of a multimaster-supporting I2C bus interface.
The µPD78F4218A and 78F4218AY, products with a flash memory instead of the internal ROM of mask ROM
versions, and various development tools are also available.
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
