DATA SHEET
MOS INTEGRATED CIRCUIT
µPD784218, 784218Y
16-/8-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The µPD784218 is a member of the µPD784218 Subseries of the 78K/IV Series. In addition to a high-speed and
high-performance CPU, the µPD784218 incorporates a variety of peripheral hardware such as ROM, RAM, I/O ports,
8-bit resolution A/D and D/A converters, timers, serial interfaces, real-time output ports, and an interrupt function.
The µPD784218YNote is the µPD784218 Subseries with a multi-master supporting I2C bus interface added.
Flash memory versions, the µPD78F4218 and 78F4218Y, which can operate in the same voltage range as the
mask ROM versions, and various development tools are also available.
Note Under development
Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before
designing.
