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.
