16-BIT SINGLE-CHIP MICROCONTROLLER

The μPD784907 and μPD784908 are products of the μPD784908 Subseries in the 78K/IV Series. These products contain various peripheral hardware such as IEBusTM controller, ROM, RAM, I/O ports, 8-bit resolution A/D, timers, serial interface, and interrupt functions, as well as a high-speed, high-performance CPU.

In addition, the μPD78P4908 (one-time PROM product), which is used to evaluate the functions of mask ROM versions, and development tools are also available.
