MOS INTEGRATED CIRCUIT
µPD784907, 784908
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.
Detailed function descriptions are provided in the following user's manuals. Be sure to read them before
designing.
