µPD784915A, 784916A

16-BIT SINGLE-CHIP MICROCONTROLLERS

DESCRIPTION

The µPD784915A, 784916A are members of the NEC 78K/IV Series of microcontrollers equipped with a high-

speed 16-bit CPU and are the successors of the 78K/I Series 8-bit single-chip microcontrollers for VCR software

servo control.

This series contains many peripheral hardware units ideal for VCR control, such as a multi-function timer unit

(super timer unit) suitable for software servo control and VCR analog circuits.

A one-time PROM version of the µPD784916A, the µPD78P4916, is also available.

The functions of the µPD784916A are described in detail in the following user’s manuals. Be sure to read

them before designing.
