UPD784927Y Datasheet 16-bit Single-chip Microcontroller

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET µPD784927, 784928, 784927Y, 784928Y 16-BIT SINGLE-CHIP MICROCONTROLLER MOS INTEGRATED.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The µPD784927 and 784928 are members of the NEC 78K/IV Series of microcontrollers equipped with a highspeed, high-performance 16-bit CPU for VCR software servo control.

The µPD784927Y and 784928Y are based on the µPD784928 with the addition of an I2C bus interface compatible with multi-master.

They contain many peripheral hardware units ideal for VCR control, such as a multi-function timer unit (super timer unit) for software servo control and VCR analog circuits.
