DATA SHEET µPD784927, 784928, 784927Y, 784928Y 16-BIT SINGLE-CHIP MICROCONTROLLER MOS INTEGRATED CIRCUIT 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. Flash memory models, the µPD78F4928 and µPD78F4928Y, are under development. The functions of the µPD784927 is described in detail in the following User’s Manual.
