DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD784927, 784928, 784927Y, 784928Y  
16-BIT SINGLE-CHIP MICROCONTROLLER  
DESCRIPTION  
The µPD784927 and 784928 are members of the NEC 78K/IV Series of microcontrollers equipped with a high-  
speed, 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. Be sure to read this  
manual before designing your system.

Serial interface : 3 channels  
3-wire serial I/O : 2 channels  
I2C bus interface: 1 channel  
A/D converter: 12 channels (conversion time: 10 µs)  
Low-frequency oscillation mode: main system clock frequency = internal clock frequency  
Low-power consumption mode: CPU can operate with a subsystem clock.  
Supply voltage range: VDD = +2.7 to 5.5 V  
Hardware watch function: watch operation at low voltage (VDD = 2.7 V (MIN.)) and low current consumption  
Unless otherwise specified, the µPD784927 is treated as the representative model throughout this document.
