GENERAL DESCRIPTION

• Power-on-reset and low voltage detector

• Single power supply

The 84C44X; 84C64X; 84C84X denotes the types:

• PCA84C440; 84C441; 84C443; 84C444

• PCA84C640; 84C641; 84C643; 84C644

• PCA84C840; 84C841; 84C843; 84C844.

• 2 power reduction modes: Idle and Stop

• Operating temperature range: −20 to +70 °C

• Silicon gate CMOS fabrication process (SAC2).

which are 8-bit microcontrollers with On Screen Display

(OSD) and Voltage Synthesized Tuning (VST) functions.

All are members of the 84CXXX microcontroller family.

Derivative features PCA84C640

Although the PCA84C640 is specifically referred to

throughout this data sheet, the information applies to all

the devices. The small differences between the 84C640

and the other devices are specified in the text and also

highlighted in Chapter 6.

There are two oscillator types for the OSD function in the

various types, i.e.,

• RC oscillator: PCA84C440; 84C443; 84C640; 84C643;

84C840; 84C843

The PCA84C640 comprises:

• LC oscillator: PCA84C441; 84C444; 84C641; 84C644;

• The PCF84CXXXA processor core

• 6 kbytes mask-programmable program ROM

• 128 bytes RAM

84C841; 84C844.

2.1

Important note

• Multi-master I²C-bus interface

This data sheet details the specific properties of the

PCA84C44X, PCA84C64X and PCA84C84X.

The shared characteristics of the PCA84CXXX family of

microcontrollers are described in the PCF84CXXXA

Family single-chip 8-bit Microcontroller of “Data Handbook

IC14”, which should be read in conjunction with this data

sheet.

• AFC input for Voltage Synthesized Tuning

(VST; with 3-bit DAC and comparator)

• On Screen Display (OSD) facility for two rows of

16-characters

• On Screen Display character set of 64 types
