GENERAL DESCRIPTION
The 84C44X; 84C64X; 84C84X denotes the types:
PCA84C440; 84C441; 84C443; 84C444
PCA84C640; 84C641; 84C643; 84C644
PCA84C840; 84C841; 84C843; 84C844,
which are 8-bit microcontrollers with On Screen Display
(OSD) and Voltage Synthesized Tuning (VST) functions.
All are members of the 84CXXX microcontroller family.
There are two oscillator types for the OSD function in the
various types, i.e.,
RC oscillator: PCA84C440; 84C443; 84C640; 84C643;
84C840; 84C843
LC oscillator: PCA84C441; 84C444; 84C641; 84C644;
84C841; 84C844.

Important note
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.
