1.2 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.
The PCA84C640 comprises:
The PCF84CXXXA processor core
6 kbytes mask-programmable program ROM
128 bytes RAM
Multi-master I2C-bus interface
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
Four programmable display dot sizes
Half dot character rounding
Seven colours for each character
One 14-bit PWM output for VST
Five 6-bit PWM outputs for analog controls
Eight port lines with 10 mA LED drive capability
18 general purpose bidirectional I/O lines
plus 11 function-combined I/O lines
2 direct testable lines
Programmable VSYNCN and HSYNCN input polarity
RC oscillator for OSD function.
2 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.
2.1 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.
