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.
FEATURES
PCF84CXXXA kernel
• 8-bit CPU, ROM, RAM, I/O in a single 42 leads shrink DIL package
• Over 80 instructions all of 1 or 2 cycles
• 29 quasi-bidirectional standard I/O port lines
• Configuration of I/O lines individually selected by mask
• External interrupt INT/T0
• 2 direct testable inputs T0 and T1
• 8-bit programmable timer/event counter
• 3 single level vectored interrupts (external, timer/counter, I2C-bus)
• Power-on-reset and low voltage detector
• Single power supply
• 2 power reduction modes: Idle and Stop
• Operating temperature range: −20 to +70 °C
• Silicon gate CMOS fabrication process (SAC2).
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.
