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
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 3 ORDERING INFORMATION
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.
