PCA84C923 General Description
The PCA84C922A, PCA84C922C, PCA84C923A, PCA84C923C and PCA84C923D are members of the PCF84CXXXA CMOS family of microcontrollers and have been designed for use in universal infrared remote commander applications. The term PCA84C92X is used throughout this data sheet to refer to all devices in the range, differences between devices are shown in Table 1 and also highlighted in the text. In addition to the common functions of the PCF84CXXXA family of microcontrollers the PCA84C92X also provides:
· a Hardware Modulator that generates programmable pulse trains for driving an infrared LED
· an on-chip Coding Table specifically for the storage of code data
· a modified interrupt architecture that will wake-up the CPU from the Idle or Stop modes when any key is pressed
· a Watchdog Timer to prevent CPU lock-up.
The PCA84C923D has been designed as the emulation chip for both the PCA84C92X and the PCA84CX22 range of microcontrollers (both ranges being pin compatible).
