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).
