Packet IC modem CMX7143

for communicationdatawireless

The CMX7143 is a unique, highly-flexible single IC product offering wide-ranging wireless data operations in one hardware package. Built on CML’s proprietary FirmASIC technology, this IC can be configured by a Function Image (FI) file to one of three individual functions: GMSK/GFSK Packet Data Modem 4FSK Packet Data Modem FFSK/MSK Modem Operation, in the host equipment, to alternative data schemes is achieved literally at the ‘press of a button’. FirmASIC IC function and configuration is achieved by the loading of a compact Function Image file at start-up or when a change of data scheme is required. Function Image files, which are downloadable from the CML website, can be easily ‘swopped’ in the field by the host µC to allow the system to operate to an entirely different (data) scheme. The Function Image can be loaded automatically from an external EEPROM or from a host µController over the built-in C-BUS serial command/data interface.
