Brief Description The CMX7031/CMX7041 FI 1.5 is a full-function, half-duplex, audio, signalling and data processor IC. This makes it a suitable device for both the leisure radio markets (FRS, MURS, PMR446 and GMRS) and for professional radio products (PMR/LMR, Marine and Trunking) with or without signalling and data facilities. The device utilises CML’s proprietary FirmASIC component technology. On-chip sub-systems are configured by a Function Image ™: this is a data file that is uploaded during device initialisation and defines the device’s function and feature set. The Function Image™ can be loaded automatically from an external EEPROM or from a host µController over the built-in C- BUS serial interface. The device’s functions and features can be enhanced by subsequent Function Image ™ releases, facilitating in-the-field upgrades. This document refers specifically to the features provided by Function Image ™ 1.5. Continued… |
