Consumer Microcircuits Limited CMX8341
the CMX8341, managing voice and data systems autonomously including the Vocoder minimises host microcontroller interactions enabling the lowest operating power and therefore the longest battery life for a dPMR radio. The CMX8341 utilises CML’s proprietary FirmASIC component technology. The Function Image™ can be loaded automatically from an external serial memory or host µController over the built-in C-BUS serial interface.| Part No. | CMX8341 |
