Product description

The CMX7045 is a dedicated processor for marine Automatic Identification System (AIS), Search and Rescue Transmitter (SART) operation, fully meeting the requirements of IEC 61097-14.

This highly integrated and flexible device includes a 9600 baud GMSK modem for the transmission of formatted data.
Additional auxiliary functions are provided to support the system host, these include: a two-input 10-bit ADC, four 10-bit DACs, two system clock outputs and four GPIOs.

To ensure maximum system battery life, the CMX7045 offers low power sleep modes, and is available in a in small 48-pin LQFP or VQFN packages.
