Evaluation kit interfaces with MEMS evaluation boards

CML Microcircuits EV6550D Evaluation Kit, available now from Mouser, is designed for the evaluation and application development of the CMX655D. This evaluation kit is designed to interface with MEMS microphone evaluation boards. The evaluation board is in the form of a populated PCB containing the CMX655D IC, supporting components, and circuitry. This board runs from a single 5V power supply supplied by PE0003 or bench power supply when the class-D is disabled. The evaluation board allows the CMX655D to operate at 3.3V or 1.8V via a jumper configuration. When class-D is enabled, an extra power supply connecting directly to the CMX655D is needed, and the power supply should be set to 3.3V.

The board provides two dual-in-line sockets to support evaluation with STEVAL-MIC001V1 or similar boards. This board functions by connecting to the host port on the PE0003 Universal Interface Card. The board can be used with the associated PC GUI software or by direct connection between the CMX655D SPI or TWI. This board can also be used with a μC development application or emulation system.
