CML Microcircuits EV6550D Evaluation Suite is designed for CMX655D evaluation and application development. The evaluation suite is designed to interface with microelectromechanical Systems (MEMS) microphone evaluation boards. The EV6550D evaluation board comes in the form of a packed PCB, which contains the CMX655D IC, support components and circuits.
This EV6550D board uses a 5V power supply or bench power supply from the PE0003 when Class d is off. The evaluation board allows the CMX655D to operate at 3.3V or 1.8V via a jumper configuration. When class-D is enabled, an additional power supply directly connected to the CMX655D is required and the power supply should be set to 3.3V.
The EV6550D board features two dual in-line sockets that support evaluation with the STEVAL-MIC001V1 or similar board. The board is operated by connecting to the host port of the CML PE0003 universal interface card. The EV6550D board can be used with associated PC GUI software, or directly connected via the CMX655D Serial Peripheral Interface (SPI) or TWI (Two Wire Interface). The board can also be used in μC development applications or simulation systems.
