FRDM-CR20A development board
applications. The device is accompanied by a 32 MHz reference oscillator crystal, RF circuitry including
antenna, and supporting circuitry.
The FRDM-CR20A board is intended as the core PCB for MCR20A device evaluation and application
development, and can be used as daughter card to other development boards within the Freescale Freedom
development platform, as an application specific such as a shield card.
