Roll over image to zoom in

The NXP® SD Card Reader (DEMOFLEXISJMSD) reference design allows you to read and write files stored in a SD Card from a PC or another USB host-enabled system through the full speed USB module included. The SD Card interface is based on SPI protocol. Mass Storage Device class is used to implement the high level communication between the host application and data memory.

This design is an alternative Flexis® JM family development board and you can exchange a MCF51JM128 for a MC9S08JM60 (pin-to-pin compatible). It includes two user LED’s, one button and one expansion header that allows users to access other MCU peripherals like SPI, RGPIO, etc.
