Conn ectCor e™ for i.MX 28™ Ha rdwa re Re fe rence I2C The ConnectCard for i.MX28 contains 2 two-wire SMB/I2C bus interfaces. Each interface can act as a slave or a master on the SMB. The I2C interfaces are multiplexed with the DUART, and I2C0 is used for the DUART on the development board, and no termination resistors are on the module for this interface. I2C1 is used to run the 1-wire interface, and 2.2K ohm termination resistors are located on the module. The supply voltage of these resistors is 3.3V.
Conn ectCor e™ for i.MX 28™ Ha rdwa re Re fe rence persistent bits use persistent storage and reside in a special power domain (crystal domain) that remains powered up even when the rest of the chip is in its powered-down state. The ConnectCard for i.MX28 development board does not include a backup battery, so the RTC will not be maintained through power cycles. Liquid Crystal Display (LCD) Some versions of the ConnectCard for i.MX28 includes an LCD connector that is separate from the edge connector.
Conn ectCor e for i.M X53 NAND FLASH The ConnectCard for i.MX28 module includes either 128MB or 256MB of NAND FLASH from the Micron Technologies MT29F series. These chips operate from 1.8V.
