6495B–ATARM–21-Apr-10

The SAM9M10 provides two high-speed Serial Peripheral Interface (SPI) controllers. One port is used to 
interface with the on-board serial DataFlash

®

.

Figure 4-15.  SPI

The SAM9M10 has a full speed (400 kHz) master/slave I2C Serial Controller. The controller is fully com-
patible with the industry standard I2C and SMBus Interfaces. This port is used to interface with the on-
board Serial EEPROM, ISI and TV encoder interface.

The SAM9M10-G45-EK has two high-speed 8-bit multimedia interfaces MMC/MMCPlus v4.1. The first 
interface is used as an 8-bit interface (MCI1), connected to a CE-ATA connector footprint and an 8-bit 
SD/MMC card slot. The second interface is used as a 4-bit interface (MCI0), connected to a 4-bit 
SD/MMC card slot. 

The users must provide their own compatible cards for use with these connectors.

Please note that the power is connected to VCC, which is 3.3 volts.
