AT91SAM9M10-G45-EK User Guide
Serial Peripheral Interface Controller (SPI)
Two Wire Interface (TWI)
SD/MMC Interface
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.
Figure 4-16. TWI
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.
