Evaluation Kit Atmel AT91SAM9G20-EK

Detailed Description

This guide focuses on the AT91SAM9G20-EK board as an evaluation platform. The board supports the AT91SAM9G20 in a 217-ball LFBGA RoHS-compliant Package.

The AT91SAM9G20-EK requires 5V DC (±5%). DC power is supplied to the board via the 2.1 mm by 5.5 mm socket J1. Coaxial plug center positive standard.

The board is equipped with an AT91SAM9G20 microcontroller together with the following:

• 64 Mbytes of SDRAM memory
• 256 Mbytes of NAND Flash memory
• one Atmel serial DataFlash
• one Atmel TWI serial EEPROM
• one USB Device port interface
• two USB Host port interfaces
• one DBGU serial communication port
• one complete MODEM serial communication port
• one additional serial communication port with RTS/CTS handshake control
• JTAG/ICE debug interface
• one PHY Ethernet 100-base TX with three status LEDs
• one on-board Audio DAC
• one Power LED and one general-purpose LED
• two user-input push buttons
• one Wakeup-input push button
• one reset push button
• two DataFlash SD/MMC card slots
• four expansion connectors (PIOA, PIOB, PIOC, IMAGE SENSOR)
• one BGA-like EBI expansion footprint connector
• one Lithium Coin Cell Battery Retainer for 12 mm cell size

Deliverables

• an AT91SAM9G20-EK board
