Under the web page of SAM9N12/CN11-EK, find the test package of AT91SAM9N12/CN11- EK_test_xx_public.zip (xx is the version number), which is the file for Flash content burning. A step-by- step instruction is available in name of SAM9N12/CN11_EK_Test_Software on how to recover the con- tents and how to make test for each section of the boards.
Section 43 Evaluation Kit Hardware Board Overview This section introduces the Atmel SAM9N12/CN11 Evaluation Kit design. It introduces system-level con- cepts, such as power distribution, memory, and interface assignments. ® The SAM9N12/CN11-EK board is built around on the integration of an ARM 926-based microcontroller (BGA 217 package) with on-board SDRAM, NAND-Flash and a set of popular peripherals.
– 2 Gbits NAND Flash memory with chip selection control switch – Optional NOR Flash – 32 Mbits SPI serial DataFlash with chip selection control switch – 512 Kbits serial EEPROM – 1 Kbit 1-Wire EEPROM SAM9N12/CN11-EK User Guide 11186A–ATARM–29-Nov-12...
Two user LEDs and one power LED System buttons: NRST, WKUP, OE_CS One user button 4.2.2 Interface Connection The SAM9N12/CN11-EK board includes hardware interfaces such as: DC power supply (J1) Backup battery (Bt1) USB host, type A connector (J2) USB device, micro B connector (J3)
400 MHz for the core and 133 MHz for the system bus. 4.3.2 Clock Distribution The SAM9N12/CN11-EK board includes three clock systems. Two of the clock systems are alternatives for the SAM9N12/CN11 main clock and one clock system is an oscillator used for the Ethernet controller chip.
The SAM9N12/CN11-EK board evaluation and development platform embeds all the necessary power rails required for the SAM9N12/CN11 processor and peripherals. The SAM9N12/CN11-EK board can be supplied by either a USB connection via J3 or a 5V DC block through input J1 (refer to usb schematic).
3 (Outside) Ground 4.3.5 Power Rails The SAM9N12/CN11-EK Board contains three regulated power supplies: 3.3V DC supply 1.8V DC supply 1.0V DC core supply The outputs of these regulated power supplies are distributed as necessary to the circuits on boards.
TP13 and jumper JP2 are used to perform testing. Figure 4-9. Backup Battery +3V3 VDDBU BAT54C J P2 TP13 100nF 2.2uF Note: Test points (TPn) are provided for easy access to each of the regulated power lines. SAM9N12/CN11-EK User Guide 11186A–ATARM–29-Nov-12...
D[0-15]. 4.3.7.2 NAND FLASH The SAM9N12/CN11-EK has native support for NAND Flash memory and implements an 8-bit NAND Flash with 2 Gbits in size. One 2 Gbits NAND Flash (Micro MT29F2G08ABDHC), 16 bits data interface connected to D[0-15].
4.3.9 JTAG Interface The SAM9N12/CN11-EK board includes a JTAG interface port (J4), to provide debug level access to the processor. The JTAG port is a 20-pin male connector. This port provides the required interface for in-cir- cuit emulators such as ARM’s Multi-ICE.
Host full speed, type A USB receptacle, J2 Device full speed, micro B USB receptacle, J3 SAM9N12/CN11-EK features USB power function from device port J3. SW1 functions as switch between USB supply and DC input jack J1. The USB host ports are equipped with 500 mA power switch for bus-powered applications.

The bit clock is shared; it can be the SSC Transmitter Clock (TK) or the Receiver Clock (RK). The default setting on SAM9N12/CN11-EK is TK and RK shorted together through R159/R160. Please note that try- ing different ADC/DAC rates would mean different RK/TK rates; this default setting can be modified.
4.3.17 ZigBee Interface The EK board has a 10-pin male connector for the Atmel RZ600 ZigBee module. DNP 0-ohm resistors have been implemented in series with the PIO lines that are used elsewhere in the design. Thereby, it enables their individual disconnection, should a conflict occur in user application.
4.3.19 LED Indicators There are three LEDs for general purpose on the SAM9N12/CN11-EK board: D8 blue and D9 green LEDs are user defined and controlled by the GPIO. D10 red LED is a power LED indicating that the 3.3V rail is enabled. It can also be controlled by the GPIO (by default, the GPIO is disabled and an on-board pull-up to 3.3V lights the LED).
4.3.20 Push Buttons SAM9N12/CN11-EK has three mechanical push buttons for system application (PB1 to PB3) and one for free use (PB4). 4.3.20.1 PB1 Output Enable Chip Select Access to the RomBoot: 1. Press simultaneously the PBs OE-CS and NRST 2. Release the PB NRST 3.
