    AT91SAM9X25-CU Typical application Circuitry


    The AT91SAM9X25-CU is a high-performance microcontroller manufactured by Microchip. It is built around an ARM926EJ-S core and is known for its robust feature set and advanced connectivity options. Here, we will explore how to establish an in-depth circuit connection with the AT91SAM9X25-CU, focusing on the key pins and functionalities of the microcontroller.

    1. Power Pins (SCORE, RADIO, VDD PLL, GND): The AT91SAM9X25-CU has several power and ground pins. SCORE is the power supply for the core and needs to be connected to the appropriate voltage level. Similarly, RADIO is for the I/O power supply, and VDDPLL is for the PLL power supply. The common ground of the system must be connected to each and every GND pin.

    2. DDR2 Memory Interface:The AT91SAM9X25-CU is capable of interfacing with DDR2 type memory. Pins such as DDR_D[0:15], DDR_ADD[0:13], DDR_BA[0:2], and DDR_CS are used for this purpose. The exact connection to these pins will be determined by your specific DDR2 module.

    3. Ethernet Ports (RMI): The microcontroller includes two Fast Ethernet Macs. The Mix_RED[0:1], Mix_TED[0:1], Mix_REF_ELK, and Mix_CRS_DV pins are used for data reception, transmission, reference clock, and carrier sense/data valid signals respectively.

    4. USB Ports:USB data transmission uses the USB_DP and USB_DM pins. Observe the insertion and removal of USB devices by using USB_BUS.

    5. SPI Interface:The AT91SAM9X25-CU features a Serial Peripheral Interface (SPI). The MISS, MOST, SICK, and NPCS[0:3] pins are used for this interface.

    6. Reset (NRST):The reset pin is identified by the NRST pin. It is an active-low signal; hence, it is typically tied to the power supply via a resistor.

    7. Boot Mode (BS1, BS2):The boot mode pins BS1 and BS2 are used to configure the boot mode of the AT91SAM9X25-CU. They can be tied to RADIO or GND to select the desired mode.

    It's crucial to remember that the AT91SAM9X25-CU is a sophisticated microcontroller with many pins. Always consult the device data sheet for the accurate pinout and additional details.

    Also, ensure that adequate decoupling capacitors are installed close to the power pins to maintain the power supply's stability and reduce noise.
