    AT91RM9200-CJ-002 Typical application Circuitry


    The AT91RM9200-CJ-002 is a high-performance, low-power Microcontroller Unit (MCU) based on the ARM920T processor developed by Microchip (formerly Atmel). This microcontroller includes a wide range of peripherals, including a USB 2.0 full-speed device and host, Ethernet MAC 10/100 base-T, and a number of standard interfaces like UART, SPI, and I2C. Here is a high-level description of a potential application circuit for the AT91RM9200-CJ-002: 

    1. Power Supply: The AT91RM9200-CJ-002 operates at a core voltage of 1.8V and I/O voltage of 3.3V. A power source that can give these voltages consistently is required. Bypass capacitors should be installed near the power supply pins (VDDCORE, VDDIOP0, VDDIOP3) to smooth out any voltage spikes or dips. 
    2. Oscillator Circuit: Both an external crystal or ceramic resonator and an internal RC oscillator are supported by this microcontroller. You can connect the resonator to the XIN and XOUT pins, with load capacitors to ground to stabilize the frequency. 
    3. Reset Circuit: Connect a power-on reset circuit to the NRST pin. This usually consists of a simple RC network and ensures that the microcontroller starts in a known state when power is applied. 
    4. Memory: The AT91RM9200-CJ-002 microcontroller has a Static Memory Controller (SMC) that can interface with a variety of memory types, such as SRAM, Flash, and SDRAM. Connect these memory modules to the appropriate data and address buses. 
    5. Peripherals: The MCU provides a plethora of peripherals. Connect the Ethernet, USB, UART, SPI, and I2C ports to the respective devices or modules, following the guidelines in the datasheet. 
    6. Debugging Interface: For in-system programming and debugging, you can use the JTAG interface. Connect the TDI, TDO, TMS, TCK, and NRST pins to your JTAG debugger. 
    Remember that this is a simplified application circuit description. Depending on your specific design requirements, you'll need to consider other factors such as noise, power management, and the specific needs of your peripherals. Always refer to the AT91RM9200-CJ-002 datasheet and other technical documentation provided by Microchip for accurate and complete information.
