AT91SAM7X-EK development board using the ATMEL AT91SAM7X256 microprocessor core, which can start as a beginner's tool for ARM, but also as a tool for business users AT91SAM7X256 assessment, the biggest highlight of the development board are: industrial The CPU, 1 Road, CAN-Bus interface, 1 channel 10/100M network, a USB Device (2.0) interface, an SD card socket (rear panel), all I / O, lead.
AT91SAM7X256 microcontrollers with embedded 10/100 Ethernet (Ethernet) MAC, CAN, full-speed (12Mbps) USB 2.0. Designed for extensively networked, real-time embedded systems, the AT91SAM7X256 also have a 10-bit ADC (ADC), two serial peripheral interface (SPI), synchronous serial interface (SSC), two-wire interface (TWI) Three Universal Asynchronous Receiver Transmitter (UART), a 8 (8-level) priority interrupt controller (priority interrupt controller) and numerous regulatory functions. The new 50 MIPS MCU with 64KB SRAM and 256KB of 25ns flash memory to support real-time control system that required for deterministic processing.
CPU: AT91SAM7X256 (ATMEL Corporation produced), ARM7, 100Pins-LQFP package, industrial chip; with CAN controller, network controller, USB 2.0 Device, SPI (two), TWI, USART, TC, ADC and other resources.
* 1 channel CAN interface: The biggest feature board, compatible CAN2.0A / B protocol
* 1 100 Network Interface: Single port Fast Ethernet 10M/100Mbps
* 1 USB 2.0 Device port: with hardware detection circuit, enabling communication with a PC
* 2 serial ports:
* I / O expansion: expansion of all the I / O signal lines for the secondary development and expansion
* IIC circuits: external ATMEL's EEPROM (AT24C08)
* Button / LED: 4 user-defined touch of a button and LED, to be completed "Marquee" and other basic experiments, while the development process, users can define their own functions
* JTAG: 20Pins standard JTAG socket.
* Power: USB powered
* SD card socket
Platform: IAR, ADS, KEIL
