ATSAM3U ARM-CM3开发板硬件指标:

The connectors on the AT91SAM3U evaluation board provide easy access to many of the AT91SAM3U’s on-chip peripherals.

Serial Port

A standard DB9 connector is on the AT91SAM3U board for the AT91SAM3U’s built-in UART interfaces. This is a full duplex, serial port.

CAN Port

A standard DB9 connector for applications requiring CAN communications.

USB Port

A standard USB Type B connector for applications requiring USB communications.

LCD Display

A detachable, 240x320 TFT, color LCD display. You may use this graphic display device to show real-time debug and program status messages.

On-board Battery

A removable, lithium battery is included on the AT91SAM3U to maintain power to the real-time clock when the board disconnects from the main power supply.

Analog Voltage Control for ADC Input

An adjustable analog voltage source for testing the Analog to Digital converter built into the AT91SAM3U.

External Memory

The AT91SAM3U board includes 1 Mbyte of external static RAM and 8 Mbytes of external SPI Flash memory.

MicroSD Card Connector

A MicroSD Card connector for developing applications requiring access to MicroSD Cards.

ETM Trace Debug

An ETM connector for on-chip debugging via the Embedded Trace Macrocell capabilities of the STM32F103 device.

JTAG Download and Debug

A JTAG on-chip debug interface, coupled with the ULINK USB-JTAG adapter, provides flash programming and real-time in-circuit emulation of the ATSAM3U device.
