Xplain - Atmel Introduces $29 Evaluation Kit for AVR XMEGA
Atmel Corporation today announced the availability of the Xplain evaluation kit for its AVR XMEGATM microcontroller family. With a suggested resale price of $29 USD, this kit enables users the ability to evaluate features and system performance of Atmel's XMEGA at a minimum hardware cost. The kit is powered through a mini USB connector where end-users can develop their own applications on XMEGA using Xplain. The 8-/16-bit XMEGA microcontrollers, introduced in 2008, are optimized for ultra- low power and high system performance with a very innovative and complete feature set well suited for a wide range of applications.
AtmeFor evaluation and development purposes, the Xplain kit contains a speaker with an audio amplifier, a potentiometer and temperature sensor, which are all connected to the 12-bit DAC or ADC on the ATxmega128A1 device. The external memories include an 8 MB SDRAM and an 8 MB serial data Flash, and eight buttons and eight LEDs for basic user interface and application interaction are also available. Spare digital and analog pins on the ATxmega128A1 are available through pin-headers for external analog input and output, digital input and output, PWM, input capture, and USART, SPI and I2C-compatible TWI communication.
The Xplain kit is shipped with basic code programmed into the ATxmega128A1 to demonstrate the use of buttons, LEDs and the speaker on the kit. Documentation includes a user guide, schematics and a full bill of materials available at: http://www.atmel.com/Xplain. Additional code examples, good design practices recommendations and general hints and tips are available as application notes at: http://www.atmel.com/AVR.
Xplain supports other development tools from Atmel including the JTAGICE mkII debugger, AVRISP mkII programmer and AVR Studio® - the free AVR IDE Software Development Tool available at http://www.atmel.com/AVRStudio. By using these tools with Xplain, users have the ability to do on-chip debugging or in-system programming.
