Atmel announced the availability of the Xplain evaluation kit for its AVR XMEGA microcontroller family, allowing designers to evaluate features and system performance of Atmel’s XMEGA at a minimum hardware cost.
The onboard device in the kit – the ATxmega128A1 – is a 100-pin general-purpose microcontroller with 128 KB of in-system programmable Flash memory and an 8 KB boot section in Flash that can also be used as additional application memory.
The MCU contains all features available in the XMEGA family which include, but are not limited to, a DMA controller, event system, 12-bit high-speed analog peripherals, AES and DES crypto module, external bus interface and all second-generation picoPower features.
For evaluation and development purposes, the Xplain kit is powered through a mini USB connector and 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 DataFlash, and eight buttons and eight LEDs are provided for basic user interface and application interaction. 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.
