Atmel is offering an evaluation kit for its AVR XMEGA
microcontroller family priced at $29.
Called the Xplain kit, it 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 8Mbyte SDRAM and an 8Mbyte serial
data flash, and eight buttons and eight LEDs for basic user
interface and application interaction are also available.
Spare digital and analogue 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.
Atmel's ATxmega128A1 is the
onboard XMEGA device in the Xplain kit. The device is a 100-pin,
general purpose microcontroller with 128kbyte of in-system
programmable flash memory and an 8kbyte boot section in flash that
can also be used as additional application memory.
The ATxmega128A1 contains all features available in the XMEGA
family which includes, but is 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 achieving the market's lowest power consumption
microcontrollers.
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 .
