CAMBRIDGE, UK — Atmel launched the mini USB connector-based Xplain evaluation kit to support its AVR XMEGA microcontroller family.
The kit enables users the ability to evaluate features and system performance of the XMEGA at a minimum hardware cost, powered through a mini USB connector where end-users can develop their own applications.
The 8-/16-bit XMEGA microcontrollers are optimized for ultra- low power and high system. The ATxmega128A1 onboard device 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 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 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.

10 emerging technologies to watch:
EE Times has compiled a list of emerging technologies that we think will be worth watching out for in 2010. Biofeedback or thought-control of electronics are among the contenders.
10 CEOs out in 2009:
It's been a tough year for the global electronics industry and CEOs. We survey the dismissal of 10 industry CEOs during the first three quarters of 2009 and what's ahead for the rest of the year.
Executive pay:
The economy stinks. Rank-and-file engineers are feeling the pain. What about technology CEOs? We crunched the numbers buried in corporate financial statements to find out. Here's what we found.
10 companies in trouble (revisited):
What follows is an updated version of 10 companies in trouble. Some companies have been removed since the last version, others remain. Still others have been added to the mix.
Early predictions for 2010:
The electronics industry is recovering, but there is still some uncertainty in the market. Some see a boom year in 2010. Some see a double dip. So what's in store for the rest of this year and 2010?
Top 10 IC vendors with cash:
The world's biggest IC companies by revenue rank not only among the best in their respective industry segments but are also more likely to have huge piles of cash that can be used to fund acquisitions, R&D and product development.
Notable women in microelectronics:
There is no better time than a global economic recession to examine the keys to successful corporate governance. So, EE Times has compiled an international list that celebrates women who are business and technology leaders in semis.
EE Times updates Silicon 60:
Seventeen companies have been added to the lastest version of our Silicon 60 list of emerging startups. Forty-three companies survived as emerging companies that are still worth watching.
