San Jose, Calif.—Atmel's battery development kit, the ATAVRSB100, speeds time to market for lithium-ion designs using the company's ATmega406 'smart battery' chip.
"The ATAVRSB100 implementation allows any engineer regardless of prior knowledge of smart batteries to get a jump-start in their development," said Odd Jostein Svendsli, marketing manager for battery management solutions. "At the same time, engineers can focus on implementing accurate algorithms for their specific battery, knowing that all basic functions are already covered."
The ATAVRSB100 development board comprises three different support modules to simulate individual cell voltage, total cell stack voltage, and charge/discharge current. These modules allow developers to simulate critical battery situations for their laptop, medical equipment and portable instrumentation applications. Several connectors are available to facilitate easy connection to battery cells and quick debugging.
The firmware supplied with the ATAVRSB100 defines the framework to develop customized firmware. It supports full SMBus V1.1 protocols, as well as basic algorithms to estimate the remaining charge and allow battery designers to focus on firmware development for the advanced "state of charge" and "state of health" algorithms unique to each battery type. Support for firmware updates through SMBus is also available. To simplify the calibration procedure, the firmware supports calibration through the SMBus interface.

The ATmega406, designed as the first complete Flash-based microcontroller solution to meet the accuracy and reliability challenges for smart batteries at the lowest system cost, is priced starting at $3.10 each in 10k quantities.
