28 June 2012 Atmel claims highest flash density for Cortex-M4 based mcu Atmel is sampling the SAM4SD32, said to be the first Cortex-M4 based microcontroller (MCU) to feature 2Mbyte of flash. The device is said to consume 200µA/MHz in active mod at 120MHz, more than 50% less than its nearest competitor. "We are continuing to expand our ARM portfolio of devices for higher performance applications and growing memory requirements in the consumer and industrial segments," said Ingar Fredriksen, Atmel's senior director of microcontrollers. "These new products with the latest Cortex-M4 core will ensure designers have all the right devices they need for their design requirements." According to Atmel, the part also features 160kbyte of sram and integrates code protection features. Meanwhile, the embedded flash is dual banked to support in field firmware upgrades. SAM4SD32 code development is supported by the SAM4S-EK2 evaluation kit which, in turn, is supported by the Atmel Studio 6 integrated development environment. The SAM4SD32 will be available in a VFBGA100 7x7mm package.
