Cortex-M4 Based MCU Offers 2 MB Of Embedded Flash

Atmel is sampling the SAM4SD32, proclaiming it as the industry’s first Cortex-M4 processor-based MCU with 2MB of embedded Flash. The unit boasts a low power consumption of 200 µA/MHz in active mode, and with 2 MB of embedded Flash, it is well suited for industrial and consumer applications requiring increased program memory, data storage and low power consumption. Such applications include wireless thermostats, GPS sport watches, smart meters and 1D bar code readers. The MCU runs at a 120 MHz operating frequency and features cache memory for accelerated code execution out of Flash. In addition, the device integrates code protection features, 160KB of SRAM, and dual-bank Flash for safe in-field firmware upgrades. The SAM4SD32 is sampling now with general availability slated for September 2012 in QFP100 packaging priced at $7.94 each/1000. It will also be available in a smaller VFBGA100 7 x 7 mm package. Also sampling now, the SAM4S-EK2 full-featured kit supports the SAM4SD32 for faster development and code execution, and will be priced at $149.
