Atmel's Cortex-M3-based Flash MCUs Improve Impedance Matching, Lower Power Up to 50%

(Product News, 17 Dec 2009)

Atmel Corp.'s SAM3S series of general-purpose Cortex-M3 based Flash microcontrollers improve impedance matching, simplify PCB design and save 50 percent power at 1MHz operation with a consumption of only 2.3mW. At maximum operating frequency of 64MHz the device consumes 1.45mW/MHz. These MCUs enable ARM7TDMI-based SAM7S customers to migrate to a 50 percent more powerful and feature-rich MCU, while preserving hardware and software investments. Atmel's SAM3S also expands market opportunities in applications including consumer, industrial control, metering, toys, medical, test and measurement, 802.15.4 wireless networking, PC, cell phone and gaming peripherals.

The SAM3S is a member of Atmel's Flash microcontroller family based on the high-performance 32-bit ARM Cortex-M3 RISC processor. It provides processing power and features such as system control, sensor interfaces, 64kB to 256kB Flash memory options, an optional external parallel bus interface, connectivity capabilities and user interface support. Additional features include On-Die Termination (ODT), USB Device, SDIO, Parallel PIO signal capture, 12-bit ADC and DAC, fours UARTs, dual I2C, I2S, timers, unique chip ID, and power and reset management. The SAM3S's supply voltage ranges from 1.62 to 3.6V operation and package options from 48-pin QFP and QFN up to 100-pin QFP and BGA.
