Electronica, Munich – The SAM3N series is an expansion of the Atmel ARM Cortex-M3 flash family and is a general-purpose microcontroller targeted at applications including consumer, industrial control, metering, toys, medical, test and measurement, 802.15.4 wireless networking, and PC, cell phone and gaming peripherals.
The Atmel SAM3N and SAM3S series provide capacitive touch support for buttons, sliders and wheels with the Atmel QTouch library and studio to deploy modern-user interfaces.
The series has an extended supply range from 1.62 to 3.6V to enable a true 1.8V operation and 0.86mW per megahertz in active mode. The lower power consumption can also be reduced to 1.9uA in 1.8V standby mode with RTC (real-time clock) running.
The Atmel SAM3N Cortex-M3 flash series is pin-to-pin compatible with the Atmel ARM7TDMI-based SAM7S series to provide a migration path to higher performance and lower power consumption.
The SAM3S provides peripheral options which include 12-bit ADC, SDIO, USB full-speed device, external bus interface, and more flash SRAM options.
The Atmel SAM3N series has 64k to 256 kbyte flash memory options, connectivity capabilities and user interface support. Its peripherals including ADC/DAC and up to 16 timers and four UARTs supporting ISO7816 standard. In addition, functionality like on-die-termination (ODT) for simplification of PCB design has been integrated.
The Atmel SAM3N series is ramping production now in 64k, 128k, 256k bytes flash memory densities. The devices are available in the following packages and sizes: 48-, 64- and 100-pin 0.5mm pitch QFP, in 100-ball 0.8mm pitch BGA, and 48- and 64-pin 0.45mm pitch QFN packages.
A development board is avaulable as are ready-to-use projects for the GNU GCC, IAR EWARM and Keil µVision compilers.
