SAM3N Flash MCU

Atmel's SAM3N series is ready for capacitive touch thanks to the QTouch library

Image of Atmel's SAM3N Flash MCUAtmel's SAM3N series is a member of a family of Flash microcontrollers based on the high performance 32-bit ARM Cortex-M3 RISC processor. It operates at a maximum speed of 48 MHz and features up to 256 Kbytes of Flash and up to 24 Kbytes of SRAM. The peripheral set includes two USARTs, two UARTs, two TWIs, three SPI, as well as one PWM timer, six general purpose 16-bit timers, an RTC, a 10-bit ADC and a 10-bit DAC. The SAM3N series is ready for capacitive touch thanks to the QTouch library, offering an easy way to implement buttons, wheels and sliders. The SAM3N device is an entry-level general purpose microcontroller. That makes the SAM3N the ideal starting point to move from 8- /16-bit to 32-bit microcontrollers. It operates from 1.62 V to 3.6 V and is available in 48-pin, 64-pin and 100-pin QFP, 48-pin and 64-pin QFN, and 100-pin BGA packages.

Key Features

  • Atmel QTouch Capacitive Touch Support -The SAM3N series is touch-ready, offering native support for Atmel QTouch® technology for easy implementation of buttons, sliders and wheels in applications
  • Data Speedway - Native 3-layer bus AHB matrix support with 10 peripheral DMA channels and distributed memory for high-speed uninterrupted data flows with minimum processor overhead
  • Simplified PCB Design and Low System Cost - Integrated serial resistors eliminate the need for external resistors to preserve signal integrity, resulting in reduced BOM cost, real estate savings and simplified PCB design
  • 1.62 V to 3.6 V operation and low power - 1.62 V to 3.6 V operation and low power true 1.8 V ±10% operation extends device operation when running from two AA alkaline batteries. The SAM3N only consumes 22 mA at 48 MHz operation and 1.9 uA in backup mode with the RTC running
