SAM3X/A
SAM3X/A
Atmel’s SAM3X/A 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
84 MHz and features up to 512 Kbytes of Flash and up to 100 Kbytes of SRAM. The peripheral
set includes a High Speed USB Host and Device port with embedded transceiver, an Ethernet
MAC, 2x CANs, a High Speed MCI for SDIO/SD/MMC, an External Bus Interface with NAND
Flash controller, 5x UARTs, 2x TWIs, 4x SPIs, as well as 1 PWM timer, 9x general-purpose 32-
bit timers, an RTC, a 12-bit ADC and a 12-bit DAC.
The SAM3X/A series is ready for capacitive touch thanks to the QTouch library, offering an easy
way to implement buttons, wheels and sliders.
The SAM3X/A architecture is specifically designed to sustain high speed data transfers. It
includes a multi-layer bus matrix as well as multiple SRAM banks, PDC and DMA channels that
enable it to run tasks in parallel and maximize data throughput.
It operates from 1.62V to 3.6V and is available in 100- and 144-pin QFP and LFBGA packages.
The SAM3X/A devices are particularly well suited for networking applications: industrial and
home/building automation, gateways.
