ATSAM4N-XSTK

The SMART SAM4S series is a member of a family of Flash microcontrollers based on the high-performance 32-bit ARM Cortex-M4 RISC processor. It operates at a maximum speed of 120 MHz and features up to 2048 Kbytes of Flash, with optional dual-bank implementation and cache memory, and up to 160 Kbytes of SRAM. The peripheral set includes a full-speed USB Device port with embedded transceiver, a high-speed MCI for SDIO/SD/MMC, an External Bus Interface featuring a Static Memory Controller to connect to SRAM, PSRAM, NOR Flash, LCD Module and NAND Flash, 2 USARTs, 2 UARTs, 2 TWIs, 3 SPIs, an I2S, as well as a PWM timer, two 3-channel general-purpose 16-bit timers (with stepper motor and quadrature decoder logic support), an RTC, a 12-bit ADC, a 12-bit DAC and an analog comparator.

The SAM4S series is ready for capacitive touch, offering native support for the QTouch library for easy implementation of buttons, wheels and sliders.
