ATSAM4S2BA-AU

ARM MCU, SAM4S Series, SAM32 Family SAM 4S Series Microcontrollers, ARM Cortex-M4, 32bit, 120 MHz

The ATSAM4S2BA-AU is a SMART SAM4S series 32-bit Flash Microcontroller based on the high-performance ARM Cortex-M4 RISC Processor. It operates at a maximum speed of 120MHz and features 128kB of flash memory and 64kB 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 16bit timers (with stepper motor and quadrature decoder logic support), an RTC, a 12-bit ADC, a 12-bit DAC, and an analog comparator. The device operates from 1.62V to 3.6V. It is ready for capacitive touch, offering native support for the Atmel QTouch® library for easy implementation of buttons, wheels, and sliders. The real-time event management allows peripherals to receive, react to and send events in active and sleep modes.
