ATSAM3S4AA-AU IC MCU 32BIT 256KB FLASH 48LQFP

Description

Atmel's SAM3S 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 64 MHz and features up to 256 Kbytes of Flash and up to 48 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 providing connection to SRAM, PSRAM, NOR Flash, LCD Module and NAND Flash, 2x USARTs, 2x UARTs, 2x TWIs, 3x SPI, an I2S, as well as 1 PWM timer, 6x general-purpose 16-bit timers, an RTC, an ADC, a 12-bit DAC and an analog comparator. The SAM3S series is ready for capacitive touch thanks to the QTouch library, offering an easy way to implement buttons, wheels and sliders The SAM3S device is a medium range general purpose microcontroller with the best ratio in terms of reduced power consumption, processing power and peripheral set. This enables the SAM3S to sustain a wide range of applications including consumer, industrial control, and PC peripherals. It operates from 1.62V to 3.6V and is available in 48-, 64- and 100-pin QFP, 48- and 64-pin QFN, and 100-pin BGA packages. The SAM3S series is the ideal migration path from the SAM7S series for applications that require more performance. The SAM3S series is pin-to-pin compatible with the SAM7Sseries.
