Description
The Atmel® | 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 Atmel QTouch® library for easy implementation of buttons, wheels and sliders.
The Atmel | SMART SAM4S devices have three software-selectable low-power modes: Sleep, Wait and Backup. In Sleep mode, the processor is stopped while all other functions can be kept running. In Wait mode, all clocks and functions are stopped but some peripherals can be configured to wake up the system based on predefined conditions. In Backup mode, only the low-power RTC and wakeup logic are running. The real-time event management allows peripherals to receive, react to and send events in Active and Sleep modes without processor intervention. The SAM4S 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 SAM4S to sustain a wide range of applications that includes consumer, industrial control, and PC peripherals. SAM4S devices operate from 1.62V to 3.6V. The SAM4S series is pin-to-pin compatible with the SAM3N, SAM3S series (48-, 64- and 100-pin versions), SAM4N and SAM7S legacy series (64-pin versions).
