SAM4S Series
Atmel | SMART ARM-based Flash MCU
DATASHEET Description
The Atmel В® | SMART SAM4S series is a member of a family of Flash
microcontrollers based on the high-performance 32-bit ARMВ® CortexВ®-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
U S B D e v ic e p o r t w i t h e m b e d d e d t r a n s c e i v e r , a h i g h -s p e e d M C I f o r
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 3channel 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 QTouchВ® 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 …
