SAM4E Series
Atmel | SMART ARM-based Flash MCU
DATASHEET Description
The Atmel® | SMART SAM4E series of Flash microcontrollers is based on the
high-performance 32-bit ARM ® Cortex ® -M4 RISC processor and includes a
floating point unit (FPU). It operates at a maximum speed of 120 MHz and
features up to 1024 Kbytes of Flash, 2 Kbytes of cache memory and up to
128 Kbytes of SRAM.
The SAM4E offers a rich set of advanced connectivity peripherals including
10/100 Mbps Ethernet MAC supporting IEEE 1588 and dual CAN. With a singleprecision FPU, advanced analog features, as well as a full set of timing and
control functions, the SAM4E is the ideal solution for industrial automation, home
and building control, machine-to-machine communications, automotive
aftermarket and energy management applications.
The peripheral set includes a full-speed USB device port with embedded
transceiver, a 10/100 Mbps Ethernet MAC supporting IEEE 1588, 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, a parallel I/O capture mode for camera interface, hardware
acceleration for AES256, 2 USARTs, 2 UARTs, 2 TWIs, 3 SPIs, as well as a 4channel PWM, 3 three-channel general-purpose 32-bit timers (with stepper motor
and quadrature decoder logic support), a low-power RTC, a low-power RTT, 256bit General Purpose Backup Registers, 2 Analog Front End interfaces (16-bit
ADC, DAC, MUX and PGA), one 12-bit DAC (2-channel) and an analog
comparator.
The SAM4E devices have three software-selectable low-power modes: Sleep, …
