ATSAM4E-XPRO

The Microchip | SMART SAM4E series of Flash microcontrollers is based on thehigh-performance 32-bit ARM Cortex -M4 RISC processor and includes afloating point unit (FPU). It operates at a maximum speed of 120 MHz andfeatures up to 1024 Kbytes of Flash, 2 Kbytes of cache memory and up to128 Kbytes of SRAM.The SAM4E offers a rich set of advanced connectivity peripherals including10/100 Mbps Ethernet MAC supporting IEEE 1588 and dual CAN. With a singleprecisionFPU, advanced analog features, as well as a full set of timing andcontrol functions, the SAM4E is the ideal solution for industrial automation, homeand building control, machine-to-machine communications, automotiveaftermarket and energy management applications.The peripheral set includes a full-speed USB device port with embeddedtransceiver, a 10/100 Mbps Ethernet MAC supporting IEEE 1588, a high-speedMCI for SDIO/SD/MMC, an external bus interface featuring a static memorycontroller providing connection to SRAM, PSRAM, NOR Flash, LCD Module andNAND Flash, a parallel I/O capture mode for camera interface, hardwareacceleration for AES256, 2 USARTs, 2 UARTs, 2 TWIs, 3 SPIs, as well as a 4-channel PWM, 3 three-channel general-purpose 32-bit timers (with stepper motorand quadrature decoder logic support), a low-power RTC, a low-power RTT, 256-bit General Purpose Backup Registers, 2 Analog Front End interfaces (16-bitADC, DAC, MUX and PGA), one 12-bit DAC (2-channel) and an analogcomparator.The SAM4E devices have three software-selectable low-power modes: Sleep,Wait and Backup. In Sleep mode, the processor is stopped while all otherfunctions can be kept running. In Wait mode, all clocks and functions are stoppedbut some peripherals can be configured to wake up the system based onpredefined conditions.The Real-time Event Managment allows peripherals to receive, react to and sendevents in Active and Sleep modes without processor intervention.
