The 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 single precision 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 4- channel 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, 256- bit 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, 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. The Real-time Event Management allows peripherals to receive, react to and send events in Active and Sleep modes without processor intervention.
