New SMART SAM E70 flash-based microcontroller from Atmel Corporation. The high-performance Atmel microcontroller is based on a 32-bit ARM Cortex M7 core, which runs at speeds up to 300 MHz with an integrated floating-point unit (FPU). The device enables designers to improve performance and provide SRAM and system functions while retaining the ease of use of the Cortex-M processor family for Internet of Things (IoT) or smart energy gateways, industrial automation and building control applications.
MCUs provide the ideal combination of connectivity, memory and performance. The microcontroller has up to 2048 KB of flash memory and 384 KByes of configurable SRAM, and provides up to 114 programmable input / output pins as well as an ultra-low-power real-time clock (RTC) and 32-bit ultra-low-power clock . Power Real-Time Timer (RTT). A total of twelve general-purpose 16-bit timers are available, and each timer provides stepper motor and quadrature decoder (QDEC) logic support. The SAM E70 allows efficient sampling and generation of external analog signals using a dual 12-bit analog-to-digital converter (ADC) with an analog front end that provides offset and gain error correction, a 12-bit digital-to-analog converter ( DAC)) has differential and oversampling modes, and an analog comparator.
The SAM E70 device has multiple networks and connected peripherals, including a CAN-FD interface and a 10 / 100Mbps Ethernet MAC, and has specific hardware support for Audio Video Bridging (AVB). Other communication interfaces include high-speed USB hosts and devices, high-speed SDCard / SDIO / MMC interfaces, USART, SPI, and multiple two-wire interface (TWI) buses.
Mouser also stocks the Atmel SMART ATSAMV71-XULT Xplained Ultra evaluation kit, a simple hardware platform for rapid evaluation and development of SAM E70 microcontrollers. The kit is based on an ATSAMV71Q21 microcontroller with 2 MBytes QSPI flash. The company says the on-board embedded debugger eliminates the need for any external tools for device programming or debugging.
