Atmel Introduces ARM Cortex M0+ based SmartConnect Wi-Fi Modules and SmartConnect Zigbee SoCs

In order for the Internet of Things to take off, wireless connectivity solutions with ultra low power, lost cost, and small footprint are needed. Atmel seems to have made a step in the right direction by launching SmartConnect Wi-Fi modules and Zigbee SoCs featuring an ARM Cortex M0+ core. SmartConnect Wi-Fi does not appear to be a single chip solution, but instead Atmel has created a family of Wi-Fi modules integrating the company’s ultra-low power Wi-Fi SoChip with an ARM Cortex M0+ based MCU. These modules will enabled battery-powered Wi-Fi connectivity for IoT endpoints such as thermostats, and temperature sensors in a cost effective way. The company will provide a software solution with application and security protocols such as TLS, TCP/IP stack and an RTOS, all of which can be downloaded via Atmel Studio 6 Integrated Development Platform (IDP). SmartConnect ZigBee SAM R21 combines an ARM Cortex M0+ core with […]

ARM Unveils Cortex-M Prototyping System Based on Altera Cyclone V FPGA

Before micro-controllers or processors are manufactured, simulation is performed in (usually) expensive boards based on FPGA chips from Altera or Xilinx, and once designers have found the system to work as expected, they can move to the next phase and work on the actual silicon. ARM has just released V2M-MPS2 Cortex-M Prototyping System for MCU / SoC / ASIC designers working on Cortex-M processors. Key features: Altera Cyclone V FPGA with ~150K LE 4x 2MB ZBTRAM (32-bit each, with two of them forming a 64-bit memory). ZBT = Zero Bus Latency 16MB PSRAM (16-bit) Touch screen LCD module Range of hardware interfaces – UART, VGA (4 bit per color), SPI, audio (I2S), Ethernet, LEDs, buttons I/O expansion ports (GPIO) FPGA images for Cortex-M processors Example project for Cortex-M0 DesignStart (processor IP has to be licensed separately) USB connection for downloading FPGA images and program image to micro SD card on board […]
