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 […]

Freescale Announces Availability of Kinetis L Series Cortex M0+ MCU and Freedom Devkit

ARM unveiled its ultra-low power Cortex-M0+ core back in March, and Freescale and NXP also announced their plans to use this new core in some of their micro-controllers destined to power the internet of things. Yesterday at Freescale Technology Forum (FTF), Freescale announced the availability of alpha samples of its Kinetis L series. This new low power MCU family will allow existing 8-bit and 16-bit architecture to be replaced by 32-bit architecture without increasing power consumption, cost or size, and the company expects them to be used in devices such as small appliances, gaming accessories, portable medical systems, audio systems, smart meters, lighting and power control. The ARM Cortex-M0+ processor is said to consume about a third of the energy of any 8- or 16-bit processor, while delivering between two to 40 times more performance. Kinetis L series MCU can consume as low as 50 uA/MHz in very-low-power run (VLPR) […]

ARM Announces ARM Cortex-M0+ Core to Power the Internet of Things

ARM has just unveiled the ARM Cortex-M0+ 32-bit processor optimized to deliver ultra low-power and low-cost MCUs to power the ‘Internet of Things‘ by controlling connected intelligent sensors and smart control systems in a broad range of applications including home appliances, white goods, medical monitoring, metering, lighting and power and motor control devices. ARM claims the Cortex-M0+ consumes just 9µA/MHz on a low-cost 90nm LP process, around one third of the energy of any 8- or 16-bit processor available today, while delivering significantly higher performance (1.77 CoreMark/MHz). Beside the low power consumption, the main advantage of the Cortex-Mo+ over 8-bit and 16-bit MCUs , is that it can provide low power wireless connectivity to a variety of embedded systems such as wireless sensors. The new processor is based on Cortex-M0 processor but has been redesigned to include a few new features such as: Single-cycle IO to speed access to GPIO […]
