Atmel® Corporation (NASDAQ: ATML), a global leader in microcontroller (MCU) and touch technology solutions, today announced that it is now in pilot production of products based on the industry’s lowest power ARM® Cortex®-M solutions. Power consumption has been reduced to 35µA/MHz in active mode and 200nA in sleep mode. This ultra-low power SAM L series broadens the Atmel|SMART 32-bit ARM MCU portfolio, extending battery life from years to decades, reducing And the number of battery changes required for devices located in rural, agricultural, offshore and other remote areas. The ultra-low power SAM L21 is also equipped with sufficient flash and SRAM memory to run applications and wireless stacks simultaneously, three features that are the cornerstones of most IoT applications. The SAM L21, now in pre-production, also comes with a development platform including the Xplained PRO suite, code library and Atmel Studio support.

This new family of products consumes only one third of the power consumption of similar solutions on the market today and integrates the company’s proprietary ultra-low power picoPower® technology. When running EEMBC® ULPBench™, the industry low-power reference standard, the SAM L21 achieved an astonishing score of 185, the highest score of any Cortex M-based processor in the world today, and significantly higher than the 143 and 123 announced by other vendors. point. Atmel’s SAM L21 series consumes less than 940nA with all 40kB of SRAM memory reserved, real-time clock and calendar functions active, and only 200nA in deepest sleep mode.

Atmel’s ultra-low power SAM L21 product family is ideal for a range of applications including Internet of Things (IoT), consumer electronics, industrial, medical and other battery powered devices. This innovation in low power consumption in this Atmel | SMART family of products is enabled by several technological breakthroughs, including:

The industry’s best operating mode current consumption.

·SRAM reverse bias technology to reduce leakage current in sleep mode.

·In sleep mode, it can not only stop switching power consumption by shutting off the isolated clock signal, but also avoid the power supply of sub-regions, and completely eliminate the leakage current.

· The SAM L21 peripheral supports Sleepwalking technology, which allows the peripheral to request a clock signal when it needs to wake up from sleep mode, and then perform the task without powering on the CPU flash memory and other supporting systems.

· Atmel’s proprietary event system function allows peripherals to work together to solve complex tasks, using only the minimum number of gates, to achieve the lowest possible power consumption.

· Ultra-low-power capacitive touch-sensing peripherals can work in all operating modes and dominate wake-on-touch.

“Our SAM L21 MCUs are helping customers solve the power consumption challenges faced by battery-powered IoT devices,” said Pat Sullivan, vice president of marketing for Atmel’s Microcontroller Group. “As a leader in low-power technology, Atmel is committed to bringing The industry offers truly differentiated and unmatched IoT-optimized ultra-low power solutions. When paired with Atmel’s wireless and security solutions, it provides the industry with the perfect IoT platform.”

Markus Levy, founder and president of EEMBC, said: “When Atmel released its SAM L21 product line last year, I praised its ultra-low current consumption in both active and sleep modes. After the L21’s EEMBC ULPBench score, I am more certain of my opinion. With Atmel’s own patented technology picoPower, they have broken through the low power consumption bottleneck of Cortex-M-based processors and controllers in the industry. This time ULPBench score It’s impressive and allows more people to see the company’s expertise in the low-power field and other innovative technologies.”

Evaluation Kit

To speed up the design process, the new SAM L21 series is compatible with Atmel Xplained Pro, a professional evaluation board that features automatic recognition when using Atmel Studio, an on-board debugger and standardized expansion headers. The Atmel® Xplained Development Kit is a low-cost, easy-to-use, rapid prototyping and evaluation platform for Atmel AVR® and Atmel | SMART ARM®-based MCUs. This set is ideal for demonstrating the features and capabilities of Atmel MCUs and MPUs, and can be customized with a wide range of expansion cards. The SAM L21 Xplained Pro is fully supported by Atmel Studio. Atmel Studio is a free IDE product that also includes a power analysis tool for the SAM L21 board, making it easy to locate power peaks and calculate average power consumption.

Pricing and Availability

The Atmel SAM L21 family is currently sampling, and to help you accelerate your design, development tools and data sheets are available at Product mass production is scheduled for September 2015.
