SAN JOSE, Calif., March 30, 2015 /PRNewswire/
-- Atmel® Corporation (NASDAQ: ATML), a
leader in microcontroller (MCU) and touch technology solutions,
today announced the company is sampling the industry's lowest power
ARM® Cortex®-M based solution with power consumption down to
35µA/MHz in active mode and 200nA in sleep mode. The ultra-low
power SAM L family broadens the Atmel | SMART 32-bit ARM-based MCU
portfolio and extends battery life from years to decades, reducing
the number of times batteries need to be changed in devices such as
fire alarms, healthcare, medical, wearable, and devices placed in
rural, agriculture, offshore and other remote areas. The SAM L21
combines ultra-low power with Flash and SRAM that are large enough
to run both the application and wireless stacks—three features that
are cornerstones of most IoT applications. Sampling now, the SAM
L21 comes complete with a development platform including an
Xplained PRO kit, code libraries and Atmel Studio support.
The new family consumes just one-third the power of competing
solutions on the market today and integrates the company's
proprietary ultra-low power picoPower® technology. While
running the EEMBC® ULPBench™, the industry marker for low power,
the SAM L21 achieves a staggering score of 185, the highest
publicly-recorded score for any Cortex-M based processor or MCU in
the world—and significantly higher than the 167 and 123 scores
announced by other vendors. Atmel's SAM L21 family consumes less
than 940nA with full 40kB SRAM retention, real-time clock and
calendar and 200nA in the deepest sleep mode.
Atmel's ultra-low power SAM L21 family is ideal for a number of
applications including the Internet of Things (IoT), consumer,
industrial, medical and other battery-powered devices. The
low-power innovations in this Atmel | SMART family is achieved
through several technological breakthroughs including:
- Best-in-class active mode current consumption.
- SRAM back biasing to reduce leakage in sleep modes.
- Sleep modes that do not only gate away the clock signal to stop
switching consumption, but also remove power from sub domains to
fully eliminate leakage.
- SAM L21 peripherals that support Sleepwalking—a technology that
enables peripherals to request a clock when needed to wake-up from
sleep modes and perform tasks without having to power up the CPU
Flash and other support systems.
- Atmel's proprietary Event System that allows peripherals to
work together to solve complex tasks using minimal gates and also
the lowest possible power.
- Ultra-low power capacitive touch sensing peripheral that can
run in all operating modes and supports wake-up on touch.
"With over two decades of MCU experience, ultra-low power
picoPower technology is part of Atmel's heritage, starting with our
AVR family. The SAM L21 MCUs leverage this ultra-low power
expertise and are enabling customers to solve their power
challenges for battery-powered IoT devices," said Pat Sullivan, Vice President of Marketing,
Microcontroller Business Unit, Atmel Corporation. "As the leader in
low-power technology, Atmel is committed to providing the industry
with a truly differentiated and unparalleled ultra-low power
solution optimized for the IoT. When paired with Atmel's wireless
and security solutions, they offer the perfect IoT platform."
"In Atmel's announcement last year for the company's SAM L21
family, I had pointed out the amazingly low current consumption
ratings for both the active and sleep mode operation of this
product family - now I can confirm this opinion with concrete data
derived from the EEMBC ULPBench," said Markus Levy, President and Founder, EEMBC.
"Atmel achieved the lowest power of any Cortex-M based processor
and MCU in the world because of its patented ultra-low power
picoPower technology. These ULPBench results are remarkable,
demonstrating the company's low-power expertise utilizing DC-DC
conversion for voltage monitoring, as well as other innovative
techniques."
Evaluation Kit
To accelerate a design, the new SAM L21 is compatible with the
Atmel Xplained Pro, a professional evaluation board featuring
auto-identification in Atmel Studio with an on-board debugger and
standardized extension connectors. Atmel® Xplained development kit
is a low-cost, easy-to-use, fast prototyping and evaluation
platform for Atmel AVR® and Atmel | SMART ARM®-based MCUs. The kit
is ideal for demonstrating the features and capabilities of Atmel
MCUs and MPUs and can be customized with a wide range of expansion
boards. The SAM L21 Xplained Pro is fully supported by Atmel
Studio, a free IDE that features power profiling tools for the SAM
L21 board, making it easy to pinpoint power peaks and calculate
average power consumption.
Pricing and
Availability
The Atmel SAM L21 family is sampling now. To accelerate a
design, development tools and datasheet are also available on
www.atmel.com. Production quantities are scheduled for September 2015.
