Atmel announced that it has expanded its popular security, ARM Cortex M0 + -based MCU family with the SAM L22 family. Atmel | SMART SAM L series is the highest scoring product series in EEMBC ULPbench, EEMBC ULPbench is the leading independent low power benchmark. The new device offers an ultra-low-power capacitive touch screen with a segmented LCD controller that can provide up to 320 segments, making it ideal for low-power applications, including thermostats, electricity / gas / Water meters, home control, medical and access systems.
The Internet of Things (IoT) is driving connectivity for a variety of battery-powered devices, giving these devices key features of security and ultra-low power consumption. The SAM L22 series provides advanced security features including 256-bit AES, cyclic redundancy check (CRC), true random number generator, flash protection and tamper detection to ensure secure storage, transfer and access to information. For the lowest power consumption, these devices use Atmel's proprietary picoPower technology and intelligent low-power peripherals that operate independently of the CPU in sleep mode.
"As more and more devices in the consumer, industrial, and home automation fields become more intelligent and connected, these devices require many unique features, including ultra-low power consumption, security, and touch functions with LCD- All the features that SAM currently offers. L22, "said Oyvind Strom, senior director of Atmel MCUs. "Atmel has worked with numerous alpha customers who have developed metering, thermostat and industrial automation solutions based on the new Atmel | SMART SAM L22 series."
In addition to segmented LCDs supporting up to eight communication lines, capacitive touch sensing In addition to built-in security measures, the SAM L22 series also features up to 256kB of flash memory and 32KB of SRAM, crystalless USB devices, programmable serial communication module (SERCOM) and Atmel's patented event system and sleepwalking technology.
To speed up design, the new SAM L22 Atmel Xplained Pro is now available-a professional evaluation board with an on-board debugger and standardized expansion connectors. The SAM L22 Xplained Pro is fully supported by Atmel Studio, a free IDE with a power configuration tool for the SAM L22 board that makes it easy to optimize applications and calculate average power consumption. The Atmel Xplained Development Kit is a low cost, easy to use, fast prototyping and evaluation platform for Atmel AVRR and Atmel. MCU based on SMART ARM. This kit is ideal for demonstrating the features and functionality of Atmel MCUs / MPUs and can be customized through various expansion boards.
