Atmel Delivers Industry's Lowest Power ARM Cortex-A5-based MPU with Leading Security Features for Industrial IoT and Wearable Applications

Atmel Corporation ATML, +0.06% a global leader in microcontroller (MCU) and touch solutions, today launched a new series of Atmel | SMART ARM® Cortex®-A5-based microprocessors (MPUs), delivering the world's lowest power consumption for all MPUs in its class. The new MPUs deliver sub 200uA in retention mode with context preserved, 30us ultra-fast wake-up and a new backup mode with DDR in self-refresh at only 50uA. The Atmel | SMART SAMA5D2 series provides great system integration with the addition of a complete audio subsystem, lower pin-count and ultra-small package for space constraints applications, and built-in PCI-level security targeting industrial Internet of Things (IoT), wearables and point of sale (POS) applications.

Expanding the Atmel SAMA5 family, the SAMA5D2 series delivers just the right price-to-performance ratio for applications requiring an entry-level MPU and extended industrial temperature range (-40 to 105°C ambient temperature). The new series is also a great migration path for designers using ARM926-based MPUs looking for higher performance and additional features including low power, higher security, DDR3 support, smaller footprint, audio, USB HSIC and Atmel's patented SleepWalking™ technology.

"As a leader in ultra-low power MCU and MPU IoT solutions, we are excited to launch the new Atmel | SMART SAMA5D2 series for designers requiring a general, entry-level MPU," said Jacko Wilbrink, Sr. Director of MPUs, Atmel Corporation. "Designers for industrial IoT, wearables and POS applications are demanding more performance, lower power, smaller form factors and additional security for their next-generation applications. The Atmel SAMA5D2 is well positioned for these demanding requirements, delivering the world's lowest power MPU, along with low-system cost and PCI level security."

Featuring an ARM NEON™ engine, the new SAMA5D2 series delivers 500MHz and 166MHz of system clocking. The memory system includes a configurable 16- or 32-bit DDR interface controller, 16-bit external bus interface (EBI), QSPI Flash interface, ROM with secure and non-secure boot solution, 128kB of SRAM plus 128kB of L2Cache configurable as SRAM extension. The user interface system for the SAMA5D2 includes a 24-bit TFT LCD controller, an audio subsystem with fractional PLL, multiple I2S and SSC/TDM channels, a stereo class D amplifier and Digital microphone support.

The robust security system in the new SAMA5D2 includes the ARM® TrustZone® technology, along with secure boot, hardware cryptography, RSA/ECC, on-the-fly encryption/decryption on DDR and QSPI memories, tamper resistance, memory scrambling, independent watchdog, temperature, voltage and frequency monitoring and a unique ID in each device.

SoftwareTo support the new series of SAMA5D2 MPUs, Atmel® has developed a free Linux® distribution available on www.Linux4sam.com and published in the mainline kernel. For non-operating system (OS) users, Atmel delivers more than 40 peripheral drivers in C. Atmel collaborates with a global network of partners, including IAR, ARM, Free Electrons, Active-Semi, Micron, ISSI, Winbond, Segger, Lauterbach, FreeRTOS, Express Logic, NuttX and Sequitur Labs, that deliver development tools, PMIC, memories and software solutions.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
