Meet Freescale Kinetis KL03, the Smallest Ever ARM MCU

Last year at Embedded World 2013, Freescale announced Kinetis KL02, an ARM Cortex M0+ MCU measuring just 1.9 x 2.0mm. Customer must have complained that it’s not small enough, as the company has just unveiled Kinetis KL03 MCU, 15% smaller or 1.6 x 2.0 mm, at Embedded World 2014. Just like its predecessor KL03 targets space-constraint IoT applications such as ingestible healthcare sensing, portable consumer devices, remote sensing nodes, and wearable devices.   Kinetis KL03 MCU features include: 48 MHz ARM Cortex-M0+ core, 1.71-3.6V operation Bit manipulation engine for faster, more code-efficient handling of peripheral registers 8 to 32 KB flash memory, 2 KB RAM, 8K ROM with on-chip boot loader High-speed 12-bit ADC Internal voltage reference for high ADC accuracy High-speed analog comparator Up to 22 GPIOs with pin interrupt support Low-power UART, SPI, I2C (high speed) Low power wake up Secure real time clock Timers for a broad range of […]

Atmel Adds SAM D21, D10 and D11 MCUs to Its ARM Cortex M0+ SAM D Family

Atmel launched SAM D20 MCU family based on ARM Cortex M0+ last year, and at Embedded World 2014, the company has launched three new MCU families featuring ARM ultra low power core with SAM D10, SAM D11, and SAM D21 families and their corresponding Xplained PRO development boards. Atmel four SAM D  families target different applications and price points: SAM D10 – The smallest member of the SAM D family in terms of memory, pin count, and features. SAM D11 – Adds full-speed USB not available on the SAM D10. SAM D20 – “Offers a rich set of peripherals, flexibility, and ease-of-use with low power consumption.” SAM D21 – Adds features such as full-speed USB, DMA, high-end timers/counters to D20 design. I’ve compared the four families in the table below: SAM D10 SAM D11 SAM D20 SAM D21 # MCU in Family 4 4 15 12 MCU Core ARM Cortex-M0+ […]

Atmel Introduces ARM Cortex M0+ based SmartConnect Wi-Fi Modules and SmartConnect Zigbee SoCs

In order for the Internet of Things to take off, wireless connectivity solutions with ultra low power, lost cost, and small footprint are needed. Atmel seems to have made a step in the right direction by launching SmartConnect Wi-Fi modules and Zigbee SoCs featuring an ARM Cortex M0+ core. SmartConnect Wi-Fi does not appear to be a single chip solution, but instead Atmel has created a family of Wi-Fi modules integrating the company’s ultra-low power Wi-Fi SoChip with an ARM Cortex M0+ based MCU. These modules will enabled battery-powered Wi-Fi connectivity for IoT endpoints such as thermostats, and temperature sensors in a cost effective way. The company will provide a software solution with application and security protocols such as TLS, TCP/IP stack and an RTOS, all of which can be downloaded via Atmel Studio 6 Integrated Development Platform (IDP). SmartConnect ZigBee SAM R21 combines an ARM Cortex M0+ core with […]

802.11ah Wi-Fi (900 MHz) to Provide Low Power, Long Range Connectivity for the Internet of Things

Most devices now feature Wi-Fi modules capable of handling 802.11 b/g/n at 2.4 Ghz (and 5 GHz for dual band Wi-Fi), and newer devices and routers boast 802.11ac connectivity @ 5GHz with increased bandwidth (up to 1.2 Gbit/s in theory, maybe around 400 Mbit/s in practive), and in some case increased range with  beam-forming. But thanks to an article on EETimes, I’ve learned there’s another upcoming Wi-Fi standard called 802.11ah operating in the 900MHz range, with data rates from 150 Kbit/s with a 1 MHz band to as much as 40 Mbit/s over an 8 MHz band, lower power consumption, and a least double of the range of a typical 802.11n device,capable of covering an area of about 1 km2. The target applications are sensors networks, backhaul networks for sensor and meter, and extended range Wi-Fi, as the standard allows long range and more clients at low bitrates. This new […]

Fin is a Bluetooth Ring That Let You Control Your Devices with Your Fingers (Crowdfunding)

We’ve already seen smart rings with NFC rings that can be used for authentication and share small amount of data (e.g. business card data) with smartphones. Fin is a completely different type of smart ring that fits onto your thumb, and let you control Bluetooth enabled devices by tapping different phalanges on your fingers, and/or the palm of your hand. Here are some of Fin smart ring specifications: MCU – N/A Connectivity – Bluetooth 2.1 + EDR, and 4.0 Sensors – No details, but Fin can track accurate movement of your thumb on the palm and detect each phalanx of your finger where you are touching. IP Rating – IP67 (Dust and Waterproof) Battery –  Li Po custom battery with micro-USB charging dock ; One charge will last for 1 week; more than one year durable. Misc – LED indicator The ring will work with Windows, Mac, iOS, Android, and Windows […]
