Nordic Semiconductor's nRF51422 WLCSP ANT System-on-Chip
The nRF51422 wafer level chip scale package (WLCSP) is the world’s smallest ANT+ SoC. The chip provides ultra low power (coin cell) wireless connectivity using the proven ANT RF software protocol for compact wearable electronic sensors and devices such as smart watches, hearing aids, and smartcards.
Measuring 3.5 by 3.8 by 0.5mm (13.3mm2 footprint) the chip occupies 40% less board space than a QFN equivalent. When used in conjunction with a balun from STMicroelectronics, the total space saving are as high as 80%.
The nRF51422 WLCSP’s architecture includes low power radio, 32-bit ARM Cortex-M0 processor and 256kB flash + 16kB RAM. RX sensitivity is -96dB at 250 kbit/s and -85dBm at 2Mbit/s, and the device exhibits 13mA RX peak (at 1Mbit/s), 10.5mA TX peak (at 0dBm) and microamp average current from a 3V coin cell.
I agree. The slide show and technologies presented where awesome. I was really intrigued with Analog Devices wireless machine monitoring products. I can truly see an automation manufacter using their product to create and industrial internet thus having all machine peformance data available via the cloud. Great slides Lauren!
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
