The nRF51822 WLCSP and nRF51422 WLCSP SoCs will offer the full functionality of their nRF51822 and nRF51422 QFN counterparts but in a 3.5 mm (length) x 3.8 mm (width) x 0.5 mm (height) WLCSP format that with a 13.3 mm2 footprint occupies 40 percent less board space. If the WLCSP SoCs are further used in conjunction with an integrated balun design available for the nRF51 Series from STMicroelectronics, the total board space saving compared to a conventional QFN and discrete component design can be as high as 80 percent.

The new nRF51822 WLCSP and nRF51422 WLCSP claims to be the world’s smallest Bluetooth low energy (including Bluetooth Smart) and ANT+ SoC solutions and are ideal for any application where space is constrained such as smart fashion and sports watches, wearable sports & fitness or medical sensors, portable smartphone appcessories, hearing aids, and smart cards.

Many of the products represent some of the fastest growing market segments within the ultra low power wireless industry today.

"One of the key features of ultra low power wireless is its ability to support coin cell operation for long periods of time," concluded Geir Langeland, Nordic Semiconductor’s Director of Sales & Marketing. "As the battery is often the largest single component of any wearable device or portable accessory, Nordic Semiconductor is reducing their physical achievable limits down to watch battery dimensions with the launch of these latest nRF51 Series WLCSP variants and that could support some very exciting new product developments."
