Nordic integrates Bluetooth Smart and NFC Touch-to-Pair
Nordic Semiconductor has put Bluetooth Smart and NFC for Touch-to-Pair on its nRF52832 SoC which has a 64MHz ARM Cortex-M4F processor, a 2.4GHz multi-protocol radio, and automatic power optimisation.
According to Nordic Semi, with a 215 CoreMark the nRF52832 delivers up to 60% more generic processing power than competing products and, thanks to its ARM Cortex-M4F, up to an additional 10 times the floating point and twice the DSP performance. And at 90 CoreMark/mA the SoC is up to twice as power efficient as competing solutions, the company claims.
The SoC also includes on-chip peripherals for glueless interfacing to external components such as sensors, displays, touch controllers, LEDs, keypads, motors, digital microphones, and audio Codecs, making it suitable for wearables, remote controllers, toys, smart home devices and appliances, and wireless charging.
Development Kits, QFN samples, software and documentation are available. Volume production is scheduled for December 2015.
