Bluetooth Smart SoC with NFC tag

22 July 2015 Telecoms, Datacoms, Wireless, IoT

Nordic Semiconductor is sampling the first member of its next-generation nRF52 ultra-low-power wireless solutions. The nRF52832 system-on-chip (SoC) represents a single-chip solution for Bluetooth Smart connectivity, and uniquely features an on-chip NFC (near-field communications) tag for consumer friendly touch-to-pair functionality.

The device features a 64 MHz ARM Cortex-M4F processor that achieves an EEMBC 215 CoreMark score and 90 CoreMark/mA; 512 KB Flash and 64 KB RAM memory; and a multi-protocol Bluetooth Smart, ANT and proprietary 2,4 GHz radio with -96 dB receive sensitivity, 5,5 mA peak RX/TX currents, and an on-chip RF balun. A fully automatic power management system also makes achieving optimal power consumption easy for designers.

Built on a cutting-edge 55 nm process, the nRF52832 includes 6 x 6 mm QFN and 3,0 x 3,2 mm CSP packaging options. It integrates an assortment of on-chip analog and digital peripherals for glueless interfacing to external components such as sensors, displays, touch controllers, LEDs, keypads, motors, digital microphones and audio codecs. These features make it an ideal single-chip solution for wearables, human interface devices such as remote controllers, toys, smart home devices and appliances, and wireless charging.

Boasting on-air compatibility with Nordic’s nRF51, nRF24L and nRF24AP series, the new chip’s radio has high-definition RSSI and highly automated functionality, including EasyDMA for direct memory access during packet send and retrieve. Nordic provides protocol stacks for Bluetooth Smart, ANT and Gazel (2,4 GHz) as software downloads. NFC-A tag support is included on chip, and out-of-band pairing using NFC simplifies the process of authenticated pairing between two Bluetooth devices by exchanging authentication information over an NFC link.

The onboard Cortex-M4F processor supports DSP instructions, a floating point unit (FPU), single-cycle multiply and accumulate, and hardware divide for energy-efficient processing of computationally complex operations. The SoC can run off a supply between 1,7 V and 3,6 V, and all individual peripherals and clocks can be powered down when not required for task operation. A number of automated and adaptive power management features are also provided.
