主要参数

【nRF52832】

Advanced performance Bluetooth5/ANT/2.4GHz proprietary SoC

Active

The nRF52832 SoC is a powerful, highly flexible ultra-low power multiprotocol SoC ideally suited for Bluetooth® low energy (previously called Bluetooth Smart), ANT and 2.4GHz ultra low-power wireless applications. The nRF52832 SoC is built around a 32-bit ARM® Cortex™-M4F CPU with 512kB + 64kB RAM. The embedded 2.4GHz transceiver supports Bluetooth low energy, ANT and proprietary 2.4 GHz protocol stack. It is on air compatible with the nRF51 Series, nRF24L and nRF24AP Series products from Nordic Semiconductor.

Bluetooth 5

The nRF52832 has hardware support on-chip for Bluetooth 5. This includes high throughput and advertising extension.

Processing power

The nRF52832 incorporates a powerful Cortex-M4F processor enabling the most demanding applications with complex arithmetic requirements to be realized in a single chip solution. The IC supports DSP instructions, a Floating Point Unit (FPU), single-cycle multiply and accumulate, and hardware divide for energy-efficient process of computationally complex operations.

Multiprotocol radio

The 2.4GHz radio supports multiple protocols including Bluetooth Low Energy, ANT and 2.4GHz proprietary. The 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 Low Energy. ANT protocol stacks are available from ANT here: www.thisisant.com.

Power Efficiency

The nRF52832 SoC is an extremely power efficient device that can run from a supply between 1.7V and 3.6V. All individual peripherals and clocks offer complete flexibility of power down when not required for task operation thus minimizing power consumption to a minimum. The IC has a comprehensive system of automated and adaptive power management features. These features range across the entire IC’s operation from power supply switching to peripheral bus/EasyDMA memory management, to automated shut down of all but the absolute essential peripherals required to perform a task.

On-chip NFC tag

NFC™-A tag support is included on chip. Out-of-Band (OOB) pairing using NFC simplifies the process of authenticated pairing between two Bluetooth devices by exchanging authentication information over an NFC link.

Package options

The nRF52832 is available in 6x6mm 48-pin QFN packages and 3.0x3.2mm ultra-compact wafer-level chip-scale packages (WL-CSP).

SoftDevice

The nRF52832 is supported by the S132 SoftDevice, a Bluetooth 5 pre-qualified protocol stack. Click for more information on nRF52 Series in our Infocenter
