【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

Nordic Semiconductor公司宣布提供其nRF52832低功耗蓝牙(Bluetooth® low energy) (前称为蓝牙智能)系统级芯片(SoC)的晶圆级芯片尺寸封装(WL-CSP)产品,占位面积为标准封装nRF52832器件的四分之一,为瞄准新一代高性能可穿戴产品而设计。

与体积较大但封装简便、具标准6.0 X 6.0mm占位面积的nRF52832 QFN48器件相比,nRF52832 WL-CSP器件具有超紧凑3.0 X 3.2mm占位面积,并提供相同的全功能单芯片特性集和同级最佳超低功耗应用运作; 其功能强大的板载64MHz ARM® Cortex®-M4F处理器能够在前所未有的短时间内完成协议和应用任务的处理,使得它能够在比其它竞争对手的器件更短时间内进入睡眠模式以节省功率。

nRF52832 WL-CSP器件与nRF52832器件同样具有512kB闪存和64kB RAM;用于消费者友好的触摸配对(Touch-to-Pair)片上NFC™ 标签;同级最佳超高性能;超低功耗多协议低功耗蓝牙、ANT™,以及专有2.4GHz无线电、5.5mA峰值RX/TX电流,以及片上RF 巴仑;还有方便设计人员实现最佳功耗的独特全自动功率管理系统。

nRF52832 WL-CSP器件兼容Nordic的蓝牙4.2堆栈并支持SDK,包括最新S132多用途并行软件堆栈、nRF5 SDK、nRF5 SDK for HomeKit 和用于谐振无线充电的nRF5 SDK for Airfuel。

Nordic Semiconductor超低功耗无线产品经理Kjetil Holstad评论道:“超紧凑占位面积nRF52832器件面世,为可穿戴产品和其它空间受限IoT应用带来了全新的设计机会,这款SoC器件现在进行批量生产,可立即用于即将进行的产品开发中。迄今为止,可穿戴产品的演进仅有一个进化方向:日益增加的性能和功能性,以及日益纤细而且更轻巧的外形尺寸。nRF52832 WL-CSP器件明显是现今市场上最小并且最先进的低功耗蓝牙SoC器件。”

nRF52832 WL-CSP器件现已批量生产。
