原标题：用于学生和老人的多协议先进智能卡同时提供支付宝支付和门禁解决方案

　　天波教育“随手精灵”智能卡采用Nordic多协议nRF52810 SoC，提供并发低功耗蓝牙和2.4GHz无线连接。

　　挪威奥斯陆– 2019年8月19日 – Nordic Semiconductor宣布总部位于广东的校园智能硬件开发商广东天波教育科技有限公司(TelpoEdu)已经选择使用Nordic的nRF52810低功耗蓝牙 (Bluetooth Low Energy /Bluetooth LE)系统级芯片(SoC)，为其 “随手精灵” 智能卡提供无线连接功能。该智能卡支持电子商务巨头阿里巴巴开发的支付宝支付平台，主要为学生和老人提供先进支付及门禁应用。

　　“随手精灵”智能卡同时具有低功耗蓝牙和2.4GHz专有无线连接功能。Nordic SoC提供低功耗蓝牙连接，使得学生能够将智能卡与其蓝牙4.0(及更高版本)智能手机配对使用，通过天波app配置智能卡用于支付宝动态离线支付平台。一旦智能卡链接到用户的支付宝账户，零售商就可以扫描卡上的二维码或条形码，自动从学生的账户中扣除金额。多协议nRF52810 SoC还支持并发2.4GHz专有无线连接，并与天波信息的门禁控制系统一起使用，可将智能卡用作学校和大学校园的楼宇门禁卡，2.4GHz专有门禁技术已广泛用于校园。

　　这片智能卡采用CR2032纽扣电池供电，在每次更换电池后提供较长的电池使用寿命，这部分归功于Nordic SoC的低功耗特性。经设计最大限度地降低功耗的nRF52810 SoC器件具有2.4GHz无线电的4.6mA峰值RX/TX电流等特性，而且其全自动电源管理系统可将功耗降低至比Nordic nRF51系列SoC还要低80%。

　　Nordic nRF52810多协议SoC结合了一个64MHz的32位Arm CortexM4处理器和2.4GHz多协议无线电(支持蓝牙5、ANT和专有2.4GHz RF协议软件)，具有192kB闪存和24kB RAM，以及先进的128位AES加密功能。nRF52810 SoC随附最新版本Nordic S112 迭构，这是符合蓝牙5标准的RF协议软件。

　　广东天波信息技术股份有限公司旗下子公司广东天波教育科技的项目总监颜斌表示：“我们选择使用nRF52810 SoC 的原因在于其安全功能、Nordic低功耗蓝牙堆栈的稳定性，以及并发低功耗蓝牙和2.4GHz专有连接支持，这对于同时用作支付解决方案和门禁卡的智能卡是至关重要的。我们先前使用的Nordic芯片以及Nordic软件开发套件[SDK]帮助我们削减了开发成本。”

【 nRF52810 】

High performance, entry-level Bluetooth 5/ANT/2.4GHz SoC

The nRF52810 is a high performance multiprotocol SoC supporting Bluetooth 5, ANT and 2.4GHz proprietary applications. It has been designed to offer advanced features such as Bluetooth 5 and an ARM Cortex-M4 CPU at a level that makes it compelling for even the lowest cost Bluetooth Low Energy applications. Together with the nRF52840 and nRF52832, the nRF52810 completes the nRF52 Series SoC range, giving developers a broad selection of features, memory variants and small-footprint package options.

nRF52810

The nRF52810 has hardware support on-chip for Bluetooth 5. This includes high throughput (2Mbps) and advertising extensions. Bluetooth 5 improved coexistence features are also supported. Find out more about Bluetooth 5.

Processing power

The nRF52810 incorporates a powerful ARM Cortex®-M4 processor enabling the most demanding applications with complex requirements to be realized in a single chip solution. It also enables all protocol handling to be executed in the shortest timeframe, thus enabling faster return to sleep and current saving ability.

Multiprotocol radio

The 2.4GHz radio supports multiple protocols including Bluetooth Low Energy (Bluetooth 5), 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 receive. Nordic provides protocol stacks for Bluetooth LE. ANT protocol stacks are available from ANT.

Power Efficiency

The nRF52810 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, and automated shut down of all but the absolute essential peripherals required to perform a task.

Package options

The nRF52810 is available in 6x6mm QFN-48 and 5x5mm QFN-32 packages

SoftDevice

The nRF52810 is supported by the S112 SoftDevice, a Bluetooth 5 pre-qualified Bluetooth LE protocol stack. Click for more information on nRF52 Series in our Infocenter.
