Overview

Description

 

nRF51422 是功能強大、高靈活性的多協議 SoC,非常適合使用於 ANT+ 和 2.4GHz 超低功耗無線應用。 nRF51422 根據配備 256KB flash + 16KB RAM 的 32 位元 ARM® Cortex™ M0 CPU 而建構。 嵌入式 2.4GHz 收發器支援 ANT 及專利 2.4GHz 運作,其中 nRF51422 與 Nordic Semiconductor 的 nRF24L 和 nRF24AP 系列產品無線相容。

nRF51422 還具備豐富的類比和數位周邊產品,可以在無需 CPU 參與的情況下透過可程式化周邊介面 (PPI) 系統進行互動。 靈活的 31 針腳 GPIO 映射方案可使 I/O(例如序列介面、PWM 和正弦解調器)根據 PCB 需求指示映射到任何設備針腳。 這可在關於針腳位置與功能方面,達成完全的設計靈活性。

nRF51422 支持 Dynastream Innovations 的嵌入式 S210 ANT 協定堆疊及 2.4GHz 協定堆疊(包括 Gazell),這兩種協定堆疊在 nRF514 軟體開發套件中均免費提供。nRF51422 需要單獨供電,如果供電範圍在 1.8-3.6V 之間,使用者可選擇使用晶片上的線性整流器,如果供電範圍在 2.1-3.6V 之間,可以選擇直流 1.8V 模式和晶片上的 DCDC 變壓器。DC-DC 變壓器的使用可在工作期間動態控制,並使 nRF51422 工作期間的射頻峰值電流低於 10 mA @ 3V 供電 (TX @ 0 dBm & RX)。

nRF51422 具有 48 引腳 6x6 QFN 封裝和 3.5x3.8mm 64 球形直接晶片構裝之晶圓級封裝 (WLCSP)。

Development Tools and Software

 

Nordic offers a range of HW and SW tools you can leverage to get you started evaluating and developing applications on your chosen nRF51 Series device. Please use the links below to learn more about the development tools and software that are available from Nordic and 3rd parties.

 

Nordic Hardware

 

The nRF51 Series development hardware is provided by the nRF51 DK development kit and the nRF51 Dongle. The nRF51 DK and nRF51 Dongle covers the nRF51822 and nRF51422 SoCs and supports Bluetooth Smart, ANT and 2.4GHz proprietary SW development. In addition you may download the recommended nRF51 reference layouts from the download tab on this page.

 

nRF51 DK

The nRF51 DK is a versatile single-board development kit offering access to all nRF51 Series IO through an Arduino UNO compatible socket or standard pin headers. nRF51 DK supports programming and debugging through both Jlink (Segger OB) and Mbed.
nRF51 DK 3D

For more information and relevant downloads, check out the nRF51 DK product page.

 

nRF51 Dongle

The nRF51 Dongle is a small USB dongle that have the same program and debug capabilities as the nRF51 DK. It's prime purpose is to interact with PC based development tools and utilities from Nordic that enables it to be used as a peer device for your prototype, a sniffer to monitor on air traffic or indeed as an ultra small development board in itself.

Reference layouts

Since the nRF51 Series devices all are SoCs for wireless communication, the quality of the PCB layout is of outmost importance to ensure good radio performance. Official nRF51 reference layouts can be found on the download tab of this page, and please do follow them closely to avoid dissapointments when testing or qualifying your product.

3rd Party Modules

You may find a wide range of pre-qualified modules based on nRF51 Series devices on our 3rd Party Module page if you don't want to spend time on the Radio design work and NRE costs to qualify a design for Bluetooth Smart and teleregulatory authorities (FCC, ETESI, MIC, TELEC).

 

SOFTWARE

 

By using nRF51 Series devices you get free access to pre-qualified Bluetooth Smart as well as ANT protocol stacks for use in your applications along with extensive libraries and application examples.

The software are split in two major parts: SoftDevices containing wireless protocol stacks; and the nRF51 Software Development Kit (SDK) forming a common application code base for all nRF51 devices.

 

SoftDevices

A SoftDevice is precompiled and linked binary software, implementing a wireless protocol. While it is software, you as an application developer have minimal compile-time dependence on its features. The unique hardware and software support framework, in which it executes, provides run-time isolation and determinism in its behavior. These characteristics make the interface comparable to a hardware peripheral abstraction with a functional, programmatic interface.

The SoftDevice Application Program Interface (API) is available to applications as a high-level programming language interface, for example, a C header file.

Please find documentation as well as all available Softdevices, for free download, on the download tab of this page.

nRF51 SDK

The nRF51 Software Development Kit (SDK) is your starting point for software development on the nRF51 Series. It contains source code libraries and example applications covering :

  • Wireless as well as application examples
  • Bluetooth Smart and ANT+ profiles
  • Nordic’s 2.4GHz proprietary stack Gazell
  • Libraries for all nRF51 peripherals
  • Bootloaders
  • Wired as well as Over the Air (OTA) FW upgrades
  • Selected RTOS examples
  • Serialization libraries of Nordic SoftDevices

 

The nRF51 SDK is built on the ARM® CMSIS standard and supports the following SW development tool chains:

 

nRF51 SDK is available on the download tab of this page.

Tools

 

In order to aid your product development with programming and test/debug, Nordic also offers a range of tools enabling you to interact with and monitor prototype/product:

Tools Description
nRFgo Studio PC tool allowing device programming and Radio performance tests on nRF51.
Master Control Panel

An peer device emulator that allows you to connect to, monitor and interact directly with the bluetooth services in your product. This is a great tool to check if your product identifies itself and its capabilities the correct way as well as testing how it responds to correct as well as incorrect actions in the peer device.

MCP is an application for Windows PC’s (using the nRF51-Dongle).

nRF Master Control Panel

A powerful generic tool that allows you to scan and explore your Bluetooth Smart devices and communicate with them.

nRF MCP is an application on Android.

ANTware A peer device emulator for the ANT protocol running on PC’s with the nRF51-Dongle. This is a great tool to check if your product identifies itself and its capabilities the correct way as well as how it responds to correct as well as incorrect actions in the peer device.
nRF Sniffer

If the communication with a 3 party Bluetooth Smart Ready peer doesn’t work as intended, the nRF Sniffer enables you to monitor all the on air traffic between you and the peer through link establishment, security negotiations to exchange of data.

Often the only way to find where communication breaks down, and logs from this tool will often be the first thing our support engineers will ask for if you enter a support case/request on MyPage regarding communication problems.

nRF51-BLE-Driver Windows dll linking the MCP with the nRF51 Dongle. Presents an API similar to our SoftDevices for a PC application, making it ideal to make your own PC based test and demo tools.
nRFjprog (part of nRF51 toolset installer) Command line utility enabling programming of nRF51 devices through Jlink programmers/debuggers.
Mergehex (part of nRF51 toolset installer) Since the Nordic SoftDevices comes as precompiled hex files, when adding your own application, you will have (at least) 2 hex files to program into an nRF51 in your production line. Some industrial programmers can’t handle this and mergehex is a command line utility enabling you to combine multiple hex files into one for these programmers.
JlinkARM (part of nRF51 toolset installer) Driver for jlink debuggers

Please find these tools on the download tab of this page.

Mobile Apps

 

Your products are of course likely to communicate with a mobile device or computer, indeed that may be the sole purpose of it. To enable this you will need to interact with the wireless stacks and features in the installed OS’s themselves or an APP installed on top of these OS’s.

To facilitate this part of the development, Nordic has a range of application examples and tools for all the main mobile operating systems. Please visit our Mobile Apps page to get started with your mobile device SW development.
