2.4GHz RF and Bluetooth Smart solutions for remote controls

 

Consumer electronics - Wireless makes it easy to find, manage and control content on connected devices

 

Consumers have never had so much choice in terms of digital content and services, or such a challenging time accessing it. The Nordic ultra-low power (ULP) wireless technology already installed in millions of wireless PC peripherals worldwide is the solution. In products such as connected (Internet-enabled) TVs, for example, it supports RF remote controls with advanced navigation features such as touchpads, touchscreens, and QWERTY keyboards, without suffering interference from bright light sources (e.g. LED TVs) that affect IR.

The Nordic competitive edge

 

Nordic Semiconductor's ULP wireless range provides attractive solutions for any consumer electronics device that would benefit from a wireless link by offering:

  • Class-leading battery lifetimes– Years of lifetime using regular AA or AAA cells
  • Ease-of-use– Works 'out-of-the-box' without complex pairing procedures
  • Multi-protocol SoCs - Single chip solutions capable of running more than one protocol on-chip, including Bluetooth Smart (previously called Bluetooth low energy) and ANT
  • Pin compatible SoCs - Drop-in replacement devices across different protocol platforms
  • Protocol/Application independence - Clear separation between application and protocol code
  • Robust wireless connectivity – Excellent co-existence performance with other popular 2.4 GHz wireless technologies such as Wi-Fi and Bluetooth
  • Attractive price point – Single chip solutions with low cost external Bill of Materials (BoM) supporting entry-level product pricing

 

 

Nordic offers the following wireless technologies for Consumer electronics

 

2.4GHz RF ICs

2.4GHz

If you have very specific application demands and no requirements for interoperability through standards such as Bluetooth Smart or ANT, then proprietary protocols sometimes provide the best alternative. When this is the case, 2.4 GHz proprietary solutions often offer the greatest flexibility, best power consumption, and lowest Bill of Material. Nordic provide the Gazell proprietary protocol to serve these applications.

 

Gazell is a freely distributed, simple to use, low-power protocol developed for use with Human Interface Devices (HID) peripherals. Gazell is designed for systems that have asymmetrical power consumption requirements where a central hub may have relatively relaxed power demand requirements while communicating with a number of peripheral devices that have much more stringent power efficiency needs. HID applications include mouse, keyboard, remote controls, presenters, and drawing tablets.

 

Bluetooth Smart

Bluetooth Smart

Bluetooth Smart is an exciting technology that is becoming a standard feature in PC's and mobile devices. Bluetooth Smart Ready devices form the hub of our personal area networks, these include smartphones and tablets as well as dedicated hub products. Bluetooth Smart devices are the peripheral sensors that typically capture data and relay data to and from the hubs. Bluetooth Smart profiles are already available for a range of different applications.

Nordic IC offering

 

nRF51 Series logo_main_black

The nRF51 Series is Nordic's latest generation of ULP wireless System on Chip IC's that again sets the benchmark in this field. The nRF51 Series is based on the 32 bit ARM Cortex-M0 CPU and Nordic's leading multiprotocol radio and supports Bluetooth Smart, ANT, and 2.4GHz proprietary solutions. Across the range pin-compatibility allows for drop-in replacement of device types where application requirements differ with no requirement for redesign of circuit layout. The innovative software architecture ensures an absolute separation between application code and protocol stacks, and enables you to maintain one code base for products using different wireless technologies.

 

The nRF24L Series SoCs are the most common solution for wireless PC peripherals in the market today. Based on an enhanced 8051 CPU and Nordic's radio technology, the nRF24L Series SoCs represent an extremely popular, cost-effective, and proven choice for PC peripheral development.
