恩智浦半导体宣布，Nordic Semiconductor已经在其最新的Bluetooth®低能耗参考设计中选用了恩智浦低功耗LPC1114微控制器。采用低功耗ARM® Cortex™-M0微控制器的恩智浦LPC1114具有Nordic nRF8001蓝牙连接IC所需的低能耗特性，而该IC主要用于无线鼠标和键盘的nRFready µBlue™台式机参考设计。采用Nordic低能耗参考设计仅需一对AA电池，即可支持无线鼠标和键盘连续使用超过一年和十年时间。
In addition, Nordic has introduced the LPC1114 Cortex-M0 microcontroller in its nRFready µBlue Smart Remote reference design for remote control of connected TVs and set-top-boxes. Bluetooth low energy technology enables a new ecosystem of battery-powered devices to interact with Bluetooth Smart Ready hosts, such as mobile phones, tablets, PCs, TVs and STBs, without the penalty of a large reduction in battery life. The ecosystem is expected to expand significantly within the next two years: ABI Research predicts that 2 billion Bluetooth-enabled devices will ship in 2012 and 3 billion in 2014.
“After an extensive comparison of popular low-cost microcontrollers, we concluded that NXP’s Cortex-M0 microcontroller was simply the best choice – delivering the high-performance system capabilities necessary to implement Bluetooth low energy, while meeting our stringent low-power requirements,” said Thomas Embla Bonnerud, director of product management, Nordic Semiconductor.
In the nRFready µBlue Desktop reference design, the LPC1114 microcontroller senses user inputs such as keystrokes, and controls and communicates with Nordic’s nRF8001 Bluetooth low energy connectivity radio, which transmits data wirelessly to a Bluetooth Smart Ready smartphone or PC. In the Smart Remote reference design, LPC1114 performs multi-tasking by detecting multi-touch inputs, sensing QWERTY keyboard strokes, calculating the 6-axis gyro inputs, and controlling the nRF8001 Bluetooth connectivity IC. Compared to typical Bluetooth solutions, the nRFready µBlue reference designs significantly reduce system power consumption at both the host and the devices.
“Nordic’s nRFready µBlue reference designs are making it easy to bring Bluetooth low energy computer peripherals and other devices to market quickly, and we’re pleased that our Cortex-M0 LPC1114 microcontroller is part of those designs,” said Jan Jaap Bezemer, director of marketing, microcontroller business line, NXP Semiconductors. “For emerging smart system implementations, NXP Cortex-M0 brings together an optimal combination of very low power and very low cost, along with 32-bit resources that enrich the end-user experience.”
