nRF52832 SoC’s ARM M4F microprocessor provides ample computational power to run complex sensor algorithm and low latency Bluetooth Low Energy wireless connectivity in CyweeMotion’s ‘VRRM01’ virtual reality remote module.
The VRRM01 remote module employs a 200 mAh Li-Poly battery that can provide over 40 hours of continuous game time―or 200 days in standby mode―between recharge, thanks in part to the ultra low power characteristics of the nRF52832 SoC. The SoC has been engineered to minimize power consumption with features such as the 2.4GHz radio’s 5.5mA peak RX/TX currents and a fully-automatic power management system that reduces power consumption by up to 80 percent compared with Nordic’s nRF51 Series SoCs. The result is a Bluetooth LE solution which offers 58 CoreMark/mA, up to twice as power efficient as competing devices.
Nordic’s nRF52832 Bluetooth LE SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines a 64MHz, 32-bit ARM® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™ and proprietary 2.4GHz RF software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM. When launched, the SoC was the world’s highest performance single-chip Bluetooth LE solution, delivering up to 60 percent more generic processing power, offering 10 times the Floating Point performance and twice the DSP performance compared to competing solutions and making it a good choice for complex, computationally-demanding applications such as CyweeMotion’s VR motion controller.
“We chose the nRF52832 SoC for our VRRM01 design because its highly-efficient ARM Cortex M4F processor has the capability to run our sensor fusion algorithm in a more efficient way,” says Max Lin, VP of Sales, CyweeMotion. “And Nordic’s unique software architecture separates the S132 SoftDevice [Bluetooth LE RF protocol ‘stack’] from application code development bringing flexibility and reliability to application software development.
“Nordic’s proven hardware and software architecture has allowed us to focus on our core capabilities and ideas without the need for deep knowledge of Bluetooth LE wireless connectivity.”
