Nordic Semiconductor revealed that it is sampling the first member of its next-generation nRF52 family of ultra-low-power wireless solutions-the nRF52832 system-on-chip (SoC). nRF52832 combines the performance of breaking through obstacles with energy efficiency to redefine the single-chip Bluetooth Smart category. The company also stated that it also has a unique on-chip NFC tag that enables consumer-friendly "point-to-point" touch and offers new design flexibility that is unmatched by any existing Bluetooth Smart solution.
Thomas Embla Bonnerud, Nordic Semiconductor Product Director, said: "The current single-chip Bluetooth smart solution is struggling to keep up with the innovation speed of Bluetooth smart, which is the fastest growing wireless market in history, especially in wearables and the Internet of Things. Applying. "Management. "The main reason is that so far, higher performance can only be achieved at the expense of power efficiency. NRF52832 is characterized by: the first 64MHz ARM Cortex-M4F processor in the category; nRF52832 series has unique breakthrough performance and power efficiency .512kB flash memory and 64kB RAM; first-class ultra-high performance, ultra-low power multi-protocol Bluetooth Smart, ANT and proprietary 2.4GHz radio, with -96dB RX sensitivity, 5.5mA peak RX / TX current, and on-chip RF Balun. The novel fully automatic power management system also makes it easy for designers to achieve optimal power consumption. The nRF52832 is built on an advanced 55nm process and includes 6mm x 6mm QFN and miniature 3mm x 3.2mm CSP package options.
Compared to the competitor's ARM Cortex-M0 / M3, nRF52832 has an EEMBC 215 CoreMark score, which can provide up to 60% of general processing power-coupled with the on-chip ARM Cortex-M4F, its floating point number is increased by 10 times, and the DSP The performance is improved by 2 times. Bluetooth-based smart SoC solution. The SoC has a power efficiency of 90 CoreMark / mA, which is twice that of similar solutions. nRF52832 also includes complete on-chip analog and digital peripherals that can seamlessly connect with external components such as sensors, displays, touch controllers, LEDs, keyboards, motors, digital microphones and audio codecs. This makes it an ideal single-chip solution for wearable devices, human-machine interface devices (such as remote controls, toys, smart home devices and appliances), and wireless charging.
The higher processor performance of the nRF52832 enables developers to make their products more attractive to consumers, including adding new features and improving the user experience. Single-chip integration supports smaller products and lower BOM. Higher energy efficiency supports longer battery life and / or uses smaller, lighter batteries, and makes nRF52832 an ideal solution for energy harvesting-powered applications. Best-in-class radio performance supports up to 2x connection reliability, robustness to interference, range, and data throughput, all of which minimize packet loss and technical support issues, and improve network topology and protocol Complexity and advanced security features.
Bonnerud continued: "With the release of the nRF52832, the first product of the nRF52 series, we are constantly working to achieve the limits that a single-chip Bluetooth Smart can achieve." Requires the processing power and performance we now package in this chip Applications have so far had to use a two-chip solution, as there was no previous Bluetooth smart single-chip alternative. Nordic Semiconductor's nRF52832 is a single chip urgently needed in the Bluetooth Smart market, and we hope that it will allow developers to free up more creativity when developing Bluetooth Smart products and applications.
