Wireless solutions combine high performance and power efficiency

Mouser is now stocking the nRF52 Series systems-on-chips (SoCs) from Nordic Semiconductor. These next-generation ultra-low-power radio frequency (RF) wireless solutions combine high performance and power efficiency, feature a unique on-chip NFC tag, and offer high levels of Bluetooth Smart design flexibility for a variety of applications, including Internet of Things (IoT), wearables, wireless charging, beacons, sports and fitness sensors, remote-controlled toys, and building automation. The SoCs feature a 64MHz ARM Cortex-M4F processor with 512kBytes of flash memory and 64kBytes of RAM, plus on-chip analog and digital peripherals. The SoCs also include a multiprotocol Bluetooth Smart, ANT, and proprietary 2.4GHz radio with -96dB RX sensitivity, 5.5mA peak RX/TX currents, and an on-chip RF balun. The devices’ fully automatic power management system reduces power consumption by up to 80 percent compared with the nRF51 Series. However, the nRF51 and nRF52 Series share a common software architecture (which separates the Bluetooth Smart RF software and customer application code), allowing designers to easily reuse proven legacy software. For cost-effective Bluetooth Smart modules with integrated high-performance antennas, Mouser also stocks the new EYSHCNZXZ Bluetooth Smart module from Taiyo Yuden, which features Nordic’s nRF52832 SoC. The module is a fully tested Bluetooth Smart solution compatible with the latest version of the Bluetooth Core Specification (v4.2), which can simplify the design of a wide range of connected products where performance, small size, and low power consumption are key factors. The device offers a high-performance ceramic chip antenna, 30 general-purpose input/outputs, as well as SPI, UART, I2C, I2S, PDM, and 12-bit analog-to-digital converter interfaces together with analog inputs. The module’s output power is adjustable up to +4dBm, and its compact 9.6mm × 12.9mm × 2mm form factor makes it suitable for a variety of small, thin devices, including healthcare equipment, wearable devices, and smartphone peripherals.
