Fitness trackers and smart keys to chains, watches or wristbands are increasingly including mobile payment functionality, needing them to be equipped with security and NFC technologies. Infineon has launched an NFC security module series in collaboration with Beijing-based Mobile Payment Solutions (MPS). It is claimed to “significantly” reduce design efforts by bundling an Infineon security chip with NFC antenna components and software on a small PCB footprint. The smallest module of the series measures only 4.0 x 4.0mm.

NXP’s Bluetooth SoCs and development kit, shipping from Mouser Electronics
Low-power Bluetooth SoCs, the QN902x series, and the QN9020 Bluetooth development kit, by NXP Semiconductors, are available from Mouser Electronics. The integrated, ultra-low-power Bluetooth v4.0 Low Energy (BLE) SoCs can be used for Bluetooth Smart applications such as sports and fitness wearables, human interface devices, and app-enabled smart accessories. They integrate a high-performance 2.4GHz RF transceiver with a 32bit ARM Cortex-M0 microcontroller, 128kbytes of flash memory, and 64kbytes of system memory. In addition to the BLE radio and microcontroller, the SoCs incorporate the BLE protocol stack and profile software on a single chip.
Bluetooth Smart sensor development kit targets virtual reality
Targeting IoT and virtual reality (VR) applications, what is claimed to be the world’s lowest power wireless smart sensor development kit has been released by Dialog. It comprises the company’s DA14583 SmartBond Bluetooth Smart SoC, combined with Bosch Sensortec’s gyroscope, accelerometer, magnetometer, and environmental sensors on a small PCB that measures just 16 x 15mm.
MCUs boost efficiency to energy-sensitive devices
Volume production has begun for the energy-efficient ARM Cortex-M0+ STM32L0 microcontrollers. There is a development ecosystem including minimal-cost boards and free software tools.
