The NHS52Sx4 family provides connectivity solutions for medical IoT applications. The NHS52Sx4 devices constitute a highly integrated, single chip, ultra-low-power Bluetooth® Low Energy 5.3 wireless transceiver with embedded microcontroller and flash.
Because of the integrated ultra-low-power radio and flash, the NHS52Sx4 provides extended battery lifetime. The NHS52Sx4 is a cost-effective solution within a small solution area required for body-worn sensors and actuator applications like smart skin patches, smart inhalers and vital signs monitoring.
The NHS52Sx4 family supports a versatile range of battery types ranging from silver oxide, Li-ion coin cell to PMIC-based product architectures.
Built with advanced security in mind, the NHS52Sx4 devices are part of NXP EdgeLock® Assurance program.
NHS52Sx4 and enablement (documentation, software and boards) are available for select customers with an approved NDA. For additional information and sample availability, contact support or your local sales representative.
