Nordic Semiconductor introduced the first members of its new nRF51 Series of ultra-low power (ULP) RF integrated circuits (ICs) that feature a new multi-protocol 2.4-GHz radio and a 32-bit ARM Cortex-M0 based processor. The company’s software architecture for Bluetooth low energy and ANT System-on-Chip (SoC) solutions is said to free designers from the integration effort, complexities, and restrictions of chip vendor-supplied software frameworks and instead allows customers to develop their designs using the ARM Cortex programming environment. The new software architecture features a unique and powerful separation between protocol stack and user application code. This separation provides developers a clean boundary between application and protocol stack, and removes the need to struggle with integration of application code as part of a vendor-imposed application development framework. Code development is asserted to be greatly simplified and accelerated. At the same time, risks associated with integration of application and stack code are said to be significantly reduced. Customers can expect lower bug rates and improved robustness for their applications, according to the company.
