NXP launches its first MCU to feature Arm TrustZone security technology

The LPC5500 series of microcontrollers from NXP Semiconductors features the recently introduced Arm® Cortex®-M33 core, which supports the renowned TrustZone security technology used widely in Arm A-class processors. TrustZone technology is approved by the banking industry to support secure financial operations.

Other security features in the LPC5500 MCUs include SRAM physically unclonable function-based root of trust and provisioning, and real-time execution from encrypted images in internal Flash memory.







New LoRaWAN expansion software for STM32 MCUs

STMicroelectronics has released a new I-CUBE-LRWAN expansion software package which enables STM32 microcontrollers to support the LoRaWAN™ low-power wide-area networking protocol. The package consists of a set of libraries and application examples for STM32L0, STM32L1 and STM32L4 series MCUs acting as end nodes.

The ST software is compatible with various LoRa® radio expansion boards provided by Semtech.







Bluetooth 5.0-compliant SoC from Microchip enables immersive audio

Microchip has introduced a fully certified System-on-Chip (SoC) which features Sony’s LDAC audio codec technology and a Bluetooth® 5 radio, giving OEMs a means to provide high-resolution audio in massmarket Bluetooth wireless products. Microchip supplies the IS2064GM-0L3 SoC in an 8mm x 8mm LGA package. It is available in production volumes.
