Security is taken seriously at Nordic Semiconductor, which has introduced the nRF5340 SoC, with Arm CryptoCell-312, Arm TrustZone technology and Secure Key Storage for the highest level of security, says the company. The most common internet encryption standards are hardware accelerated with the Arm CryptoCell-312, while Arm TrustZone provides system-wide hardware isolation for trusted software by creating secure and non-secure code execution areas on a single core. The nRF5340’s combined security features enable advanced root-of-trust and secure firmware updates while protecting the SoC from malicious attack, claims Nordic Semiconductor.

Interface module enables MEMS microphone array testing
Audio Precision has introduced a PDM 16 module for the company’s APx500 Series audio analysers. The module offers simultaneous acquisition and measurement of up to 16 channels of pulse density modulation (PDM) signals, making it the highest channel-count solution available for MEMS microphone and MEMS mic array testing, claims the company.
Evaluation kit supports energy harvesting embedded controller
For the development of battery maintenance-free IoT equipment, Renesas Electronics has introduced the RE family, which encompasses the company’s current and future line-up of energy harvesting embedded controllers. The RE Family is based on Renesas’ proprietary Silicon on Thin Buried Oxide (SOTB) process technology. SOTB is claimed to dramatically reduce power consumption in both active and standby states, eliminating the need for battery replacement or recharging.
High-side load switch uses reverse current blocking to improve reliability
The AP22912 is a 2.0A single-channel, slew rate-controlled load switch from Diodes. It has true reverse current blocking (TRCB) for high-side load-switching applications.
