IoT

New legislation takes effect in 2024, mandating stricter requirements on cybersecurity on everything from consumer IoT devices to critical infrastructure. Meeting these new security compliance requirements from a product and supply chain perspective can be complex, costly and time-consuming. To provide developers with an embedded security solution that allows them to design applications that comply with these requirements, Microchip has announced the new family of PIC32CK 32-bit microcontrollers (MCUs) with an integrated Hardware Security Module (HSM) subsystem and Arm Cortex-M33 core featuring TrustZone technology to help isolate and secure the device.

The PIC32CK SG is the first 32-bit device on the market that combines the strong security of an HSM with TrustZone technology, a hardware-based secure privilege environment. Microchip’s latest innovation for mid-range MCUs provides designers with a cost-effective embedded security solution for their products that meets the latest cybersecurity mandates. The inclusion of an HSM provides a high level of security for authentication, secure debug, secure boot and secure updates, while TrustZone technology provides an additional level of protection for key software functions. The HSM can accelerate a wide range of symmetric and asymmetric cryptography standards, true random number generation and secure key management.

The PIC32CK MCUs from Microchip are designed to support ISO 26262 functional safety and ISO/SAE 21434 cybersecurity standards. For increased flexibility and cost efficiency, the PIC32CK MCU family offers a wide range of options to tune the level of security, memory and connectivity bandwidth based on the end application’s requirements. Options include up to 2 MB dual-panel Flash and 512 KB SRAM, with various connectivity options like 10/100 Ethernet, CAN FD and USB.

For product supply chains that require additional security and safety protection such as in industrial designs, medical devices, home appliances and consumer IoT devices, the PIC32CK will be supported with Microchip’s Trust Platform Design Suite for provisioning as a service. This platform enables the secure factory provisioning of keys, certificates and IP without the need to reveal these secrets within the supply chain.

The 32-bit PIC32CK MCU family is supported by Microchip’s software platforms including MPLAB® Harmony v3 and Trust Platform Design Suite. The PIC32CK family is also supported by the PIC32CK SG and PIC32CK GC Curiosity Ultra Development Boards including the EV33A17A and EV44P93A.

Insight SiP has launched its ISP5261 Wi-Fi 6 module at Embedded World 2024. This module acts as a fully functioning Bluetooth LE and Wi-Fi radio node, capable of a long autonomous operation on battery power. It can form the core of an autonomous IOT device requiring Bluetooth LE and Wi-Fi connectivity.

This device offers integration and miniaturisation of RF technologies, using System in Package technology. The device also benefits from Insight SiP’s proprietary “Antenna-in-Package” techniques.

The module is based on NXP Semiconductors RW612 single-chip Wi-Fi/Bluetooth LE/802.15.4 Wireless MCU System on Chip (SoC). The module integrates a 32-bit ARM Cortex-M33 CPU running at 260 MHz, additional 4 MB of QSPI flash memory, 1.2 MB SRAM as well as analog and digital peripherals. Its powerful processor and ample memory permit this module to be used as the core of a sophisticated IOT application.

Despite the small size of 12 x 12 x 1.8 mm, the module integrates decoupling capacitors, 40 MHz crystal for Wi-Fi and Bluetooth LE and 32.768 kHz crystal for low power timing, DC-DC converters, RF matching circuits and a dual-band (2.4 and 5 GHz) antenna. This module thus offers class leading performance and miniaturisation.

Low power consumption and advanced power management enable battery lifetimes up to several months on AA batteries. Wi-Fi communication is compliant with the Wi-Fi Alliance specifications for Wi-Fi 6 including the following protocols: IEEE 802.11ax/ac/n/a/g/b/e/i/k/v/w.

Bluetooth LE connectivity is compliant with Bluetooth 5.4, enabling Long Range communication. ISP5261 Bluetooth LE section can be used either in peripheral or central roles and can handle up to 16 simultaneous central/peripheral connections. Also supported are the Matter and Thread protocols, allowing easy internet access and support for SmartHome applications.

Security Features are prominent in the module, with an ARM TrustZone processor, and NXP Edgelock hardware security module, supporting Root of Trust, secure communication and update verification.
