New module supports leading RF technologies and AI

Insight SIP is launching the ISP2554-HM module. This module represents a dynamic IoT node, with support for BLE, Thread, and Zigbee radios and high-performance computing including an ability to run AI at the Edge. It can form the core of a complex IoT device with an unparalleled mixture of features, performance and low power consumption. These features and antennas fit into this ultra-miniature RF module, a tiny package measuring only 9mm x 9mm x 1mm, the smallest on the market.

With an extended temperature capability of up to 105C, this device combines Bluetooth 6.0 features, including Angle of Arrival, the new Bluetooth Channel Sounding technology, and BLE Audio. The new Nordic nRF54H20 generates top-end performance across the board, and it is based on a fourth generation radio and an advanced multicore computing architecture.

The module supplies separate M33 Cortex application and radio cores, with shared 1MB RAM and 2MB of non-volatile storage. The Application core can run at 320MHz, allowing complex calculations to be carried out, while the 256MHz radio processor is optimised for fast start-stop to enable low-power radio operation when needed. The high-powered application processor can operate ML models, allowing "AI at the edge".

Also, it contains two RISC-V peripheral processors for high-speed and low-leakage low-speed connections. All processors can run independently. A rich set of peripherals includes High-Speed USB, CAN-FD, High and Low-Speed SPI, UART, I2C, and others. The peripheral processors allow custom device drivers to be added.

Security capability is a significant feature of this device, with ARM Trustzone, secure storage, secure boot and update, and physical and software protection implemented to meet PSA 3 security level (the highest possible for a silicon device of this type).

Despite the advanced features of this device, it is released in a miniature 9mm x 9mm x 1mm package and delivers a fully integrated solution with RF matching and integrated antenna. 32MHz and 32 kHz crystals and DC-DC support for each processor are included, meaning it is a fully functioning Bluetooth node only needing a power supply. With up to +10dBm output power and -100dBm receive sensitivity, coupled with the company's high-performance antenna, this module provides a new level of reliable connectivity.

As well as supporting BLE, the module can run Zigbee, Thread, ANT+ and other 802.15.4 based protocols, concurrently with BLE. Protocol stacks and applications run on the real-time Zephyr operating system, which provides a rich suite of drivers and services. A Matter stack is also available for this device, enabling it to form the core of Smart Home connected devices.

This device complements the ISP2454-LX, which has the same next-generation radio advantages but is targeted at simpler, more cost-sensitive applications.

Nick Wood, sales and marketing director of Insight SIP, said: "The new ISP2554-HM offers a level of capability, performance and security never seen before in such a radio module, allowing customers to build new innovative devices, and replace multiple components with this single device. The miniature footprint and full integration make this RF module 'ready to go' for customers."
