Insight SiP is launching the ISP2053-AX RF module with a wide range of capabilities including the latest advanced Bluetooth solutions in a tiny package measuring 8 x 8 x 1mm, the smallest package on the market. This high-end device with a dual-core processor supports sophisticated applications and removes the need for an additional host processor.

This module offers the latest technology for advanced Bluetooth solutions with a dual-core ARM processor, BLE 5.2 Long Range connectivity, capability to support BLE Audio, and advanced security features with ARM Trustzone. With extended temperature capability up to 105^oC, this device can support every kind of advanced Bluetooth-based solution including Angle of Arrival and low latency/streaming solutions.

Despite the advanced features of this device, it is released in Insight SiP’s standard 8 x 8 x 1 mm package and offers a fully integrated solution with RF matching and integrated antenna. Both 32MHz and 32 kHz crystals and DC-DC support for each processor are included, meaning it is a fully functioning Bluetooth node only requiring a power supply to operate.

This module is based on the nRF5340 Nordic Semiconductor System on a Chip (SoC). On this next-generation architecture there is a 2.4 GHz transceiver, a 64MHz M33 Network core with 256kB Flash and 64kB RAM, and a 128MHz M33 Application core with 1MB Flash and 512kB RAM. The two cores can be operated independently, offering multiple ways to optimize performance for power consumption, throughput, and real-time response.

A full range of peripheral connections is available to both cores including USB, QSPI, SPI, UART, and others. As well as supporting BLE, the module can run Zigbee, Thread, and other 802.15.4 based protocols, concurrently with BLE. Protocols stacks and applications run on the real-time Zephyr operating system which provides a rich suite of drivers and services.

Security is becoming an increasingly important issue in I0T. The ISP2053 is highly featured in this domain with an ARM Trustzone capability. This allows secure key storage, advanced encryption and root of trust verification, enabling devices to be securely authenticated, updated and data exchange protected end to end.

The ISP2053 RF module is designed to run on a coin cell battery if required. Thanks to the module’s ultra-low power consumption and advanced power management system, the battery can last up to several years.

Initial samples are available now. Full production of the modules will start in 2022. Certification is pending. To help product developers, Insight SiP will offer complete development kits together with sample software that provides everything required out of the box to start developing a solution on day one.
