Next-generation Bluetooth radio in miniature integrated SiP package launched

Insight SiP launches the ISP2454-MX module in a tiny package measuring 8mm x 8mm x 1mm, the smallest package on the market. With extended temperature capability up to 105C, this device can support next-generation Bluetooth-based solutions, including Angle of Arrival and the new Bluetooth Channel Sounding technology. The latest Nordic nRF54L15 delivers improved performance across the board, based on a fourth-generation radio and a double-speed MPU, compared with the nRF52 series-based devices at a lower cost.

This module can support a wide range of solutions, providing a powerful Arm M33F 128Mhz-based processor and advanced security features with ARM Trustzone. Power consumption is improved in radioactive and sleep modes. Memory capacity is increased with 1.5MB of storage and 256KB RAM, allowing the largest and most sophisticated applications to be run. This improved performance also provides a cost advantage over nRF52-based devices, making it equally suited to price-sensitive products.

Despite its advanced features, this device is released in the company's standard 8mm x 8mm x 1mm package and delivers a fully integrated solution with RF matching and an 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 that only requires a power supply to operate.

A full range of peripheral connections is available, including HS-SPI, SPI, UART, I2S, and others. There is also a software-programmable peripheral independent 128MHz RISC processor that supports alternative high-speed peripherals. In addition to supporting BLE, the module can run Zigbee, Thread, 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.

Nick Wood, sales and marketing director of Insight SiP, said, "The new ISP2454 represents the next generation Bluetooth technology, offering more features and capability at lower cost. A miniature footprint and full integration make this RF module 'ready to go' for customers. It also offers footprint and pin compatibility with nRF52-based modules from Insight SiP, offering an easy upgrade path for customers."

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