Called ISP2454-MX, it is based on Nordic Semiconductor’s nRF54L15, which can also handle Bluetooth Mesh, Thread, Matter, other 802.15.4 protocols (Zigbee) and ANT communication alongside Bluetooth.
Output power is +8dBm and receiver sensitivity is -98dBm.
“It is a fully-functioning Bluetooth node only requiring a power supply to operate,” according to Insight. “With its 128MHz Cortex-M33 processor, expanded memory and new set of peripherals, it is a direct upgrade to the ISP1507, ISP1807 and ISP1907 series with pin-to-pin compatibility.”
1.5Mbyte of storage and 256kbyte of ram has been included, and the Cortex-M33 has Arm’s Trustzone hardware security – PSA level 3 certification is expected.
Zigbee, Thread and other 802.15.4 based protocols can run concurrently with Bluetooth LE, with protocols stacks and applications on the real-time operating system (Zephyr) which provides drivers and services.
Operation is possible over 1.7 to 2.6V and -40 to 105°C.
It can run from a coin cell battery – “thanks to the ultra-low power consumption, the battery can last up to several years,” it said.
HS-SPI, SPI, UART, I2S and 32 GPIOs are among the module’s interfaces, and both 32MHz and 32kHz crystals are built-in.
Samples are available now, with production scheduled for early 2025. Certification is pending, as are development kits and sample software.
