Introduction ISC-nRF54L Module is an Integrated multi-purpose MCU functionality which supports Nordic’s nRF54L Series SoCs which is suited to enable a broad range of applications. The multiprotocol 2.4 GHz radio supports the latest Bluetooth® 6.0 features including Bluetooth Channel Sounding, as well as 802.15.4-2020 for standards such as Thread, Matter, and Zigbee, and a proprietary 2.4 GHz mode supporting up to 4 Mbps for higher throughput. The module integrates the peripherals expected in a wireless microcontroller enabling many products to be implemented with a single chip. 2.
