nRF54LM20B Wireless Chipset by Nordic Semiconductor
The nRF54LM20B from Nordic Semiconductor is a Multiprotocol Wireless System-on-Chip (SoC). It is designed for demanding designs in Bluetooth devices used in smart homes and industrial applications that require very high memory and other advanced features. This SoC integrates a 128 MHz ARM Cortex-M33 core with a RISC-V co-processor and a 128 MHz Axon NPU for edge AI computing. It also includes 2 MB of NVM and 512 KB of RAM memories, a multi-protocol 2.4 GHz radio, a 32 MHz crystal, a security block, and serial/peripheral interfaces. This wireless SoC supports protocols such as Bluetooth Low Energy (BLE) 6.0, Thread, Matter, Zigbee, and a proprietary 2.4 GHz mode. It delivers a Tx output power of up to +8 dBm and has an Rx sensitivity of -101 dBm.
The nRF54LM20B adopts several features from Bluetooth LE – LE 2M, LE 1M, LE-coded and channel sounding for accurate range measurement. This wireless SoC is equipped with multiple security functions, including TrustZone isolation, a cryptographic engine with side-channel leakage protection, and physical protection (e.g. tampler detection). It can be remotely controlled using multiple interfaces such as I2C, UART, ADC, USB, and GPIO. This SoC requires a DC supply of 3 V and consumes 4.8 mA (Tx) & 3.4 mA (Rx) of current. It is available in either a CSP package measuring 3.85 x 3.67 mm or a QFN package that measures 6 x 6 mm.
