nRF54LM20A Wireless Chipset by Nordic Semiconductor

The nRF54LM20A 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 more memory, advanced features, and high GPIO counts. This SoC integrates a 128 MHz ARM Cortex-M33 core with a RISC-V co-processor, 2036 KB of NVM, 512 KB of RAM, a multi-protocol 2.4 GHz radio, a 32 MHz crystal, a security block, GPIOs, and serial/peripheral interfaces. It supports protocols such as Bluetooth Low Energy (BLE) 6.0, Thread, Matter, Zigbee, and a proprietary 2.4 GHz mode. This SoC delivers a Tx output power of up to +8 dBm and a data rate of 1/2/4 Mbps (proprietary 2.4 GHz & GFSK).

The nRF54LM20A 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 ARM TrustZone, root of trust, secure boot, key management, and physical protection (e.g. tampler detector). It can be remotely controlled using serial interfaces (I2C, UART, SPI) and EasyDMA/GPIO peripheral interfaces. This SoC requires a DC supply of 1.7 to 3.6 V and consumes 10.1 mA (Tx) & 3.4 mA (Rx) of current. It is available in either a CSP98 package measuring 3.67 x 3.85 mm or a QFN52 package measuring 6.0 x 6.0 mm.
