BG2B is the lowest-power Bluetooth LE SoC from Silicon Labs so far

Silicon Labs BG2B

Silicon Labs BG2B is an ultra-low-power Arm Cortex-M33 Bluetooth 6 LE SoC with support for Channel Sounding, “Secure Vault High” security, and integrated CAN-FD and peripherals such as LED drivers and ADCs for smaller, longer-lasting IoT devices. The company claims it’s the lowest-power Bluetooth LE device in its portfolio, with 1.1 µA EM2 sleep current with RAM retention, as well as 14%-15% lower MCU active current and lower Bluetooth receive current compared to Silicon Labs BG22/BG22L. The new microcontroller targets secure ranging, asset tracking, electronic shelf labels (ESLs), smart home, industrial monitoring, and vehicle diagnostics. Silicon Labs BG2B specifications: CPU core – 32-bit Arm Cortex-M33 @ 80 MHz with DSP instructions and floating-point unit (FPU) Memory – 64 kB or 128 kB SRAM Storage – 1016 kB flash Wireless – 2.4 GHz radio Modulation Formats OQPSK DSSS 2 (G)FSK with fully configurable shaping (G)MSK Protocols Bluetooth Low Energy 6 Channel […]

nRF54L Arduino Core project brings Arduino support to Nordic Semi nRF54L wireless SoCs

nRF54L Arduino Core

nRF54L Arduino Core is an open-source project designed to bring Arduino support for Nordic Semiconductor nRF54L wireless SoCs, starting with Seeed Studio’s XIAO nRF54L15 (Sense) and XIAO nRF54LM20A (Sense) boards, as well as compatible Holyiot nRF54L15 modules. Since the launch of the nRF52840-based Arduino Nano 33 BLE  board in 2019, Nordic nRF52 wireless microcontrollers have been officially supported by the Arduino IDE. However, it’s not quite the case for the newer nRF54L Cortex-M33 microcontrollers. Lolren has decided to change that with the unofficial nRF54 Arduino core project. nRF54L Arduino Core highlights: Dual-core access – Use the 128 MHz Cortex-M33 application CPU and the VPR RISC-V coprocessor without adopting a vendor RTOS Wireless Bluetooth LE support – Peripheral, central, dual-role, GATT server/client, HID, BLE UART, PHY/DLE/MTU control, LE Secure Connections, bonding, OOB, Numeric Comparison, privacy/RPA, and CSRK signed writes Experimental support for Zigbee – Partial stack and device demonstrations; incomplete Zigbee […]
