BL5340 Series - Multi-Core Bluetooth 5.2 + 802.15.4 + NFC Modules

Under Development

Overview

Laird Connectivity’s newest edition to their Nordic Semiconductor based Bluetooth LE portfolio, is the most advanced, most secure and highest performing dual core MCU architecture wireless solution available. The BL5340 series of robust, tiny modules feature the Nordic nRF5340 SoC. It directly targets the highest performance with the lowest power budget, with variants featuring integrated Nordic nRF21540 PA/LNA for higher TX Power applications.

  • Nordic nRF5340 – 7x7 QFN with 48 GPIOs available.
  • Dual Cortex M33 microcontroller cores
    Application processor - 128/64 MHZ M33 – 1MB Flash/512KB RAM (Including DSP Instructions)
    Network processor - 64 MHz M33 – 256KB Flash/64KB RAM
  • Extended Industrial Temperature Rating (-40° to +105 °C)
  • Module Choice: Main module (BL5340 with nRF5340) or power amplified variant (BL5340PA with nRF5340 + nRF21540)
  • Antenna choice – integrated pre-certified PCB or Trace pad options
  • Small form factor: as small as 15 x 10 x 2.2 mm (BL5340)
  • Development choice: Zephyr RTOS or utilize Nordic nRF Connect SDK
  • Bluetooth LE: Peripheral/Central, 2 Mbps (high throughput), LE Coded (long range), AoA/AoD, LE Audio / Isochronous Channels, Mesh
  • Advanced Security: ARM TrustZone®, Root of Trust, ARM CryptoCell-312 & KMU, Access Control Lists, System Protection Unit, Encrypted QSPI
  • Firmware Over the Air (FOTA) via MCUboot and Zephyr
  • Fully featured development kits to jump start Bluetooth LE development

Become a Part of Our Beta Test Program!

The nRF3540's dual-core Arm® Cortex M33 microcontrollers enable you to run a low power core focused purely on wireless connectivity, with a second higher performance core targeted for the end application itself.

They directly target the highest performance with the lowest power budget, with variants featuring integrated Nordic nRF21540 PA/LNA for higher TX power applications, up to +10dBm transmit power certified for PA version (+3 dBm from SoC).
