BL5340 Series
Multi-Core / Protocol – Bluetooth® + 802.15.4 + NFC Modules
MULTI-CORE & MULTI-PROTOCOL – THE CAPABILITIES ARE ENDLESS
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. Featuring Bluetooth 5.2 including Isochronous Channels and
LE Audio, the BL5340 supports next generation Bluetooth audio for stereo
streaming and broadcast audio.
The 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. This further extends
the multi-protocol capabilities of the product: Bluetooth LE, 802.15.4
(Thread / Zigbee) and NFC. It’s further enhanced with an ARM CryptoCell-
312 including trusted execution, root-of-trust and secure key storage security
features.
The BL5340 series brings out all nRF5340 hardware features and
capabilities including USB access, up to +10dBm certified for PA version
(+3 dBm from SoC) transmit power, from 1.7V to 5.5V supply
considerations, and a true industrial operating range of -40 to 105°C.
Complete regulatory certifications enable faster time to market and reduced
development risk completes Laird Connectivity’s simplification of your next
multi-protocol wireless design!
