New BG22L delivers robust security and
processing for common Bluetooth devices, while BG24L supports
advanced AI/ML acceleration and Channel Sounding
AUSTIN,
Texas, Jan. 30, 2025 /PRNewswire/ -- Silicon
Labs (NASDAQ: SLAB), a leader in secure, intelligent wireless
technology for a more connected world, introduced the BG22L and
BG24L SoCs for Bluetooth® LE connectivity, with "L"
representing the new application-optimized Lite devices.
Optimized for common Bluetooth applications like asset tracking
tags and small appliances, the BG22L brings the most competitive
combination of security, processing power, and connectivity for
high-volume, cost-sensitive, and low-power applications. The BG24L
SoC includes the Silicon Labs accelerator for AI/ML applications
and support for Bluetooth Channel Sounding for asset tracking and
geofencing, even in the most crowded areas like packed warehouses
and multi-family housing units.
"We know that our customers are always looking for ways to keep
pace with the demands of the evolving IoT market while reducing
costs," said Ross Sabolcik, senior
vice president of the Industrial and Commercial business unit at
Silicon Labs. "The BG22L and BG24L expand our portfolio to match
those customer needs and concerns by providing an optimized set of
industry-leading Bluetooth features with our signature IoT
capabilities like high RF sensitivity, low power, robust security,
and powerful compute."
BG24L Accelerates Adoption of Bluetooth® 6.0 and
Channel Sounding
Channel Sounding was one of the most exciting features when the
Bluetooth SIG announced Bluetooth® 6.0 in September 2024. It allows Bluetooth 6.0 devices
like the BG24L SoC to use two-way connections to determine the
distance between themselves within sub-meter accuracy. This opens a
range of applications from item finding to access control. For
example, users would be able to locate keys, wallets, or any other
Bluetooth 6.0-equipped item at a fraction of the power of other
ranging technologies. In commercial and industrial environments,
Channel Sounding brings similar item-finding functionality to
retail shelves, distribution centers, and more.
Another use case for channel sounding is wireless access
control. Bluetooth 6.0-equipped devices will be able to communicate
with vehicles, package lockers, and other things that generally
require an interaction or passcode. By sensing that a device is in
close proximity, the locker or vehicle can open automatically
simply by recognizing the signal of the approaching, securely
designated Bluetooth device.
With a 78 MHz ARM Cortex M33 processor, 768 kB of Flash, and 96
kB of RAM in a 5 mm x 5 mm QFN40 packaging, the BG24L is a
cost-effective SoC for high-volume Bluetooth Channel Sounding.

the Bluetooth Channel Sounding application using a similar SoC.
For AI and machine learning applications, the BG24L also
includes Silicon Labs' proprietary Matrix Vector Processor (MVP)
AI/ML accelerator. With the embedded MVP accelerator, the BG24L
provides up to 8x faster inferencing performance using only
1/6th of the power compared to performing the same
calculations on the Cortex M, thereby extending battery life. This
makes BG24L an ideal ML inferencing platform for time-series data
on IoT applications such as sensors and predictive maintenance.
Using AI/ML development tools from Silicon Labs and its partners,
BG24L is the easiest and most accessible IoT platform for exploring
the possibilities of edge AI.
BG22L Offers Up to Ten Years of Battery Life on a Coin Cell
Battery
Advancements like Channel Sounding and AI/ML are pushing the
boundaries of what's possible with Bluetooth applications. However,
there are still opportunities to leverage the core strengths of
Bluetooth, with billions of devices using it for simple sensors,
asset tracking, beacons, and streamlined Wi-Fi setup for
appliances.
The BG22L is competitively designed for these common wireless
applications where robust, secure Bluetooth connectivity is needed.
BG22L SoCs deliver an exceptional balance of low cost, low power
consumption, high reliability, and superior performance. It
includes ultra-low power receive mode along with a Precision
Low-Frequency RC Oscillator (PLFRCO) that eliminates the need for
an external oscillator with no performance loss, which conserves
space within the host device while saving on costs and bills of
materials for the manufacturer. These enhancements enable BG22L to
operate for up to ten years on a single coin cell battery.
The BG22L also supports Bluetooth 5.4 and Bluetooth Direction
Finding. It features an ARM Cortex M33 processor at 38.4 MHz, up to
352 kB of flash, and up to 24 kB of RAM in a 4 mm x 4 mm QFN32
packaging.
