Battery life of 10 years with a single button cell:
Certified Bluetooth 5.2 modules - BlueGecko BGM220


The BlueGecko BGM220 series from SILICON LABS is compatible with all types of IoT device:

  • 6 x 6 mm compact module for applications with limited space
    BGM220S as an SiP solution
  • RF performance with maximum transmission power of +8 dBm
    BGM220P as a PCB module

Module and SiP solution already certified worldwide

The BGM220 series offers a complete solution based on the EFR32BG22 SoC, including robust software stacks that can be fully updated. Key features of the series include global certification as well as advanced development and debugging tools.

At just 6 × 6 mm, the BGM220S series is the world's smallest Bluetooth SiP solution. An ultra-compact, cost-effective module with minimal power consumption for an extended battery life. 

The BGM220P variant in the series is available in the form of a PCB module.
The BGM220P is optimised for wireless performance. An improved RF link budget enables radio communications over longer distances. 

Battery life of up to 10 years with a single button cell

BGM220S and BGM220P are among the first modules that support positioning via Bluetooth and provide a maximum battery life of ten years with a single button cell.

The BlueGecko BGM220 series offers technology for the fastest growing markets, such as localisation (32% growth rate) together with home automation and networked systems (26% growth rate). These figures are based on a survey by Bluetooth SIG.

Comprehensive security functions provide a safe Bluetooth connection

Security is a key issue for networked applications. SILICON LABS has further improved and developed additional security functions. The following are implemented and executed in the hardware and software:

  • Hardware-accelerated crypto unit
    Faster, more energy-efficient and better security as a pure software solution
  • True Random Number Generator (TRNG)
    Conforms to NIST SP800-90 and AIS-31 authentication of firmware updates
    Prevents the loading of manipulated firmware or a roll-back to previous versions
  • Secure debug with locking/unlocking
    Debug locked for standard devices
    Authenticated access for extended error analysis

Cost-optimised hardware separation of security-related data 


Technical data of PCB modules:

The new PCB modules are available in a PCB package with dimensions of
12.9 x 15.0 x 2.2 mm. The PCB variant offers a higher RF performance than smaller SiP modules. 

  • ARM Cortex M33 with 76.8 MHz
  • +8 dBm transmission power
  • Up to 512 kB flash and 32 kB RAM
  • Bluetooth 5.2


Technical data of SiP modules:

The System-in-Package (SiP) module from SILICON LABS is one of the smallest modules currently available on the market. The modules have extremely compact dimensions of 6.0 x 6.0 x 1.1 mm.

  • ARM Cortex M33 with a clocking frequency of between 38.4 MHz and 76.8 MHz
  • Up to +6 dBm transmission power
  • Up to 512 kB flash and 32 kB RAM
  • Bluetooth 5.2 
  • Temperature range of -40 °C to 105 °C
