EFR32BG27 (BG27) - Bluetooth Wireless SoC
EFR32BG27
The BG27 family of Bluetooth LE and Bluetooth mesh SoCs are available with DCDC Boost in WLCSP packaging for small form factor applications, from medical devices to wearables and beyond.
DescriptionSpecificationsNews/ArticlesData Sheet
The EFR32BG27 family of wireless SoCs opens up new possibilities by offering an ultra-small WLCSP package (2.3 mm x 2.6 mm) capable of running on button cell batteries. Now device makers can address applications with extremely small form-factor requirements without sacrificing performance and security. The BG27 Bluetooth SoC features an integrated DCDC boost that allows operation down to 0.8 volts, enabling support for single-cell alkaline and 1.5-volt button cell batteries that are typically used in medical applications for battery-operated patches and continuous glucose monitoring (CGM) devices. Additionally, the wakeup pin on the BG27 allows products in a warehouse or transit to remain off for months, consuming less than 20 nA, ensuring the battery remains fully charged for use. The integrated coulomb counter enables accurate battery level monitoring to avoid unexpected battery depletion for critical applications.
