BG27 Bluetooth SoC helps CGM devices last up to 21 days

In today's medical field, continuous glucose monitoring ( CGM ) has become the focus of attention, especially for diabetic patients, real-time understanding of blood glucose level changes is of great significance for treatment and quality of life. With the continuous development of wearable technology, various types of blood glucose monitoring devices have emerged. Among them, the application of the extremely small and ultra-low power EFR32BG27 ( BG27 ) Bluetooth SoC provided by Silicon Labs in CGM is particularly prominent.

BG27 is based on the ARM Cortex-M33 processor core, with advantages such as ultra-low power consumption, ultra-small size and ultra-large resources, making it an ideal choice for CGM devices. This article will introduce in detail the application of BG27 Bluetooth SoC in CGM and its outstanding features.

Ultra-low power consumption greatly extends the use time of the device

In CGM devices, long-term blood glucose monitoring is a key requirement. As its central processor, the low power consumption performance of the chip will directly affect the battery life of the device. The current CGM on the market can be used for about 14 days, and the BG27 Bluetooth SoC has leading low-power technology, which can achieve an ultra-long battery life of 21 days. Its power consumption in Active mode is only 29 μA/MHz in Active Mode (EM0) at 76.8 MHz , while it is 1.6 μA in Deep Sleep mode and only 0.18 μA in wake-up mode . This ultra-low power consumption performance can ensure that the CGM device can greatly extend the use time of the device while continuously monitoring.

Ultra-small size, the CGM device can be made the size of a coin

With the change of traditional lifestyle, consumers have higher requirements for the size and lightness of medical equipment. BG27 Bluetooth SoC adopts WLCSP39 package, with a size of only 2.291 mm × 2.624 mm × 0.5 mm, 0.35 mm , which can greatly reduce the size of CGM and make the CGM instrument as small as a coin;

Sufficient computing power and hardware resources to process complex numerical data

As the control core of smart CGM devices, the chip needs to have ultra-low power consumption and ultra-small size, as well as sufficient computing power and hardware resources to process complex numerical data. The BG27 Bluetooth SoC has built-in 768 kB flash , 64 kB RAM and a high-performance hardware encryption engine, which can easily handle tasks such as real-time collection, storage and encrypted transmission of blood glucose data.

Convenient software platform for rapid development of high-performance products

Silicon Labs provides a complete software development platform and API interface for the BG27 Bluetooth SoC , allowing developers to easily develop products according to their needs and create high-performance CGM devices.

In summary, Silicon Labs' BG27 Bluetooth SoC occupies an important position in the CGM field with its advantages of ultra-low power consumption, ultra-small size, and ultra-large resources . With the increase in the number of diabetic patients and the continuous upgrading of medical needs, BG27 Bluetooth SoC will play an increasingly important role in the fields of wearable devices such as sports health and medical health.
