How does a cost-effective wireless MCU help you implement low-power Bluetooth technology into more products

May 31 , 2023 0

Looking at the applications of Bluetooth in our daily lives today, it's reasonable to expect a world of greater connectivity in the future. The Bluetooth Technology Alliance (SIG) estimates that annual shipments of Bluetooth devices will exceed 7 billion by 2026. In medical devices, toys, personal electronics, smart home devices and other areas, the market needs higher Bluetooth integration. To meet this market demand, there will be opportunities for innovative engineers.

Bluetooth in the medical field

Bluetooth features are increasingly being used in medical applications, including blood sugar monitors, medical sensor patches and even smart toothbrushes. For designers, it is necessary to meet consumer demand for the following features:

Small in size and easy to use. No one wants to have a lot of restrictions when using a glucose monitor or a temperature patch.

Long battery life. Longer battery life helps give consumers the peace of mind to use some devices in an emergency.

Powerful performance. Providing a reliable connection is critical.

The development trend of Bluetooth in personal electronics

While personal electronics such as gaming products, toys, or remote controls are very different from medical life-saving devices, the features required to integrate Bluetooth are more similar, including:

Stylish and practical design. Whether it's a wireless keyboard or a mouse, consumers prefer trendy products.

Longer battery life. A single charge can maintain stable operation.

Low cost. The products offered are good in quality and cheap in price.

To help you meet the requirements of the above trends

Until now, engineers have had to make trade-offs when implementing Bluetooth technology, such as sacrificing RF performance and quality due to cost constraints.

TI's SimpleLinkTM product line, which includes the CC2340 Wireless Microcontroller (MCU), helps address design challenges encountered in medical and personal electronics applications:

Up to 512KB of flash memory and 36KB of RAM allow for flexible configuration and extended feature support.

The compact form factor (4mm x 4mm or 5mm x 5mm package) and integrated balanced and non-balanced transformers facilitate the design of space-constrained applications.

The MCU's low power reset/shutdown current is less than 150nA and standby current is less than 830nA, which can extend the battery life to a greater extent.

Helps designers deploy high-quality Bluetooth to more low-cost products.

In addition to the examples presented in this article, TI designs Bluetooth Low power wireless MCUS to meet the evolving needs of many other industries such as building automation, lighting and retail automation.

Available in a variety of features and price points, the CC2340 series is suitable for a wide range of low-power Bluetooth applications, helping you create a more connected world.
