World’s Smallest Bluetooth Chip Is Only 5mm2


Here’s the tiniest Bluetooth chip measuring just 5mm2 ideal for adding Bluetooth communication to any portable electronic device. Not only it is the smallest chip available, it also claims the lowest energy consumption helping to increase the autonomy of connected objects. It is also faster than the competition, which can improve the speed of the devices it is installed in.

Consisting of more than 5 million transistors on a surface of about 5 mm2, the EM9304 is optimised for Bluetooth v5.0 low energy enabled products such as portable electronic devices and for the Internet of Things.

The chip designed by Swatch Group supports Bluetooth low energy applications such as: Beacons, Wearables and Sports Equipment, Healthcare Monitoring, Remote Sensing, Motion and Tracking Devices, Home Automation, Light Control Applications, Wireless Mice and Keyboards, Toys, and Alarms and Security Systems.

The flexible architecture of the EM9304 allows it to act as a companion IC to any ASIC or MCU-based product, or as a complete System-on-Chip (SoC).


“The ultra-miniaturization of electronic components is crucial for the densification of functions in portable electronic devices and for the Internet of Things,” the firm said.

“The chip can work alone or in conjunction with various sensors; system integrators can take advantage of a microcontroller with very low power consumption or can use the chip to add a Bluetooth communication function to any portable electronic device,” Swatch added.

The device is offered in a WLCSP-21 wafer level chip-scale package, a plastic QFN-28 package, and bare die/ wafer form. The device and reference design is qualified over the industrial temperature range.

Customer support for PCB design, and FCC/CE certification are available. A hardware and software development kit are available, including commercially available tools with IDE and debugger.  A website and forum are also available to help for custom developments.
