module collects and transmits electrocardiogram data

Dedicated to providing ‘chiplet’ chip-scale solutions to the AIoT market, Bravechip has launched a miniaturized module designed for use in medical devices that supports electrocardiogram (ECG) readings. With a form factor of just 9 by 9 mm, the ‘BCL601S1 Bluetooth ECG Chiplet’ offers motion state detection, as well as heart rate and heart rate variability (HRV) calculations. It can be used in a variety of Bluetooth® LE ECG product designs, such as dynamic ECG recorders, ECG patches, ECG watches, and ECG suits.

Powerful processing capability

The BCL601S1 is powered by Nordic Semiconductor’s nRF52840 SoC, and includes an ECG Analog Front-End (AFE), a G-sensor for collecting motion status, as well as 1 GB Flash memory for raw ECG data. Once this data has been collected it can either be downloaded from the device via USB, or using the Bluetooth LE connectivity of the Nordic SoC.

Low power benefits

“The low power consumption of the chip was also a major drawcard. The BCL601S1 module can be powered either by rechargeable lithium batteries or coin cell batteries, and can achieve a power consumption of less than 0.5 mA in acquisition, transmission, and storage modes.”
