SPAIN, Barcelona – February 22, 2016 – As the global demand for mobile health devices continues to grow, MediaTek today announced the MT2511, MediaTek’s first bio-sensing analog front-end (AFE) chip designed for health and fitness devices. The MT2511 enables bio signal acquisition through electrocardiography (ECG) and photoplethysmography (PPG) simultaneously.

MT2511 is extremely power efficient, providing a lower active mode power consumption of less than 0.6mA while capturing PPG. In addition, MT2511 is equipped with MediaTek’s exclusive built-in heart beat interval technology and 4KB SRAM to optimize overall system power consumption for sleep heart rate monitoring. Finally, MT2511 also integrates LED boost driver circuit for saving layout space.

“The mobile health market is one of the fastest growing technology sectors. We can only begin to imagine how health-related wearables will improve both medical care and everyday wellness all around the world,” said JC Hsu, MediaTek’s Corporate Vice President and General Manager of the IoT business unit. “With support for ECG and PPG and limited power needs, the fully integrated MT2511 is ideal for a variety of devices, including fitness trackers, active lifestyle smart watches and sports bands.”

With its support for a greater than 100db dynamic range and high sample rate from 64 to 4KHz, the MT2511 eliminates interference and motion artifacts when collecting the heart’s electric signals. Because the MT2511 gathers accurate pulse data, it enables a variety of applications including electromyography (EMG), electroencephalography (EEG), pulse oximetry (SpO2) and blood pressure.

The flexible design of the MT2511 means it works seamlessly with MediaTek’s existing IoT and wearables platforms, including the MT2502, MT2523, and MT2601 for Android Wear, allowing device manufacturers to cater to a variety of needs. Advantages of the design range from simple to rich applications, with or without touch screens, or paired with a SoC or microcontroller unit (MCU).

The MediaTek MT2511 is expected to begin mass production in the first half of 2016. At Mobile World Congress 2016, MediaTek will show the MT2511 and the hardware development kit that combines it with MediaTek’s MT2523 platform. Together, this will demonstrate a complete system-in-package (SiP) for wearables with GPS, dual-mode Bluetooth LE, support for high-resolution screens and a highly-efficient Cortex M4 CPU.
