Electroencephalogram

The TGAM Processor is a cutting-edge device engineered to meet the demanding requirements of electroencephalography (EEG) systems, offering a comprehensive suite of features meticulously designed to ensure optimal performance and reliability. With a robust memory capacity of 16KB Flash and 1KB EEPROM, this processor facilitates efficient storage and retrieval of critical data, enabling seamless operation in both real-time monitoring and data logging applications. Security is paramount, with integrated Power On Reset (POR) and Brown Out Detection (BOD) mechanisms providing safeguards against unexpected power fluctuations, while ESD protection up to 8kV ensures resilience against electrostatic discharge events, enhancing overall device longevity and durability.

At the core of its functionality lies a high-performance sampling system capable of achieving a sampling frequency of 512 bits per second across a broad frequency range of 3-100Hz. This enables precise and accurate capture of brainwave signals, crucial for detailed analysis and interpretation in clinical and research settings alike. Furthermore, the TGAM Processor offers flexible UART output baud rates ranging from 1200 to 57600, catering to diverse communication protocols and facilitating seamless integration with external systems and devices.

One of the standout features of the TGAM Processor is its direct compatibility with dry electrodes, eliminating the need for cumbersome and time-consuming preparation associated with traditional wet sensors. This streamlined approach not only simplifies electrode placement but also enhances user comfort and convenience, making the device suitable for a wide range of applications and user demographics. Additionally, an adjustable AC noise filter, configurable for both 50Hz and 60Hz frequencies, ensures optimal signal clarity, mitigating potential interference and artifacts that could compromise data accuracy and reliability.

In terms of data processing capabilities, the TGAM Processor excels in a multitude of tasks essential for EEG analysis. From measuring raw brainwave signals to processing EEG power spectra and conducting EEG/ECG signal quality analysis, this versatile device empowers users with comprehensive insights into brain activity and function. Moreover, built-in eye blink detection functionality adds another layer of sophistication, enabling researchers and clinicians to identify and analyze specific neural phenomena with precision and accuracy.

Despite its advanced capabilities, the TGAM Processor remains remarkably power-efficient, with a maximum consumption of 15mA at 3.3V. This ensures prolonged operation on battery-powered systems without sacrificing performance or compromising user experience. Pinout configurations for Electrode (p1), Power (p4), and UART/Serial (p3) headers are meticulously documented, providing clear and concise guidelines for seamless integration into EEG systems, further enhancing usability and versatility.
