Texas Instruments Inc. (TI)'s MSP430F149 ultra-low power microcontroller (MCU) and analog technologies are key elements for Recom Managed Systems Inc. battery powered high-fidelity biomedical signal processing and recording platform.

Recom's first product based on this platform, the Model 100, is an ambulatory patient heart monitor that uses patented signal processing technology to record a clinical quality electrocardiograph (ECG) signal in the presence of noise generated by the patient's body movements and ambient environment.

Recom's Model 100 is a portable embedded system that requires absolute lowest power and maximum reliability. TI's MSP430F149 MCU handles the Model 100's data acquisition and pre-processing. The MSP430F149 integrates a 16bit RISC CPU, 16bit registers, constant generators for maximum code efficiency and a 12bit analog-to-digital converter (ADC). The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6 us. The device's core and peripherals, which are optimized for ultra-low power, extend battery life, keeps the Recom Model 100 ECG operating over a longer period of time and makes it a more cost-effective solution.
