Modern handheld medical devices require a sensor interface, precision conversion circuit, flash MCU, user display, communication features and a power supply. In the past, to meet the conflicting electronics requirements of low power and high precision, handcrafted application specific integrated circuit (ASIC) solutions were used. Designers today are moving toward using off-the-shelf, ultra-low power, mixed-signal controllers with embedded analog to meet the power, precision, fast time-to-market and cost requirements.

TI´s ultra-low-power MCU family, the MSP430, is featured on the following personal medical device applications
