Medical ECG Slide 31

For readers that have not heard about or used the MSP430 before, it is a low power 16-bit RISC architecture based MCU. The MSP430 has popular appeal in the portable system on-chip, battery powered, consumer medical space. This includes items such as athletic equipment with heart rate monitors, hand held ECG displays and so on. The MSP430 family, which is well suited for ECG and heart rate applications is the FG46x family, shown in the block diagram on this slide. This family includes the FG43x, the FG47x, and the FG461x devices. What the MSP430 is primarily known for is low power operation. With sub-1 µA standby currents or 300 µA active current, the MSP430 is an ideal choice if one has a battery powered application. The MSP430 also typically comes with highly integrated analog op-amps, with a 12-bit ADC, and 16-bit or 12-bit DACs. TI provides a system-on-chip solution which means less external components for the user’s design. The MSP430 also has a diverse portfolio, which means there is a broad range of flash memory, peripherals, and the customer can select an MCU that fits their application needs.
