MSP430F149IPMR – TEXAS INSTRUMENTS

The Texas Instruments MSP430F149IPMR is a low-power, 16-bit mixed-signal microcontroller based on the ultra-low-power MSP430 architecture. It features a 16-bit RISC CPU, 16KB of Flash program memory, and 1KB of RAM. Crucially, it integrates a 10-bit ADC with 8 channels, a versatile USART, and a low-power watchdog timer, all critical for battery-powered applications. Operating from a 1.8V to 3.6V supply voltage range, the device boasts exceptionally low active and standby current consumption, making it ideal for energy-harvesting and long-life battery systems._x000D_

Packaged in a space-saving 20-pin TSSOP (thin shrink small outline package), the MSP430F149IPMR is well-suited for compact designs. Its primary advantages stem from its extremely low power consumption and integrated peripherals. Common use cases include portable medical devices, remote sensors, wearable electronics, and other applications demanding extended battery life without compromising functionality. The integrated ADC allows for direct analog signal acquisition, simplifying circuit design and reducing component count. Its low-power characteristics minimize the need for complex power management circuitry, contributing to overall system efficiency and cost-effectiveness.
