On-chip peripherals cover brown-out detect/reset, PWM outputs, and a watchdog timer. The device operates from a 2.2 V to 3.6 V supply and is rated over the -40°C to 105°C industrial temperature range, making it suitable for outdoor cabinet and engine-bay environments where thermal cycling is a factor. The four 24-bit sigma-delta converters are the headline feature of this part. For a three-phase meter, the four channels cover three voltage and one neutral current input, or three current and one voltage input, depending on the topology. The 24-bit resolution provides the dynamic range needed to measure both standby power (milliamps) and full-load current through the same shunt or current transformer, without gain switching. The MSP430I2041TPWR carries an EOL hot lifecycle flag, indicating that Texas Instruments has initiated end-of-life planning for this device. Buyers should verify the last-time-buy schedule and consider qualifying a replacement before the final order window closes. Supplied in a 28-pin TSSOP package (0.173\" body width, 4.40 mm) for surface-mount assembly. The supplier device package is 28-TSSOP. The tape-and-reel variant (TR suffix) is suited for automated pick-and-place; cut-tape (CT) is available for prototyping or low-volume builds. The 12 I/O pins plus the four ADC inputs share the 28-pin count, so pin allocation should be reviewed against the target application's sensor interface and communication needs before layout.","metaTitle":"TI MSP430I2041TPWR 16-bit MCU, 16.384 MHz, 32 KB Flash, 28-TSSOP","metaDescription":"Texas Instruments MSP430I2041TPWR 16-bit MCU with 16.384 MHz CPU, 32 KB Flash, 2K x 8 RAM, 4x24-bit sigma-delta ADC, -40 to 105°C.
