It is designed for energy monitoring, flow metering, and industrial sensor applications where you need to digitise low-level analog signals directly, without an external AFE. ## Three 24-bit sigma-delta ADCs — what the rating means for the BOM The three 24-bit sigma-delta converters are the headline feature. They let the MCU sample voltage and current channels simultaneously — think single-phase energy metering with anti-aliasing handled in the digital domain. The 16.384 MHz clock is not arbitrary; it is a multiple of 50/60 Hz line frequencies, so you can synchronise sampling to the mains cycle without an external PLL. That integration removes an external ADC and its reference from the BOM, which is the whole point of this device class. ## Industrial temperature range and connectivity set The peripheral set includes a brown-out detect/reset, PWM outputs, and a watchdog timer. For interfaces you get I2C, SPI, UART/USART, plus IrDA and SCI — enough to talk to an external display, a radio module, or a host controller. Sixteen GPIOs in the 32-VQFN package give you room for a few local sensors and a status LED. TI lists this part as Active. That means it is still in standard production flow — no last-time-buy window, no NRND flag. The base product number is MSP430I2031, so if you need a different package or temperature grade later, that is the root to search. ## Sourcing posture for this part Because it is an active TI part, the franchised channel also carries it, but if you are filling a short-notice BOM gap or need a specific date-code range, the independent route gives you faster access to real inventory without waiting for a factory lead-time cycle.","metaTitle":"TI MSP430I2031TRHBT 16-bit MCU, 16.384 MHz, 32KB Flash","metaDescription":"Texas Instruments MSP430I2031TRHBT 16-bit MCU with 16.384 MHz CPU, 32KB Flash, 2K x 8 RAM, three 24-bit sigma-delta ADCs.","metaKeywords":null},"attributes":{"series":"MSP430I2xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16.384Mhz","Series":"MSP430I2xx","Package":"Tube","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, PWM, WDT","Connectivity":"I2C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"16","Core Processor":"MSP430 CPU16","Package / Case":"32-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 3x24b Sigma-Delta","Oscillator Type":"External","lifecycle_stage":"eol_hot","Base Product Number":"MSP430I2031","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"32-VQFN (5x5)","Voltage - Supply (Vcc/Vdd)":"2.2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9700","priceTiers":[{"qty":1,"price":"$3.97000","currency":"USD"},{"qty":10,"price":"$3.56500","currency":"USD"},{"qty":25,"price":"$3.37000","currency":"USD"},{"qty":100,"price":"$2.92080","currency":"USD"},{"qty":250,"price":"$2.77100","currency":"USD"},{"qty":500,"price":"$2.48640","currency":"USD"},{"qty":1000,"price":"$2.09696","currency":"USD"},{"qty":2500,"price":"$1.99211","currency":"USD"},{"qty":5000,"price":"$1.91722","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/930bb8693ea1d814311da91a1434267f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430I2031TRHBT/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430I2031TRHBT active or obsolete?","answer":"Texas Instruments lists the MSP430I2031TRHBT as Active.
