The core runs at 16.384 MHz, a deliberate clock speed chosen to match power-line cycle rejection (50/60 Hz) without extra filtering. Program memory is 32 KB of Flash, with 2 KB of RAM for data and calibration coefficients. The three 24-bit sigma-delta converters let this single chip handle simultaneous voltage, current, and temperature sensing in a power meter or a weigh-scale bridge. That integration removes an external ADC and its reference, saving board area and reducing the analog routing headache. The 16.384 MHz clock is not arbitrary — it lets the ADC decimation filter notch out 50 Hz and 60 Hz line noise cleanly, which is why this part shows up in energy-monitoring and industrial sensor designs. If your application does not need that measurement precision, a general-purpose MSP430G series part with fewer ADC bits and a lower price point might be a better fit. ## 28-TSSOP — footprint and field-swap reality No hidden thermal pad, no exposed die — just a straightforward SOIC-like body. If you are swapping this on site without a hot-air station, a fine-tip iron and flux wick will get the old one off and the new one aligned. The pin 1 indicator is molded into the package, so orientation is unambiguous even under a magnifying lamp.","metaTitle":"TI MSP430I2031TPW 16-Bit MCU, 16.384 MHz, 32 KB Flash","metaDescription":"Texas Instruments MSP430I2031TPW 16-bit MCU with 16.384 MHz CPU, 32 KB Flash, 2 KB RAM, and three 24-bit sigma-delta ADCs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"12","Core Processor":"MSP430 CPU16","Package / Case":"28-TSSOP (0.173\\\", 4.40mm Width)","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":"28-TSSOP","Voltage - Supply (Vcc/Vdd)":"2.2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4702","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/930bb8693ea1d814311da91a1434267f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430I2031TPW/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430I2031TPW in this component family?","answer":"Within the MSP430I2xx series, parts with the same 28-TSSOP package and similar ADC count share the pinout.
