That means no last-time-buy window to chase, no imminent obsolescence risk for production builds running through 2025 and beyond. For a BOM cost engineer, this is one less single-source flag to carry — the supply channel is stable through franchised distribution and independent stock alike. Dropout margin at the low end is tight — 1.8 V is the absolute minimum, so a battery nearing end-of-life at 1.9 V still keeps the core alive. The internal POR and BOR supervise the rail, so you don't need an external supervisor for brown-out protection. ## 8-channel 10-bit ADC — sensor front-end without an external converter Eight analog inputs with 10-bit resolution cover most low-speed sensor acquisition tasks — thermistors, potentiometers, current shunts, or simple strain-gauge bridges. The ADC shares pins with digital I/O, so a layout engineer can route the analog traces to the dedicated pins and leave the rest for GPIO. No external ADC means one fewer IC to qualify and one fewer decoupling cap on the BOM.","metaTitle":"MSP430F2122IPW 16-bit MCU, 16MHz, 4KB Flash, 28-TSSOP","metaDescription":"Texas Instruments MSP430F2122IPW 16-bit ultra-low-power MCU, 16MHz core, 4KB Flash, 512B RAM, 8x10b ADC, industrial temp -40°C to 85°C, 28-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430F2xx","Package":"Tube","RAM Size":"512 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"24","Core Processor":"MSP430 CPU16","Package / Case":"28-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F2122","Program Memory Size":"4KB (4K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"28-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5d60fb2ef81bef767e2c6d93133979f0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F2122IPW/alternatives.json"},"ai":{"faq":[{"question":"Can MSP430F2122IPW be replaced by MSP430F2132IPW?","answer":"The MSP430F2132IPW is a pin-compatible step-up within the same MSP430F2xx family — it doubles the Flash to 8 KB while keeping the same 28-TSSOP footprint, 16 MHz core, and peripheral set. If your firmware fits in 4 KB, the F2122 is the cost-optimised choice; if you need headroom for additional features, the F2132 is a drop-in swap without a board respin. Both share the same supply range, temperature grade, and ADC."},{"question":"How to program MSP430F2122IPW?","answer":"Programming is done through TI's Spy-Bi-Wire (SBW) two-wire interface, which uses the TEST and RST pins — no dedicated programming header needed beyond those two signals plus Vcc and GND. TI's MSP-FET or any third-party SBW debugger works with Code Composer Studio or IAR Embedded Workbench. The 4 KB Flash is in-system programmable, so firmware updates can be applied on the assembled board without removing the MCU."},{"question":"Is MSP430F2122IPW RoHS compliant?","answer":"Yes, the 'IPW' suffix indicates a RoHS-compliant, lead-free finish on the 28-TSSOP package.
