The 24 I/O pins and integrated peripherals (brown-out detect, POR, PWM, WDT, plus I²C, SPI, UART, IrDA, and LINbus) let it replace a handful of discrete supervisor and interface ICs in a compact 32-VQFN package. ## 4 KB Flash and 512 B RAM — sizing the firmware envelope At 4 KB of Flash, the firmware image is tight. There is no room for a dual-bank OTA scheme or a large lookup table — the code must be lean, typically a state machine with a few hundred lines of C. The 512 B RAM handles a modest stack, a couple of buffers, and the register file. If the application needs over-the-air updates or a complex protocol stack, this part is not the fit; step up to the 8 KB or 16 KB MSP430 siblings in the same family. At the low end, the MCU can run directly from a near-depleted cell, which matters for battery-powered sensors and portable instruments. ## Peripheral integration — what the on-chip blocks save on the BOM The brown-out detect and POR eliminate an external supervisor IC in many designs. The PWM module drives small loads or feeds an external gate driver. The 8-channel 10-bit ADC samples analog sensors without an external converter. The I²C, SPI, UART, and LINbus interfaces handle most common serial buses — LINbus is especially useful for automotive body-node communication. IrDA is a niche but present for legacy infrared links. The 24 I/O pins are enough for a keypad matrix, a small LCD segment driver, or a handful of discrete sensor inputs.","metaTitle":"TI MSP430F2122IRHBR 16-Bit MCU, 16 MHz, 4 KB Flash, 32-VQFN","metaDescription":"Texas Instruments MSP430F2122IRHBR 16-bit MCU, 16 MHz core, 4 KB Flash, 512 B RAM, 24 I/O, I²C/SPI/UART/LIN, 1.8–3.6 V, -40 to 85°C, 32-VQFN.","metaKeywords":null},"attributes":{"series":"MSP430F2xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430F2xx","Package":"Tape & Reel (TR) Cut Tape (CT)","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":"32-VFQFN Exposed Pad","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":"32-VQFN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3400","priceTiers":[{"qty":1,"price":"$4.34000","currency":"USD"},{"qty":10,"price":"$3.89400","currency":"USD"},{"qty":25,"price":"$3.68160","currency":"USD"},{"qty":100,"price":"$3.19060","currency":"USD"},{"qty":250,"price":"$3.02696","currency":"USD"},{"qty":500,"price":"$2.71610","currency":"USD"},{"qty":1000,"price":"$2.29068","currency":"USD"},{"qty":3000,"price":"$2.17615","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5d60fb2ef81bef767e2c6d93133979f0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F2122IRHBR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430F2122IRHBR RoHS compliant?","answer":"Yes, it is ROHS3 Compliant per the lifecycle record."},{"question":"Can MSP430F2122IRHBR replace MSP430F2122IRHBT?","answer":"The order codes differ only in the packaging suffix — IRHBR (Tape & Reel) versus IRHBT (Cut Tape).

The replacement depends on whether your assembly line is set up for reel-fed pick-and-place (IRHBR) or tube/tray handling (IRHBT)."},{"question":"What is the closest functional second-source for MSP430F2122IRHBR?","answer":"The TI C2000 F280041PZQR is a 32-bit C28x MCU with a 100 MHz core, 21-channel 12-bit ADC, and CANbus — it is not a pin-compatible or code-compatible replacement. The MSP430F2xx series itself has larger Flash and RAM variants (e.g., MSP430F2132 with 8 KB Flash) that share the same core and peripheral set, but they are TI's own siblings, not independent second sources."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F2122IRHBR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F2122IRHBR when reusing this data.
