The 16 MHz clock is the ceiling for this MSP430 core. At that speed the CPU can execute most single-cycle instructions, but you will need to set the Flash wait state to 1 before raising the clock above 8 MHz, or the core will fault on the first branch. The 4 KB RAM handles a few hundred bytes of buffering and a modest call stack; if your application needs larger data arrays, budget for external SPI SRAM or move up the MSP430F5xxx family. At 3.3 V the internal oscillator is stable within ±1% over temperature after calibration. ## Connectivity and analog — what the I/O and ADC cover With 32 general-purpose I/O pins and a 12-channel 10-bit ADC, this part can handle a dozen analog sensors plus a handful of digital inputs and outputs. The LIN interface is particularly useful for automotive body-electronics slave nodes (window lifts, seat controllers) where the MCU acts as a LIN responder. Note that the ADC is 10-bit, not 12-bit; if you need better than 0.1% resolution on a 3.3 V reference, an external ADC is needed. ## Package and mounting — the 40-VQFN footprint For good thermal performance, stitch vias from the pad to a ground plane on the PCB. ## Lifecycle and sourcing — still active, no EOL worry For dual-sourcing resilience, there is no pin-compatible second source from another vendor, but the MSP430G2xx family includes several Flash-size and RAM variants in the same 40-VQFN footprint that can serve as drop-in upgrades if the firmware fits.","metaTitle":"MSP430G2755IRHA40R 16-bit MCU, 32KB Flash, 16MHz, 40-VQFN","metaDescription":"Texas Instruments MSP430G2755IRHA40R 16-bit MCU with 32KB Flash, 4KB RAM, 16MHz CPU, 12-ch 10-bit ADC, I²C/SPI/UART/LIN, -40°C to 85°C, 40-VQFN.","metaKeywords":null},"attributes":{"series":"MSP430G2xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430G2xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"4K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"32","Core Processor":"MSP430 CPU16","Package / Case":"40-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 12x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2755","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"40-VQFN (6x6)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2800","priceTiers":[{"qty":1,"price":"$4.28000","currency":"USD"},{"qty":10,"price":"$3.84100","currency":"USD"},{"qty":25,"price":"$3.63160","currency":"USD"},{"qty":100,"price":"$3.14730","currency":"USD"},{"qty":250,"price":"$2.98592","currency":"USD"},{"qty":500,"price":"$2.67924","currency":"USD"},{"qty":1000,"price":"$2.25960","currency":"USD"},{"qty":2500,"price":"$2.14662","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d1f4138556eb2f798ba1df7fe827a157.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2755IRHA40R/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for MSP430G2755IRHA40R?","answer":"Within the MSP430G2xx family, parts with the same 40-VQFN footprint and similar Flash/RAM sizes can serve as drop-in upgrades if the firmware is recompiled."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430G2755IRHA40R","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430G2755IRHA40R when reusing this data.
