The 56 KB Flash is enough for moderate firmware stacks — sensor fusion, motor-control loops, or a Modbus node — without forcing code compression or external memory. For a BOM line, this part replaces a lower-density MSP430G2xx when the firmware outgrows 32 KB, and it keeps the same peripheral set and pinout across the family. ## Built-in ADC and serial interfaces Twelve 10-bit ADC channels are on-chip, covering most analog sensor inputs without an external converter. ## Package and rework — 40-VQFN with exposed pad The 40-VQFN (6x6 mm) package has an exposed thermal pad underneath. The pad also anchors the part during reflow; a hot-air station can lift it cleanly if the board is preheated to 100°C. Not rated for under-hood (125°C) environments, so keep it out of the engine bay. ## Lifecycle — active, no obsolescence concern TI lists the MSP430G2955IRHA40R as Active. That means no end-of-life notice pending, no last-time-buy scramble.","metaTitle":"MSP430G2955IRHA40R Texas Instruments MCU, 16-bit, 56KB Flash","metaDescription":"Texas Instruments MSP430G2955IRHA40R 16-bit MCU with 56KB Flash, 16MHz, 4K x 8 RAM, 12-channel 10-bit ADC, I²C/SPI/UART, -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":"MSP430G2955","Program Memory Size":"56KB (56K 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":"$4.6700","priceTiers":[{"qty":1,"price":"$4.67000","currency":"USD"},{"qty":10,"price":"$4.19500","currency":"USD"},{"qty":25,"price":"$3.96640","currency":"USD"},{"qty":100,"price":"$3.43750","currency":"USD"},{"qty":250,"price":"$3.26120","currency":"USD"},{"qty":500,"price":"$2.92624","currency":"USD"},{"qty":1000,"price":"$2.46792","currency":"USD"},{"qty":2500,"price":"$2.34452","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/38da68c5c96f901a806ff40694a48e59.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2955IRHA40R/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430G2955IRHA40R discontinued or active?","answer":"It is Active per TI's product status."},{"question":"What is the flash memory size of MSP430G2955IRHA40R?","answer":"56 KB (56K x 8) of Flash program memory.
