The 40-VQFN package (6x6 mm) with exposed pad helps thermal management in enclosed or airflow-constrained assemblies. ## Peripherals and brown-out protection The 32 I/O lines give enough headroom for a keypad matrix, LED drivers, or parallel LCD interface alongside the serial buses. The exposed pad on the 40-VFQFN needs a via-stitched ground plane under it for thermal and electrical integrity — without it, continuous operation near 85°C at full I/O load can push junction temperature past the safe limit.","metaTitle":"TI MSP430G2955IRHA40T 16-bit MCU, 16 MHz, 56 KB Flash","metaDescription":"Texas Instruments MSP430G2955IRHA40T 16-bit MCU with 16 MHz CPU, 56 KB Flash, 4K x 8 RAM, 12x10b 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":"$5.5900","priceTiers":[{"qty":1,"price":"$5.59000","currency":"USD"},{"qty":10,"price":"$5.01800","currency":"USD"},{"qty":25,"price":"$4.74400","currency":"USD"},{"qty":100,"price":"$4.11140","currency":"USD"},{"qty":250,"price":"$3.90056","currency":"USD"},{"qty":500,"price":"$3.49994","currency":"USD"},{"qty":1250,"price":"$2.95176","currency":"USD"},{"qty":2500,"price":"$2.80417","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d1f4138556eb2f798ba1df7fe827a157.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2955IRHA40T/alternatives.json"},"ai":{"faq":[{"question":"What are the alternatives to MSP430G2955IRHA40T?","answer":"Within the same MSP430G2xx family, the MSP430G2744IRHA40R shares the same 40-VQFN package, core, speed, and peripheral set but with less Flash.
