With 24 KB of Flash and 6 KB of RAM, this MCU fits firmware for a USB CDC class, a Modbus RTU slave stack, or a simple data logger. The 6 KB RAM is organised as 6K x 8, which matches the 16-bit core's byte-addressable architecture. ## 64-VQFN package — footprint and thermal considerations The exposed pad also provides a low-inductance ground return, which helps with EMI on the USB differential pair. The 64-pin count gives access to all 47 I/O plus the USB D+/D− lines, the ADC inputs, and the serial interface pins without multiplexing conflicts for most designs.","metaTitle":"Texas Instruments MSP430F5509IRGCT 16-bit MCU, 25MHz","metaDescription":"Texas Instruments MSP430F5509IRGCT 16-bit MCU with MSP430 CPUXV2 core, 25MHz speed, 24KB Flash, 6KB RAM, USB and serial interfaces, -40°C to 85°C, 64-VQFN","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F5xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"6K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"47","Core Processor":"MSP430 CPUXV2","Package / Case":"64-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 12x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5509","Program Memory Size":"24KB (24K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-VQFN (9x9)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/82530e26136b4d9d3a70005cd9092a5d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F5509IRGCT/alternatives.json"},"ai":{"faq":[{"question":"What package does MSP430F5509IRGCT come in?","answer":"It is supplied in a 64-VFQFN exposed pad package (64-VQFN, 9x9 mm body), surface-mount only."},{"question":"Does MSP430F5509IRGCT have a built-in USB interface?","answer":"Yes, it includes a USB 2.0 interface alongside I²C, SPI, UART, LIN, and IrDA connectivity."},{"question":"What is the closest pin-compatible alternative to MSP430F5509IRGCT in the MSP430F5xx family?","answer":"Pin-compatible alternatives include the MSP430F5510 (32 KB Flash, 6 KB RAM) and MSP430F5519 (64 KB Flash, 8 KB RAM) in the same 64-VQFN package, offering higher memory density without a board spin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F5509IRGCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F5509IRGCT when reusing this data.
