Supply range is 1.8 V to 3.6 V, and the operating temperature covers -40°C to 85°C — the industrial grade that suits factory-floor controllers, outdoor telecom nodes, and automotive body-electronics modules. ## 25 MHz core — timing budget for control loops At 25 MHz, the CPUXV2 pipeline handles sensor fusion loops at a few kilohertz or bit-banged protocols. The 6 KB RAM holds data buffers for UART or SPI streams without external memory. The I²C, SPI, and UART interfaces can operate simultaneously — the USCI modules are independent, so you can talk to an I²C sensor while the SPI bus handles a display and a UART carries debug output. LINbus support makes this part a natural fit for automotive sub-networks like door modules or seat controls. The 8-channel 10-bit ADC samples at rates sufficient for battery monitoring or analog sensor inputs.","metaTitle":"TI MSP430F5309IRGZR 16-bit MCU, 25 MHz, 24 KB Flash, 6 KB RAM","metaDescription":"Texas Instruments MSP430F5309IRGZR, MSP430F5xx series 16-bit MCU with MSP430 CPUXV2 at 25 MHz, 24 KB Flash, 6 KB RAM, 31 I/O, I²C/SPI/UART/LINbus, 1.8–3.6 V, -40 to 85 °C, 48-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","Mounting Type":"Surface Mount","Number of I/O":"31","Core Processor":"MSP430 CPUXV2","Package / Case":"48-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5309","Program Memory Size":"24KB (24K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-VQFN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4945","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5082ceded6d7e8bf3b7144188f002ba0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F5309IRGZR/alternatives.json"},"ai":{"faq":[{"question":"What is the recommended replacement for MSP430F5309IRGZR?","answer":"No official replacement is listed because the part remains active.
