Real throughput lands lower because flash wait states add cycles above ~8 MHz — the exact number depends on the supply voltage and temperature. For a sensor node polling a 10-bit ADC channel at 200 ksps and logging to flash, the DMA engine (listed among the peripherals) keeps the core sleeping between samples, so the 25 MHz headroom is only tapped during burst processing. ## 128 KB flash, 8 KB RAM — sizing the BOM 128 KB of program flash and 8 KB of SRAM place this MSP430F5xx variant in the mid-range of the family. The flash holds a full protocol stack (say, a Modbus RTU slave with a 2 KB bootloader) plus the application code, leaving roughly 40 KB free. The 8 KB RAM is the tighter resource — a 2 KB DMA buffer for UART reception plus a 1 KB stack leaves 5 KB for sensor data arrays. If your application needs to buffer a full Ethernet frame or a large LCD frame buffer, step up to the 16 KB RAM variants in the same package. ## Peripheral set — what connects, what does not The connectivity block includes I²C, SPI, UART/USART, and IrDA — enough for a typical sensor hub talking to an external EEPROM, an ADC, and a radio module over SPI. There is no on-chip USB, CAN, or Ethernet MAC; those require an external bridge chip. The 12-channel 10-bit ADC is adequate for reading thermistors, potentiometers, and battery voltage dividers, but not for precision analog loops that need 12+ bits. The brown-out detect (BOR) resets the core if the supply dips below the threshold, which prevents flash corruption during a slow battery discharge. ## Package and temperature grade Housed in a 64-VFQFN with an exposed pad (9×9 mm body), the MSP430F5249IRGCT requires a thermal via array under the pad for the -40 to 85 °C industrial range. The 53 I/O lines are all 5 V-tolerant on the digital pins, so level translation is not needed for legacy 5 V peripherals.","metaTitle":"TI MSP430F5249IRGCT MCU, 16-bit 25MHz, 128KB Flash, 64-VQFN","metaDescription":"Texas Instruments MSP430F5249IRGCT, 16-bit MSP430 CPUXV2 at 25MHz, 128KB FLASH, 8KB RAM, 53 I/O, 1.8-3.6V, -40 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":"8K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"53","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":"MSP430F5249","Program Memory Size":"128KB (128K 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":"$8.5500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8abd730fdd3ffc0ef6e39818824c7e56.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F5249IRGCT/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430F5249IRGCT in the MSP430F5xx family?","answer":"Within the same 64-VQFN footprint, the MSP430F5259IRGCT offers 256 KB flash and 16 KB RAM — double the memory — while keeping the same 25 MHz CPUXV2 core, peripheral set, and pinout. The trade-off is a higher unit cost and slightly higher active current.
