The 8 MHz clock rate is modest by today's standards, but the MSP430 architecture is designed to deliver useful work per cycle at very low current draw. For a polling loop or a periodic sensor readout, the CPU can spend most of its time in a low-power sleep mode and wake only when the ADC or a timer interrupt fires. ## Memory sizing: 60 KB Flash, 2 KB SRAM The 60 KB Flash (organized as 60K x 8 plus 256 bytes) provides enough code space for a moderate firmware stack — a real-time operating system kernel, communication protocol, and sensor calibration tables all fit. The 2 KB SRAM is the tighter resource; data buffers and stack usage need careful budgeting, especially if you are handling multiple UART packets or a display frame buffer. For data-logging applications, external serial EEPROM or FRAM is a common companion. ## Integrated 8-channel 12-bit ADC The on-chip ADC is a 12-bit successive-approximation converter with eight analog inputs. That eliminates an external ADC chip for designs that need to digitise a handful of sensor signals — thermocouples, strain gauges, potentiometers, or current shunts. The 12-bit resolution (4096 counts) is adequate for 0.1% accuracy in most industrial and instrumentation applications. The ADC shares pins with digital I/O, so the firmware must configure the port mux on the channels used. For a production BOM, this removes the urgency to qualify a substitute or stockpile inventory.","metaTitle":"TI MSP430F149IPM 16-bit MCU, 60KB Flash, 8 MHz, 64-LQFP","metaDescription":"Texas Instruments MSP430F149IPM 16-bit ultra-low-power MCU with 60KB Flash, 2KB RAM, 8 MHz CPU, 8-ch 12-bit ADC, SPI/UART, -40°C to 85°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":"MSP430x1xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x1xx","Package":"Tray","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"POR, PWM, WDT","Connectivity":"SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"48","Core Processor":"MSP430 CPU16","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F149","Program Memory Size":"60KB (60K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.6900","priceTiers":[{"qty":1,"price":"$16.69000","currency":"USD"},{"qty":10,"price":"$15.34100","currency":"USD"},{"qty":25,"price":"$14.70520","currency":"USD"},{"qty":160,"price":"$12.95656","currency":"USD"},{"qty":320,"price":"$12.32063","currency":"USD"},{"qty":480,"price":"$11.52575","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2aa7acdd7480e3bd3263b4c69f43f618.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F149IPM/alternatives.json"},"ai":{"faq":[{"question":"Does the MSP430F149IPM have a built-in ADC?","answer":"Yes, it integrates an 8-channel 12-bit successive-approximation ADC, eliminating the need for an external converter in many sensor-front-end designs."},{"question":"What is the difference between MSP430F149IPM and MSP430F149IRTDR?","answer":"The MSP430F149IPM comes in a 64-LQFP tray package, while the MSP430F149IRTDR is a tape-and-reel variant of the same die.
