Program memory is 16 KB of Flash with 256 bytes of RAM — enough for metering firmware, signal processing loops, or display-driven control applications. ## 16 KB Flash — sizing the firmware budget The 16 KB Flash (16 K × 8 plus 256 B of information memory) is the program storage. For a typical flow-meter or power-monitor application that reads five analog channels, performs some math, and drives an LCD segment display, this is adequate. But if you plan to add a real-time operating system, a USB stack, or complex floating-point filtering, the 16 KB ceiling will force code-size trade-offs. The 256 B RAM is the working memory — enough for a few frame buffers or a modest call stack, but not for large data arrays. Plan to use the Flash for lookup tables and constants, and keep the RAM for transient variables. ## Integrated 5×16b ADC and 1×12b DAC — BOM consolidation The five 16-bit sigma-delta ADCs and one 12-bit DAC are the headline feature. In a gas-detector or weigh-scale design, these converters eliminate the need for an external ADC or DAC, saving board space and procurement complexity. The 16-bit resolution on the ADC side gives fine granularity for low-level sensor signals; the 12-bit DAC can drive an analog output or a reference input for an external circuit. Note that the converters share the core clock — the 8 MHz CPU speed sets the maximum conversion rate, so factor that into your sampling budget if you need all five channels running continuously. ## Peripherals and I/O — LCD drive, PWM, brown-out The peripheral set includes an LCD driver, PWM channels, a watchdog timer, brown-out reset, and power-on reset. The 32 general-purpose I/O pins are enough to connect a keypad, a small display, and a few external sensors or actuators. ## Package and mounting — 48-pin SSOP The MSP430FG4250IDL comes in a 48-BSSOP (0.295-inch body width, 7.50 mm pitch) surface-mount package, also referred to as the 48-SSOP supplier device package. The 0.65 mm pin pitch is standard for hand-solder rework with a fine-tip iron, though a hot-air station is preferred for production reflow. The package is MSL 3 per TI's standard — bake before reflow if the moisture-barrier bag has been open longer than the floor-life window.","metaTitle":"Texas Instruments MSP430FG4250IDL, 16-bit MCU, 8 MHz","metaDescription":"Texas Instruments MSP430FG4250IDL: 16-bit MSP430 CPU16 at 8 MHz, 16 KB Flash, 256 B RAM, integrated 5x16b ADC & 1x12b DAC, 32 I/O, 1.8V-3.6V, -40°C to 85°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x4xx","Package":"Tube","RAM Size":"256 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, LCD, POR, PWM, WDT","Connectivity":"-","Mounting Type":"Surface Mount","Number of I/O":"32","Core Processor":"MSP430 CPU16","Package / Case":"48-BSSOP (0.295\\\", 7.50mm Width)","Product Status":"Active","Data Converters":"A/D 5x16b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FG4250","Program Memory Size":"16KB (16K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-SSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9826","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2c8d8571f4701aba6780060b9bbb3e99.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the flash memory size of MSP430FG4250IDL?","answer":"The MSP430FG4250IDL has 16 KB of Flash program memory (16 K × 8 plus 256 B of information memory).
