At that speed the flash needs zero wait states, so instruction fetch is single-cycle — no pipeline bubble to budget for. The internal oscillator is stable enough for UART and SPI timing at 8 MHz, but if you need a precision baud clock for the USART at higher rates, plan on an external crystal. The 8 MHz limit also sets the ADC sampling rate: with the 12-bit ADC clocked from the internal DCO, you get about 200 ksps aggregate across the 12 channels — adequate for multi-channel sensor scanning in a panel meter or flow controller. ## Integrated LCD driver and dual DAC — fewer external parts This is one of the few MSP430x4xx parts that packs both an LCD segment driver and dual 12-bit DACs on-chip. The LCD controller drives up to 160 segments directly, which eliminates a separate display driver IC in metering and instrumentation panels. The two DACs can generate analog setpoints or bias voltages without external converters. Combined with the 12-channel 12-bit ADC and the DMA controller, the FG439 can run a sensor-front-end plus display update loop without waking the CPU for every conversion — the DMA moves ADC results to RAM while the core sleeps at sub-µA levels. ## Industrial temperature range and 80-LQFP footprint The 48 GPIOs give enough headroom for a parallel LCD data bus plus a handful of sensor interrupts and a UART/SPI port. The brown-out detect and POR circuits are built in — no external supervisor needed for reliable power-up sequencing. At 8 MHz active current is around 2.5 mA typical; in LPM3 (real-time clock + LCD retention) the draw drops to below 2 µA.","metaTitle":"Texas Instruments MSP430FG439IPNR 16-bit MCU, 8 MHz","metaDescription":"Texas Instruments MSP430FG439IPNR 16-bit MCU with 8 MHz core, 60 KB Flash, 2 KB RAM, 12x12b ADC, 2x12b DAC, LCD driver, -40°C to 85°C, 80-LQFP.","metaKeywords":null},"attributes":{"series":"MSP430x4xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x4xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT","Connectivity":"SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"48","Core Processor":"MSP430 CPU16","Package / Case":"80-LQFP","Product Status":"Active","Data Converters":"A/D 12x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FG439","Program Memory Size":"60KB (60K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"80-LQFP (12x12)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.1700","priceTiers":[{"qty":1,"price":"$12.17000","currency":"USD"},{"qty":10,"price":"$10.99100","currency":"USD"},{"qty":25,"price":"$10.47960","currency":"USD"},{"qty":100,"price":"$9.09940","currency":"USD"},{"qty":250,"price":"$8.69040","currency":"USD"},{"qty":500,"price":"$7.92360","currency":"USD"},{"qty":1000,"price":"$6.90120","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/78436a2334e15d18bf48ffba93cac402.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FG439IPNR/alternatives.json"},"ai":{"faq":[{"question":"How does MSP430FG439IPNR compare to MSP430F449IPNR?","answer":"The MSP430FG439 adds dual 12-bit DACs and a 12-channel 12-bit ADC versus the F449's 8-channel ADC and no DAC.
