The 48 KB Flash (48K x 8 plus 256 bytes) is the program store; it is field-reprogrammable via the internal bootloader or JTAG/SWD. The 2 KB RAM is shared between stack, global variables, and DMA buffers. For applications like a gas meter or blood-glucose monitor that run a state machine with moderate lookup tables, this is adequate. If the firmware grows beyond 48 KB or needs large data arrays, step up to a higher-density MSP430 variant in the same family. ## Integrated LCD driver and analog front-end — BOM consolidation The on-chip LCD controller drives up to 96 segments directly, eliminating a separate LCD driver IC. The 12-bit ADC with 12 multiplexed channels handles sensor inputs (temperature, pressure, battery voltage), while the dual 12-bit DAC can generate analog setpoints or drive a bargraph display. This peripheral set shrinks the BOM count and board area for instrument panels and portable meters. ## 80-LQFP package — footprint and layout notes Decoupling with 100 nF per supply pair and a 4.7 µF bulk cap on the main rail is recommended. The 48 I/O pins are 5 V tolerant, simplifying level translation to external peripherals.","metaTitle":"TI MSP430FG438IPN 16-bit MCU, 8 MHz, 48 KB Flash, 80-LQFP","metaDescription":"Texas Instruments MSP430FG438IPN 16-bit MCU with 8 MHz core, 48 KB Flash, 2 KB RAM, integrated LCD driver, 12-bit ADC/DAC, SPI/UART, industrial temp -40°C to","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":"Tray","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":"MSP430FG438","Program Memory Size":"48KB (48K 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":"$14.2300","priceTiers":[{"qty":1,"price":"$14.23000","currency":"USD"},{"qty":10,"price":"$12.85400","currency":"USD"},{"qty":25,"price":"$12.25560","currency":"USD"},{"qty":119,"price":"$10.64151","currency":"USD"},{"qty":238,"price":"$10.16328","currency":"USD"},{"qty":476,"price":"$9.26651","currency":"USD"},{"qty":952,"price":"$8.07084","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/78436a2334e15d18bf48ffba93cac402.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FG438IPN/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430FG438IPN RoHS compliant?","answer":"Yes, the MSP430FG438IPN is ROHS3 compliant."},{"question":"What is the closest functional second-source for MSP430FG438IPN?","answer":"The TI C2000 F280041PZQR is a 32-bit C28x core MCU at 100 MHz with automotive qualification, but it is a different architecture, pinout, and voltage range.
