It also integrates an LCD driver, DMA controller, and a brown-out reset circuit, making it a fit for metering, portable instrumentation, and human-machine interface panels where board space and BOM count are tight. The 8 MHz clock keeps dynamic current draw predictable for battery-powered designs. ## Connectivity and peripherals for panel and sensor interfaces Serial communication is handled by a SPI and a UART/USART module — enough for a display, an external EEPROM, or a wireless module. The LCD driver supports up to 160 segments, which covers most alphanumeric or custom-segment glass panels. The DMA engine can move ADC results directly to RAM without CPU intervention, which matters when you are trying to keep the core in sleep mode between samples. ## Package and footprint: 80-LQFP (12x12 mm) The supplier device package is 80-LQFP (12x12). It is ROHS3 compliant.","metaTitle":"Texas Instruments MSP430FG437IPNR 16-bit MCU, 8 MHz","metaDescription":"Active 16-bit MSP430 MCU with 8 MHz core, 32 KB Flash, 1 KB RAM, integrated 12-bit ADC/DAC, SPI/UART, industrial temp -40°C to 85°C.","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":"1K 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":"MSP430FG437","Program Memory Size":"32KB (32K 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":"$11.5500","priceTiers":[{"qty":1,"price":"$11.55000","currency":"USD"},{"qty":10,"price":"$10.43400","currency":"USD"},{"qty":25,"price":"$9.94840","currency":"USD"},{"qty":100,"price":"$8.63800","currency":"USD"},{"qty":250,"price":"$8.24976","currency":"USD"},{"qty":500,"price":"$7.52184","currency":"USD"},{"qty":1000,"price":"$6.55128","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/78436a2334e15d18bf48ffba93cac402.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FG437IPNR/alternatives.json"},"ai":{"faq":[{"question":"Does MSP430FG437IPNR support SPI and UART communication?","answer":"Yes, the connectivity block includes one SPI module and one UART/USART module, sufficient for interfacing with serial peripherals like displays, sensors, or radio modules."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FG437IPNR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FG437IPNR when reusing this data.
