For serial communication it offers SPI and UART/USART interfaces. The internal oscillator keeps the external crystal optional for non-precision timing, though the clock tree supports an external low-frequency watch crystal for the RTC if the application needs accurate timekeeping. At the low end of the supply range the 8 MHz core speed may need a flash wait state; the datasheet's clock-tree guidance covers that. The MSP430F437IPN comes in an 80-lead LQFP with a 12x12 mm body and 0.5 mm pitch. This is a hand-reworkable package if you have a hot-air station and fine-tipped iron — the leads are visible, the pitch is manageable with flux and braid, and the orientation mark (pin 1 chamfer) is clear. No exposed thermal pad underneath, so the primary heat path is through the leads — keep the ambient airflow reasonable if the part is dissipating more than a few hundred milliwatts.","metaTitle":"TI MSP430F437IPN 16-bit MCU, 8 MHz, 32 KB Flash, 80-LQFP","metaDescription":"Texas Instruments MSP430F437IPN 16-bit MCU with 8 MHz core, 32 KB Flash, 1 KB RAM, LCD driver, 12-bit ADC.","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":"Tray","RAM Size":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, 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 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F437","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":"$18.4900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/67029cd3d4d0eaea057ab2144cff69d7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F437IPN/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430F437IPN?","answer":"Within the MSP430x4xx family, the MSP430F437IPN is part of a pin-compatible density and peripheral set.
