The 14 general-purpose I/O lines handle local control and status, while SPI and UART/USART connectivity link to external communication modules or data loggers. The surface-mount package suits automated assembly lines, and the Tape & Reel or Cut Tape shipping options match both prototype and production volume. ## Memory and peripheral budget for the BOM With 16 KB of Flash and 512 bytes of RAM, this MCU fits firmware that is single-function and deterministic — think a metering algorithm with a periodic LCD update, not a multitasking RTOS with large data buffers. The 8.4 MHz core speed is enough to execute the metering math (multiply-accumulate for power calculation) within a line-cycle window, but leaves no headroom for software-driven protocol stacks. The three 16-bit ADCs can sample voltage and current channels simultaneously, which is the typical architecture for a basic energy-measurement front-end. The brown-out detect and POR circuits reduce external supervisor IC cost. ## Lifecycle and sourcing posture That said, the MSP430FE4xx series is a mature portfolio; keep an eye on TI's PCN notifications for any future transition. For BOM resilience, the base product number MSP430FE425 covers multiple package and temperature variants, so a shift to a different suffix (e.g., MSP430FE425IPM) is possible if the Tape & Reel option becomes constrained.","metaTitle":"TI MSP430FE425IPMR 16-bit MCU, 16KB Flash, 8.4 MHz, 64-LQFP","metaDescription":"Texas Instruments MSP430FE425IPMR 16-bit MCU, 8.4 MHz, 16KB Flash, 512B RAM, 3x16b ADC, LCD controller, -40 to 85°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"8.4MHz","title":"MSP430FE425IPMR","Series":"MSP430x4xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"512 x 8","Core Size":"16-Bit","Peripherals":"Brown-out Detect/Reset, LCD, POR, PWM, WDT","Connectivity":"SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"14","Core Processor":"MSP430 CPU16","Package / Case":"64-LQFP","Data Converters":"A/D 3x16b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FE425","Program Memory Size":"16KB (16K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6462","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a976cf09b30407f9c28cdb3936d77ff6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can MSP430FE425IPMR be used for energy metering applications?","answer":"Yes — the integrated three 16-bit sigma-delta ADCs and LCD controller are specifically designed for single-phase energy metering.
