In a three-phase energy meter, each phase voltage and current pair needs a dedicated ADC channel; this part covers that with one converter per phase plus a fourth for neutral or reference. That integration removes the need for an external multi-channel ADC or a front-end analog multiplexer, shrinking the BOM and board area. The 32 KB RAM provides enough working space for the accumulated energy registers and communication buffers without external SRAM. The 512 KB Flash holds the application code, calibration constants, and a logging buffer for several months of interval data. ## Package and temperature grade for the environment The MSP430F67491IPEU is supplied in a 128-pin LQFP package with a 20x14 mm body. The surface-mount footprint is standard for this pin count; the 0.5 mm pitch requires careful solder-paste stencil design for reliable reflow.","metaTitle":"TI MSP430F67491IPEU 16-bit MCU, 25 MHz, 512 KB Flash","metaDescription":"Texas Instruments MSP430F67491IPEU 16-bit MCU with CPUXV2 core, 25 MHz speed, 512 KB Flash, 32 KB RAM, 4x24b sigma-delta ADC, 90 I/O, 128-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F6xx","Package":"Tube","RAM Size":"32K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT, 4x24b Sigma Delta Converter","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"90","Core Processor":"MSP430 CPUXV2","Package / Case":"128-LQFP","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67491","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"128-LQFP (20x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.5957","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1d936692bdf96be1c11834add858bc2a.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67491IPEU","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67491IPEU when reusing this data.
