This means Texas Instruments has formally discontinued production; there is no last-time-buy window remaining through the factory channel. For BOM lines that need this exact order code, supply is limited to existing inventory held in independent distribution and surplus channels. The six 24-bit sigma-delta ADCs are the standout feature of this part. They are designed for simultaneous sampling of multiple voltage and current channels in polyphase energy meters, power-quality monitors, and precision weigh scales. On the BOM, this means you avoid the cost and board area of external ADC ICs and the isolation or level-shifting they would need. The 16-bit CPUXV2 core at 25 MHz has enough headroom to run the metrology algorithms and communication stack without a co-processor, keeping the component count low.","metaTitle":"MSP430F67681IPEUR 16-bit MCU, 25 MHz, 512 KB Flash, 128-LQFP","metaDescription":"Texas Instruments MSP430F67681IPEUR 16-bit MCU with MSP430 CPUXV2 core at 25 MHz, 512 KB Flash, 16K x 8 RAM, six 24-bit sigma-delta ADCs, LCD driver.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F6xx","Package":"Tape & Reel (TR)","RAM Size":"16K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT, 6x24b 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":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67681","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":"$18.1618","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d25833ae3f3e8231a64b1693e0a84f1a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the MSP430F67681IPEUR obsolete?","answer":"Yes, the MSP430F67681IPEUR carries an Obsolete lifecycle status.
