This part is officially obsolete per the manufacturer. If you have an active BOM line with this order code, you are looking at last-time-buy inventory or new-old-stock — no factory lead times, no guaranteed future availability. The procurement decision is straightforward: source what you can now, or qualify a replacement before the remaining stock dries up. ## What the 25 MHz core and 256 KB Flash buy you The 25 MHz CPUXV2 core is not a speed demon by modern standards, but it is more than adequate for the metering and measurement tasks this chip was designed for. The 256 KB Flash gives you room for a real-time operating system, a calibration table, and several firmware update slots if you use the Flash as program memory. The 16 KB RAM is tight for heavy data buffering — plan your DMA and ADC sample buffers carefully if you are logging all six channels continuously.","metaTitle":"MSP430F67661IPZR 16-bit MCU, 25 MHz, 256 KB Flash","metaDescription":"Texas Instruments MSP430F67661IPZR 16-bit MCU with 25 MHz CPU, 256 KB Flash, 16 KB RAM, six 24-bit sigma-delta ADCs.","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":"62","Core Processor":"MSP430 CPUXV2","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F67661","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.4066","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/867a05e432a8a9b2cd5fa750cee8f989.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy MSP430F67661IPZR?","answer":"Submit an RFQ — we confirm availability and current pricing at quote time against our multi-source network."},{"question":"Is MSP430F67661IPZR obsolete?","answer":"Yes, Texas Instruments lists this part as obsolete.
