The brown-out detect and POR are on-chip, so the external reset supervisor can be omitted in cost-sensitive builds. The 4x24-bit sigma-delta converters are the headline analog block — they sample multiple phases directly, which is why this part replaces a separate ADC + MCU two-chip solution in polyphase meters. The 8x10-bit auxiliary ADC handles the non-critical analog inputs (temperature, tamper detect) without adding a second converter. ## Sourcing and lifecycle — active part, no LTB pressure For dual-sourcing resilience, the MSP430F6xx family includes pin-compatible density variants sharing the same 128-LQFP footprint — qualifying a second Flash/RAM tier now avoids a sole-source lock if the build forecast shifts.","metaTitle":"TI MSP430F6746AIPEUR 16-bit MCU, 25MHz, 256KB Flash","metaDescription":"Texas Instruments MSP430F6746AIPEUR 16-bit MCU with CPUXV2 core at 25MHz, 256KB Flash, 16KB RAM, 4x24-bit SD ADC, LCD driver, -40 to 85°C.","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":"Tape & Reel (TR)","RAM Size":"16K 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":"MSP430F6746","Program Memory Size":"256KB (256K 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":"$8.5244","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/87bbda703b256feee860450caa184c15.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MSP430F6746AIPEUR have an internal oscillator?","answer":"Yes, it includes an internal oscillator, so no external crystal is required for the core clock.
