The base product number MSP430F6746 covers a density and peripheral family, so if a future firmware revision needs more memory or a different ADC configuration, a pin-compatible migration within the MSP430F6xx series is possible without a board spin. ## Package and footprint for the layout engineer The device comes in a 128-pin LQFP package with a 20x14 mm body (supplier device package 128-LQFP). It is a surface-mount, fine-pitch package that requires careful solder-paste stencil design and a reflow profile matching the component's moisture sensitivity level. The 90 I/O lines fan out on all four sides, so a four-layer board with a solid ground plane under the package is the usual starting point. ## Sourcing this part for a production BOM The MSP430F6746IPEU is an active, current-production device from Texas Instruments. If you need a small quantity for a prototype or a repair, the same RFQ process applies; the order code is the same whether you buy one tray or a production reel.","metaTitle":"TI MSP430F6746IPEU 16-bit MCU, 25MHz, 256KB Flash","metaDescription":"Texas Instruments MSP430F6746IPEU 16-bit MCU with 25MHz CPU, 256KB Flash, 16KB RAM, 4x24-bit sigma-delta ADC, LCD driver, 90 I/O.","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":"Tray","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":"$12.2211","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a22d777df21e2845026cc499330e309e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430F6746IPEU and MSP430F6747IPEU?","answer":"The MSP430F6747IPEU is a higher-density sibling in the same MSP430F6xx family. The exact memory and peripheral differences are detailed in the TI datasheet; the key distinction for a buyer is that both share the same 128-LQFP footprint and pinout, so a board designed for one can accept the other with a firmware change. For a sourcing decision, the MSP430F6746IPEU is the lower-cost option when 256 KB Flash and the 4x24-bit ADC are sufficient."},{"question":"What are the full specifications of MSP430F6746IPEU, including core size, speed, and memory?","answer":"Core: 16-bit MSP430 CPUXV2 at 25 MHz.
