The 18 KB RAM handles packet buffers and real-time data arrays. ## USB and serial connectivity — interface integration note The integrated USB peripheral simplifies adding a USB device port. LINbus and IrDA support can save a separate interface IC. ## Package and temperature grade — design constraints The 113-VFBGA (Microstar Junior 7x7 mm) is a fine-pitch BGA requiring multi-layer PCB and X-ray inspection. ## Obsolete — sourcing reality for sustainment programs That means no further factory orders are accepted; the last-time-buy window has closed. No official TI replacement has been published for this exact order code, so any substitute must be validated for pin-compatibility and firmware porting.","metaTitle":"MSP430F6631IZQWR 16-bit MCU, 20 MHz, 192 KB Flash, 113-BGA","metaDescription":"Texas Instruments MSP430F6631IZQWR 16-bit MCU with MSP430 CPUXV2 core, 20 MHz, 192 KB Flash, 18 KB RAM, USB & serial interfaces, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"20MHz","Series":"MSP430F6xx","Package":"Tape & Reel (TR)","RAM Size":"18K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"74","Core Processor":"MSP430 CPUXV2","Package / Case":"113-VFBGA","Product Status":"Obsolete","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F6631","Program Memory Size":"192KB (192K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"113-BGA Microstar Junior (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e6afd0ec93281fce308ef81d90be6627.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430F6631IZQWR obsolete?","answer":"No further factory production is planned; the part is available only through independent surplus and broker channels."},{"question":"What is the replacement for MSP430F6631IZQWR?","answer":"TI has not published an official direct replacement for this exact order code.
