That means TI has stopped production — no further factory orders are accepted. No official replacement order code is recorded in the lifecycle data. If you need a pin-compatible drop-in, the MSP430F5xx family includes multiple density and peripheral variants in the same 113-BGA Microstar Junior footprint — but confirming exact compatibility requires comparing the full pinout and register map against your firmware image. This is a 16-bit MSP430 CPUXV2 microcontroller running at 20 MHz, with 128 KB of program Flash and 18K x 8 of RAM. The 128 KB program space is sized for moderate-complexity firmware — a USB stack, sensor fusion, or a simple RTOS fits, but a full GUI or file system will push the budget. The peripheral set includes USB 2.0 full-speed (with integrated PHY), two SPI/UART/I²C serial interfaces, IrDA, LIN, and a 16-channel 12-bit ADC. ## 113-ball BGA — layout and rework considerations The MSP430F5633IZQWR comes in a 113-VFBGA package, specifically the 7x7 mm Microstar Junior footprint. That's a fine-pitch BGA — 0.5 mm ball pitch typical for this class. The PCB needs via-in-pad or microvias if you route all 74 I/O on a two-layer board; a four-layer stack-up with dedicated power and ground planes is the safer call. BGA rework requires a hot-air station with a bottom preheater and a stencil for solder paste. MSL rating is not in the record, but a 113-ball BGA is typically MSL 3 — bake at 125°C for 24 hours if the moisture-barrier bag has been open longer than the floor-life window.","metaTitle":"MSP430F5633IZQWR 16-bit MCU, 20MHz, 128KB Flash, 113-BGA","metaDescription":"Texas Instruments MSP430F5633IZQWR 16-bit MCU, 20MHz, 128KB Flash, 18Kx8 RAM, USB, 12-bit ADC, 113-BGA.","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":"MSP430F5xx","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":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5633","Program Memory Size":"128KB (128K 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":"$8.2800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/98498aaa47aff8202fed60fe93ff18ce.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430F5633IZQWR obsolete?","answer":"Yes.
