Internal oscillator keeps the clock tree self-contained for many applications. ## Obsolete — sourcing through independent distribution The MSP430F5636IZQWT is officially marked Obsolete by Texas Instruments. No factory orders or last-time-buy windows remain open. The only supply path is the surplus and broker channel, where stock is finite and non-replenishable. For a BOM line that depends on this exact code, the procurement strategy is straightforward: locate available inventory now, qualify it against the original TI datasheet, and plan for a one-time buy that covers the remaining production run. There is no official TI successor listed for this specific variant, so a redesign to a current MSP430 or a different family is the long-term fix. ## Package and footprint — 113-BGA Microstar Junior Housed in a 113-ball VFBGA package (TI's Microstar Junior, 7x7 mm ball array), the MSP430F5636IZQWT is a surface-mount device that requires a multilayer PCB with via-in-pad or microvia capability for routing the fine-pitch balls. The 74 I/O lines give ample room for parallel buses, keypad matrices, and sensor arrays without a port expander. ## What the 20 MHz and 128 KB Flash mean for the design The 20 MHz CPUXV2 core delivers about 20 MIPS — enough for real-time control loops, USB interrupt handling, and moderate DSP math (FIR filters, FFTs up to a few hundred bins). The 128 KB Flash is sized for applications that need a USB stack, a modest RTOS, and application code, but it will fill quickly if you add a GUI library or extensive lookup tables. Plan the memory budget early.","metaTitle":"MSP430F5636IZQWT 16-bit MCU, 20 MHz, 128 KB Flash, Obsolete","metaDescription":"Texas Instruments MSP430F5636IZQWT 16-bit MCU, 20 MHz CPUXV2 core, 128 KB Flash, 18K x 8 RAM, USB, 12-bit ADC/DAC, -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":"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; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5636","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":"$3.9500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1bad71ac48b4349bbe87f462858486d8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430F5636IZQWT obsolete?","answer":"Yes, Texas Instruments lists the MSP430F5636IZQWT as Obsolete.
