TI no longer manufactures this specific variant through its standard production lines. That means new-design starts should not target this part; production BOM lines still using it must turn to the independent distribution channel for remaining inventory. We source the MSP430F5229IZQER through our multi-supplier network of franchised and independent distributors. Expect date codes to vary — we screen each reel or tray for authenticity and condition before it ships. The 128 KB of on-chip Flash (organized as 128K x 8) is the entire non-volatile code and constant-data space. For a typical MSP430 application — a sensor node, a handheld controller, or a simple IoT edge gateway — that is enough room for a real-time OS kernel, a protocol stack (e.g., a lightweight TCP/IP or a proprietary sub-GHz radio driver), and the application logic. The 8 KB of RAM (8K x 8) supports moderate data buffering and a small heap; if your design streams audio samples or holds large lookup tables, you will hit the RAM ceiling quickly and need to page data from Flash or move to a part with more SRAM. ## 25 MHz CPUXV2 — where the cycles go The 25 MHz core speed is the maximum clock the CPUXV2 can run from the internal oscillator or an external source. At 25 MHz, a single-cycle instruction executes in 40 ns. That is enough throughput for most 16-bit control loops — motor commutation at a few kHz, PID updates at 10 kHz, or polling a sensor bus at 1 MHz — but it is not a DSP-class number. If your algorithm involves heavy 16x16 multiply-accumulate operations at audio rates, budget for software-emulated math or look for a part with a hardware multiplier. ## 80-ball BGA — footprint and rework realities The 80-BGA MICROSTAR JUNIOR (5x5 mm) package is a fine-pitch ball-grid array. The 5x5 mm body with 80 balls means the ball pitch is approximately 0.5 mm — this is not a hand-solderable package. Assembly requires a solder-paste stencil, a reflow oven with a controlled profile, and X-ray inspection to verify ball wetting. For rework, a hot-air station with a fine nozzle and a preheat plate is the minimum; the risk of adjacent ball bridging or pad lifting is real.","metaTitle":"MSP430F5229IZQER 16-Bit MCU, 25MHz, 128KB Flash, 80-BGA","metaDescription":"Texas Instruments MSP430F5229IZQER 16-bit MCU with CPUXV2 core, 25MHz, 128KB Flash, 8KB RAM, 31 I/O, I²C/SPI/UART, -40°C to 85°C, 80-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":"25MHz","Series":"MSP430F5xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"8K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"31","Core Processor":"MSP430 CPUXV2","Package / Case":"80-VFBGA","Product Status":"Obsolete","Data Converters":"A/D 12x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5229","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"80-BGA MICROSTAR JUNIOR (5x5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/26881fd7774e91b1e027a30ed7f20c54.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F5229IZQER/alternatives.json"},"ai":{"faq":[{"question":"Is the MSP430F5229IZQER obsolete and still available to buy?","answer":"Yes, the MSP430F5229IZQER carries an obsolete lifecycle status — TI no longer manufactures it through standard production.
