That does not mean it is instantly discontinued, but TI has flagged it as a mature product with no future development. New designs should look for a current-generation replacement. The ARM Cortex-M3 core at 50 MHz is a solid mid-range performer for control-loop applications and protocol handling. It can handle a UART at 115.2 kbps with headroom, or run a PWM loop at several kilohertz without jitter. The 32-bit architecture and single-cycle multiply help with PID calculations and sensor fusion. For a BOM line, this is the tier that fits between 8-bit MCUs and high-end 120 MHz+ parts — enough for most industrial and IoT edge nodes without over-spending on a faster core you will not use. The 32 KB SRAM gives room for data buffers and a modest heap. If your design needs OTA updates or a larger application, you will bump into the Flash ceiling; if you are logging sensor data or handling large communication packets, the SRAM may be tight. For a fixed-function controller (motor drive, simple HMI, protocol gateway), it is a comfortable fit. ## 108-ball BGA — rework and field reality The 108-ball LFBGA (10x10 mm) is a fine-pitch BGA. That means no socket, no hand-solder field swap — you need a rework station with a hot-air nozzle and a stencil for reballing. Not a part you carry in a field kit for a parking-lot repair. If your application demands field-replaceability, consider a socketed or QFP variant in the same family. For factory-built boards with no planned field repair, the BGA saves board area and gives better thermal and electrical performance.","metaTitle":"LM3S1435-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S1435-IBZ50-A2T 32-bit ARM Cortex-M3 MCU, 50 MHz, 96 KB Flash, 32 KB SRAM, 46 I/O, 108-BGA, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 1000","Package":"Tape & Reel (TR)","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"46","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Not For New Designs","Data Converters":"A/D 2x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1435","Program Memory Size":"96KB (96K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.8730","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38b03106a267df1019dd902dd40d5344.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1435-IBZ50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S1435-IBZ50-A2T obsolete?","answer":"It is not yet discontinued, but TI has flagged it as mature.
