That means TI will continue to support existing production for a time, but new projects should not start with this order code. For a new design, look at the Stellaris LM3S family's current-generation parts or the TM4C12x series as a functional migration path; check the pin compatibility and peripheral set against your firmware investment. ## CAN bus and connectivity — what is on chip The 46 general-purpose I/O lines give enough headroom for local sensor/actuator interfacing alongside the serial channels. ## Temperature grade and package — board-level fit The 108-LFBGA package (10x10 mm body) requires a multilayer PCB with via-in-pad or microvia routing to escape the fine-pitch balls.","metaTitle":"LM3S2637-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"TI/Stellaris LM3S2637-IBZ50-A2T ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32 KB SRAM, CAN, 108-BGA.","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 2000","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":"CANbus, 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 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2637","Program Memory Size":"128KB (128K 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":"$16.6967","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2637-IBZ50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM3S2637-IBZ50-A2T and get a price?","answer":"Submit an RFQ for current availability and pricing — quotes are confirmed at order time.
