For existing BOM lines, the part remains available through independent distribution while inventory lasts. ## Memory and I/O — sizing the BOM fit The Flash is sufficient for a CANopen stack plus a modest application layer; the 64 KB RAM leaves headroom for multiple packet buffers and a real-time OS kernel. The 60 I/O lines, combined with the CAN, SPI, and UART peripherals, let it serve as a central communication controller on a mixed-signal board without needing an external CPLD for GPIO expansion. ## Package and supply — layout notes","metaTitle":"Texas Instruments LM3S2730-IBZ50-A2T ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S2730-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 32-bit single-core, 50 MHz, 128 KB Flash, 64 KB RAM, 60 I/O, CANbus/SPI/UART, 2.25–2.75 V","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":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"CANbus, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Not For New Designs","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2730","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":"$15.8090","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2730-IBZ50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2730-IBZ50-A2T obsolete or NRND?","answer":"Texas Instruments has flagged it for eventual phase-out, so new designs should avoid it and existing BOM lines should plan for a replacement or last-time-buy."},{"question":"What is the replacement for LM3S2730-IBZ50-A2T?","answer":"For a pin-compatible alternative within the Stellaris family, check the LM3S2730 base number variants — but verify the specific package and temperature grade against your BOM.
