The 32K x 8 SRAM supports a couple of CAN message buffers and a moderate call stack — watch the heap usage if you are running a TCP/IP stack over the SSI or UART. For new designs, look at the current Stellaris or Tiva C Series parts from TI — they share the Cortex-M3 core and peripheral set but differ in package and memory options. The 100-LQFP (14x14 mm) is a standard gull-wing package with 0.5 mm pitch — straightforward to hand-solder or reflow with a hot-air station. No exposed thermal pad, so the dissipation path is through the leads only; keep the ambient airflow reasonable if running the core and peripherals near the 85°C limit.","metaTitle":"LM3S2412-IQC25-A2 Stellaris ARM Cortex-M3 MCU, 25 MHz","metaDescription":"LM3S2412-IQC25-A2 32-bit ARM Cortex-M3 MCU, 25 MHz, 96 KB Flash, 32K x 8 SRAM, CAN/I2C/SPI/UART, -40°C to 85°C, 100-LQFP.","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":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tray","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":"49","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 3x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2412","Program Memory Size":"96KB (96K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.7591","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2412-IQC25-A2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2412-IQC25-A2 obsolete?","answer":"Yes, TI lists the LM3S2412-IQC25-A2 as obsolete. There is no official direct replacement from TI; for new designs consider current Stellaris or Tiva C Series Cortex-M3 parts. For existing BOMs, we source through independent distribution — submit an RFQ for current availability and pricing."},{"question":"What is the replacement for LM3S2412?","answer":"No official pin-compatible replacement is listed by TI. The Stellaris and Tiva C Series families include Cortex-M3 MCUs with similar peripherals (CAN, I²C, SPI, UART) but different Flash/SRAM sizes and package options. Check the parametric search for a 100-LQFP part with 25 MHz or higher core speed and CAN interface."},{"question":"Where to buy LM3S2412-IQC25-A2?","answer":"The LM3S2412-IQC25-A2 is obsolete, so standard distributor stock is depleted. We source it through our independent supply network — submit an RFQ and we will confirm availability and pricing at quote time."},{"question":"LM3S2412 vs LM3S2110 what are the differences?","answer":"Both are Stellaris Cortex-M3 MCUs in 100-LQFP. The LM3S2412 runs at 25 MHz with 96 KB Flash and 32K x 8 SRAM, and includes CANbus. The LM3S2110 is a lower-end variant — check its datasheet for exact Flash/SRAM sizes and peripheral set; the key difference is typically the CAN interface and memory footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S2412-IQC25-A2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S2412-IQC25-A2 when reusing this data.
