The LM3S8C62-IQC80-A2 is officially marked obsolete. For a production line that already qualifies this footprint and peripheral set, the only path is sourcing verified, date-coded stock through independent distribution. 512 KB of program Flash supports a full embedded TCP/IP stack, a CANopen stack, and a modest application layer without external memory. The 64 KB SRAM handles packet buffers and control data; if the application needs larger DMA buffers or a frame buffer for a display, the external memory interface is absent on this package, so plan the heap accordingly. ## 100-pin LQFP — footprint and routing Housed in a 100-LQFP (14x14 mm) with 46 general-purpose I/O, the part is a fine-pitch SMD that routes comfortably on a four-layer board. The exposed pad (if present on the LQFP) should be stitched to ground with vias for thermal relief — the 80 MHz core and Ethernet PHY can draw enough current to need it. No external oscillator is required; the internal oscillator is rated for operation.","metaTitle":"LM3S8C62-IQC80-A2 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S8C62-IQC80-A2 is an obsolete Stellaris ARM Cortex-M3 MCU with 80 MHz core, 512 KB Flash, 64 KB SRAM, Ethernet, CAN, 16x12-bit ADC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 8000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, Motor Control PWM, POR, PWM, WDT","Connectivity":"CANbus, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"46","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S8C62","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.8900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/60debade6b0451c44918e3de05204f37.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S8C62-IQC80-A2/alternatives.json"},"ai":{"faq":[{"question":"What is a direct replacement for LM3S8C62-IQC80-A2?","answer":"The Stellaris family has been discontinued by TI, so a pin-compatible drop-in may not exist.
