The LM3S8C62-IQC80-A2T is officially obsolete. Texas Instruments no longer manufactures this part, and no last-time-buy window remains open. There is no direct pin-compatible replacement from TI; a board redesign using a current-generation Stellaris or Tiva-C series MCU is the typical path for new production. ## 80 MHz Cortex-M3 — the performance tier The 80 MHz core speed places this MCU in the mid-range of Cortex-M3 parts. At this clock, the part can handle real-time control loops, Ethernet packet processing, and CAN message handling without external memory. The 64 KB SRAM gives enough headroom for a TCP/IP stack buffer and a modest RTOS heap. If you are evaluating a replacement, the core speed and memory footprint are the first constraints to match. Mounting is surface-mount only.","metaTitle":"LM3S8C62-IQC80-A2T Stellaris Cortex-M3 MCU, 80 MHz","metaDescription":"Texas Instruments LM3S8C62-IQC80-A2T is a 32-bit ARM Cortex-M3 MCU at 80 MHz with 512 KB Flash, 64 KB SRAM, Ethernet, CAN, and 16x12b 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":"Tape & Reel (TR)","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-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S8C62-IQC80-A2T obsolete?","answer":"Yes, the LM3S8C62-IQC80-A2T is obsolete.
