Single-cycle multiply and hardware divide keep interrupt latency predictable for motor-drive and power-conversion applications. ## Industrial temperature grade — deployment envelope The 1.235 V to 1.365 V core supply is tight — the board-level regulator must hold within that window across load steps and temperature. MSL level should be verified from the date-code trace before reflow. For production builds that cannot migrate to a newer Stellaris or Tiva-C series device, the only channel is independent distribution — surplus stock, new-old-stock, or broker-sourced units. Each lot should be inspected for date code consistency and tested for functional compliance before a production run.","metaTitle":"LM3S9D92-IQC80-A1 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9D92-IQC80-A1 Stellaris ARM Cortex-M3 MCU, 80 MHz core, 512 KB Flash, 96 KB RAM, Ethernet/USB/CAN, -40 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":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 9000","Package":"Tray","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"65","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":"LM3S9D92","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)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for LM3S9D92-IQC80-A1?","answer":"Texas Instruments has not published an official direct-replacement part number for the LM3S9D92-IQC80-A1.
