The peripheral set includes Ethernet MAC+PHY, USB OTG, two CAN 2.0B controllers, plus multiple UART, SPI, I²C, and SSI interfaces — enough connectivity to act as a system controller in an industrial gateway or a motor-drive node. ## 512 KB Flash, 96 KB SRAM — sizing the firmware and data budget The 512 KB program memory (Flash) and 96 KB SRAM are well matched for a real-time control application running an RTOS, a TCP/IP stack, and a file system. The 12-bit ADC with 16 channels covers analog sensing — current, voltage, temperature — without an external converter. Brown-out detect and POR keep the core from running on a glitched supply, which matters in an industrial environment with noisy rails.","metaTitle":"LM3S9DN5-IQC80-A1 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S9DN5-IQC80-A1 Stellaris ARM Cortex-M3 MCU: 80MHz core, 512KB Flash, 96KB SRAM, Ethernet/USB/CAN, industrial temp.","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":"72","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":"LM3S9DN5","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":"Where can I buy LM3S9DN5-IQC80-A1?","answer":"Submit an RFQ for current availability and pricing; quotes are confirmed at order time."},{"question":"What are the specifications of LM3S9DN5-IQC80-A1?","answer":"Core speed is 80 MHz.
