For existing BOM lines, procurement must go through surplus or broker channels. Program memory is 96 KB of Flash, backed by 64 KB of SRAM — enough for moderate firmware stacks running a real-time OS or bare-metal control loop. The 64 KB SRAM gives room for Ethernet packet buffers or CAN message queues without external memory. The 8-channel 10-bit ADC covers analog sensor inputs. Brown-out detect, POR, PWM, and WDT are integrated for supervisory and timing tasks. Housed in a 100-pin LQFP (14x14 mm body), surface-mount.","metaTitle":"LM3S8538-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Obsolete LM3S8538-IQC50-A2 32-bit ARM Cortex-M3 MCU from TI Stellaris series. 50 MHz, 96 KB Flash, 64 KB SRAM, CAN/Ethernet.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","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, POR, PWM, WDT","Connectivity":"CANbus, Ethernet, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"36","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S8538","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":"$14.7200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S8538-IQC50-A2/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S8538-IQC50-A2?","answer":"No official replacement part number is listed for the LM3S8538-IQC50-A2.
