What distinguishes this MCU is its integrated Ethernet MAC, alongside I²C, IrDA, Microwire, QEI, SPI, SSI, and UART/USART interfaces. The LM3S6753-EQC50-A2 is classified as Obsolete by Texas Instruments. The Stellaris family has been superseded by newer Cortex-M4 and M7 families, but no direct pin-compatible replacement with identical peripheral set has been designated by TI for this exact order code. ## 100-LQFP package — layout and rework considerations The 100-LQFP package has a 14x14 mm body.","metaTitle":"LM3S6753-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S6753-EQC50-A2 Stellaris ARM Cortex-M3 MCU with 50MHz core, 128KB Flash, 64KB SRAM, Ethernet, 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":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 6000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"Ethernet, I²C, IrDA, Microwire, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"41","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6753","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2ea3eb04228671d366b848050a50ecdd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6753-EQC50-A2/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S6753-EQC50-A2?","answer":"Texas Instruments has not designated a direct pin-compatible replacement for this exact order code within the Stellaris family. The Stellaris architecture has been superseded by TI's Tiva C Series (Cortex-M4F) and other ARM-based families, but migrating to those requires a software port and potentially a new PCB layout.
