Texas Instruments ended production of the Stellaris LM3S6918-EQC50-A2. If you have an active BOM line using this MCU, you are now dependent on surplus and broker-channel inventory. There is no official TI successor listed in the record; the Stellaris line was folded into the Tiva-C family, but pin-compatibility is not guaranteed without a full design review. The 50 MHz core clock runs a lightweight TCP/IP stack alongside a control loop. The 64 KB SRAM provides about 40 KB of usable heap after the stack and RTOS kernel. The 100-LQFP (14x14 mm) is a surface-mount package.","metaTitle":"LM3S6918-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S6918-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 64 KB 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, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"38","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":"LM3S6918","Program Memory Size":"256KB (256K 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/513ab98429c8d221b314aeae12dda61f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM3S6918-EQC50-A2 obsolete?","answer":"Yes, the LM3S6918-EQC50-A2 carries an Obsolete lifecycle status.
