The 8-channel 10-bit ADC handles analog inputs. That means it is no longer in production and no last-time-buy window remains open. ## 38 I/O and the 100-LQFP footprint — board-fit check With 38 general-purpose I/O lines in a 100-pin LQFP package (14x14 mm body), this MCU offers a moderate pin count for a 100-pin part — many of the pins are tied to the rich peripheral set.","metaTitle":"LM3S8738-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S8738-EQC50-A2T Stellaris ARM Cortex-M3S 8000 MCU, 50MHz, 128KB Flash, 64K x 8 RAM, CAN/Ethernet, -40°C to 105°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":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 8000","Package":"Tape & Reel (TR)","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":"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":"LM3S8738","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":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S8738-EQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S8738-EQC50-A2T obsolete?","answer":"It is no longer in production and there is no active last-time-buy window.
