The 56 I/O in a 100-LQFP gives plenty of headroom for parallel sensor inputs or a parallel LCD bus, but the 4x10-bit ADC is limited — if you need more than four analog channels or 12-bit resolution, an external ADC or a different MCU tier is required. Texas Instruments no longer manufactures this device, and no direct factory replacement has been assigned to this order code.","metaTitle":"LM3S1635-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S1635-IQC50-A2 32-bit ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32K x 8 RAM, 56 I/O, 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 1000","Package":"Tray","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"56","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":"LM3S1635","Program Memory Size":"128KB (128K 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":"$15.8886","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1635-IQC50-A2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S1635-IQC50-A2 obsolete?","answer":"Yes, the LM3S1635-IQC50-A2 is officially listed as obsolete.
