An internal oscillator is on board, so a basic design can start up without an external crystal, though the clock tree supports external sources when tighter timing is needed. ## On-chip data conversion and system monitoring An 8-channel 10-bit ADC is integrated, enough for reading analog sensors, potentiometers, or current-sense resistors without an external converter. DMA offloads the core during data transfers, which matters when you are polling multiple serial interfaces or streaming ADC samples.","metaTitle":"LM3S1J16-IQR50-C1 Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S1J16-IQR50-C1 Stellaris ARM Cortex-M3 MCU, 50MHz core, 128KB Flash, 20KB RAM, 64-LQFP, -40 to 85°C.","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":"20K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"33","Core Processor":"ARM® Cortex®-M3","Package / Case":"64-LQFP","Product Status":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1J16","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4eb1f2120c019042b840bb15071c7cfd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1J16-IQR50-C1/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S1J16-IQR50-C1?","answer":"Texas Instruments does not list a direct pin-compatible successor for this specific order code.
