The 1.235 V to 1.365 V core supply is narrow; a 1.25 V or 1.3 V LDO with 1% tolerance keeps the core in spec across temperature.","metaTitle":"Texas Instruments LM3S1H11-IQC50-A1 ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments Stellaris LM3S1H11-IQC50-A1 32-bit ARM Cortex-M3 MCU at 50MHz, 512KB Flash, 48KB RAM, 67 GPIO, 100-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":"48K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"EBI/EMI, I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1H11","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/68920ccd04e046c9d0ddb9ddf41bb2dc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1H11-IQC50-A1/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S1H11-IQC50-A1?","answer":"There is no official pin-compatible replacement from Texas Instruments.
