The 6-channel 10-bit ADC is integrated, saving an external converter for basic analog inputs. That covers outdoor telecom cabinets, factory-floor automation, HVAC controllers, and engine-bay-adjacent electronics that see cold starts but not under-hood heat. ## Peripherals and connectivity — what's on the bus On the peripheral side you get a brown-out detect and POR for supply supervision, a PWM module for motor or LED drive, and a watchdog timer. The 30 I/O lines are adequate for a compact control board with a keypad, display, and a few sensors. ## Lifecycle — active, no LTB shadow The base product number LM3S817 covers the family, and the -IGZ50 suffix locks in the 50 MHz speed grade.","metaTitle":"LM3S817-IGZ50-C2 Stellaris ARM Cortex-M3 MCU, 50MHz","metaDescription":"LM3S817-IGZ50-C2 32-bit ARM Cortex-M3 MCU from the Stellaris 800 series. 50MHz core, 64KB Flash, 8KB SRAM, 30 I/O, 6x10b ADC, industrial temp -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 800","Package":"Tray","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"30","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-VFQFN Exposed Pad","Data Converters":"A/D 6x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S817","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-VQFN (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c076c2f838e276f7287b4eb345e697c1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LM3S817-IGZ50-C2 have I2C?","answer":"No. The listed serial interfaces are Microwire, SPI, SSI, and UART/USART.
