The 8 KB SRAM (organised as 8K x 8) is the tighter constraint: a full-frame 256-point FFT or a large lookup table will eat into that budget quickly. For a dedicated PID loop with encoder feedback and a few analog inputs, the memory map works. ## Peripheral mix — QEI and the motor-control angle The quadrature encoder interface (QEI) is the standout peripheral: it decodes position and velocity from an incremental encoder without CPU overhead, making this MCU a natural fit for brushless DC or stepper motor drives. The 6-channel 10-bit ADC samples at a rate that suits current-sense feedback in a 50 MHz loop. ## Package and power — 48-VQFN with exposed pad Supply range is 3.0 V to 3.6 V — a single 3.3 V rail works, but watch the dropout if you run from a 3.0 V battery at end-of-life.","metaTitle":"LM3S818-IGZ50-C2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S818-IGZ50-C2T 32-bit ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 8 KB RAM, 30 GPIO, 6x10b ADC, -40 to 85°C, 48-VQFN.","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":"Tape & Reel (TR)","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"Microwire, QEI, 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":"LM3S818","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/379f73dc505227f092e37eceebd3371d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM3S818-IGZ50-C2T?","answer":"Within the Stellaris ARM Cortex-M3S 800 series, parts with the same 48-VQFN footprint and supply voltage share the same pinout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S818-IGZ50-C2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S818-IGZ50-C2T when reusing this data.
