That is enough for a real-time OS, a TCP/IP or CANopen stack, and a moderate application layer without resorting to code compression or overlays. The 64K x 8 SRAM supports a few kilobytes of stack, heap, and DMA buffers; if the application needs frame buffers or large lookup tables, plan to use the EBI/EMI interface for external memory expansion. ## 108-ball BGA — footprint and rework notes That is a 10 mm square array with 0.8 mm pitch typical for this ball count — tight enough that hand rework needs a hot-air station with a fine nozzle and a stencil for reballing. The BGA sits on a standard FR-4 land pattern; no exposed pad to stitch, but the inner balls carry the core supply and ground, so decoupling caps should sit within 5 mm of the package perimeter on the top layer.","metaTitle":"LM3S5C31-IBZ80-A1T Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S5C31-IBZ80-A1T is a 32-bit ARM Cortex-M3 MCU from the Stellaris 5000 series. 80 MHz core, 512 KB Flash, 64 KB RAM, USB+CAN, 108-BGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 5000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S5C31","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S5C31-IBZ80-A1T/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM3S5C31-IBZ80-A1T with stock today?","answer":"This obsolete MCU is sourced through independent distribution."},{"question":"Does LM3S5C31-IBZ80-A1T support USB and CAN interfaces?","answer":"Yes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S5C31-IBZ80-A1T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S5C31-IBZ80-A1T when reusing this data.
