The 46 GPIOs in a 100-pin LQFP leave room for local I/O expansion without an external CPLD. ## On-chip oscillators and debug access An internal oscillator is available, though for CAN and Ethernet timing accuracy an external crystal or oscillator is typical. The JTAG/SWD debug port (not listed in the peripheral summary but standard on Stellaris parts) stays alive even with the watchdog enabled, which simplifies firmware bring-up — you can halt on a hard fault without fighting the reset vector. Supplied in a 100-LQFP (14x14 mm body) — a common footprint shared with other Stellaris 100-pin devices. Surface-mount only.","metaTitle":"LM3S8970-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S8970-IQC50-A2T from Texas Instruments Stellaris series: 32-bit ARM Cortex-M3 at 50 MHz, 256 KB Flash, 64 KB SRAM, CAN/Ethernet/I²C/SPI/UART, -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 8000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, Ethernet, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"46","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S8970","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$33.2805","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6fea3fcd4184acd17fff2b0978d1a133.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S8970-IQC50-A2T/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S8970-IQC50-A2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S8970-IQC50-A2T when reusing this data.
