The 43 general-purpose I/O lines are brought out on a 100-pin LQFP package (14x14 mm body). The Stellaris family was acquired by TI from Luminary Micro and later phased out in favour of the Tiva-C and Hercules lines. There is no direct pin-compatible replacement from TI — the Tiva TM4C series uses a different pinout and 3.3 V supply. The 50 MHz core speed is the ceiling for instruction throughput — at 1.25 DMIPS/MHz the Cortex-M3 delivers about 62.5 DMIPS. That is adequate for a single Ethernet packet-processing loop with a modest control algorithm, but not for heavy DSP or video. The 2.25 V–2.75 V supply means the I/O levels are 2.5 V nominal — interfacing to 3.3 V peripherals requires level translation or careful selection of 2.5 V-tolerant parts. The 100-LQFP package is a fine-pitch (0.5 mm) surface-mount footprint; rework is possible with hot air but requires a steady hand and a good stencil for production.","metaTitle":"TI LM3S6952-IQC50-A2T ARM Cortex-M3 MCU, 50MHz, 256KB Flash","metaDescription":"Texas Instruments LM3S6952 Stellaris ARM Cortex-M3 MCU: 50MHz, 256KB Flash, 64KB RAM, Ethernet MAC, industrial temp -40°C to 85°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","title":"LM3S6952-IQC50-A2T","Series":"Stellaris® ARM® Cortex®-M3S 6000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"Ethernet, I²C, IrDA, Microwire, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"43","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Data Converters":"A/D 3x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6952","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":"$52.3900","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6952-IQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S6952-IQC50-A2T?","answer":"There is no direct pin-compatible replacement from TI.
