The 100-LQFP footprint and 1.235–1.365 V core supply are tight constraints that limit drop-in alternatives — a redesign to a current TI or NXP Cortex-M3 with integrated Ethernet is the typical path. ## 80 MHz and the connectivity stack The 80 MHz Cortex-M3 core runs a lightweight TCP/IP stack alongside a CANopen or Modbus application. 96 KB of RAM leaves room for packet buffers and control data structures. The 65 GPIOs are enough to drive a local character display, keypad, and a handful of relays or opto-isolated inputs alongside the communication peripherals. Brown-out reset and the watchdog are on-chip, so an external supervisor is optional for most industrial designs.","metaTitle":"LM3S9B95-IQC80-C1T Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"Texas Instruments LM3S9B95-IQC80-C1T, Stellaris ARM Cortex-M3S 9000 series 32-bit MCU. 80 MHz core, 256 KB Flash, 96 KB RAM, Ethernet + USB OTG + dual CAN.","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 9000","Package":"Tape & Reel (TR)","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"65","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9B95","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)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bff979f5f4c64b1ca9266fc9abcdd07a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I source the LM3S9B95-IQC80-C1T and how do I get a quote?","answer":"This part is sourced to order against an RFQ through independent distribution channels — brokers and independent distributors holding remaining stock.
