The 256 KB Flash is sized to hold a TCP/IP stack plus a real-time control loop, while the 64 KB SRAM provides enough buffer space for Ethernet frames and CAN message objects. If your firmware image already exceeds 256 KB, this part will not fit without code compression or external memory — plan accordingly. The only channel for procurement is the independent surplus market. ## Ethernet and CAN — the two peripherals that define the part The integrated Ethernet MAC and CAN 2.0 controller are the features that set this MCU apart from simpler Stellaris siblings. If your board needs both a wired network connection and a fieldbus interface without external PHY or CAN transceiver (the PHY is external, but the MAC is on-chip), this part was designed for exactly that combination. The 42 GPIOs and four 10-bit ADC channels round out the peripheral set for sensor and actuator control.","metaTitle":"LM3S8962-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S8962-EQC50-A2T is an obsolete Stellaris ARM Cortex-M3 MCU with 50 MHz core, 256 KB Flash, 64 KB SRAM, Ethernet and 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":"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, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"42","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Obsolete","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S8962","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$45.8003","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6319b5e7f51c1a16fd2cf0eaf85ad587.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S8962-EQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S8962-EQC50-A2T obsolete?","answer":"Yes, the LM3S8962-EQC50-A2T is officially marked Obsolete.

For a similar Stellaris Cortex-M3 with Ethernet and CAN, look at the TM4C series (e.g., TM4C129x) which offers higher performance and more memory, but requires a board respin due to different package and pinout. No drop-in replacement is available from TI."},{"question":"Does LM3S8962-EQC50-A2T support Ethernet?","answer":"Yes, it includes an integrated Ethernet MAC controller. An external PHY chip is required to connect to an RJ45 jack.
