There is no official pin-compatible drop-in replacement from TI; the TM4C123x or TM4C129x families offer similar peripherals but in different package options and with a 3.3 V supply. ## Peripherals and on-chip resources Beyond the Ethernet MAC, the LM3S6965 includes a 4-channel 10-bit ADC, PWM outputs, a watchdog timer, and an internal oscillator. The 64 KB SRAM is organized as 64K x 8, adequate for moderate-size packet buffers. The 42 I/O pins are 5 V tolerant on most ports, simplifying level translation when interfacing to legacy 5 V logic or sensors.","metaTitle":"LM3S6965-EQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S6965-EQC50-A2T, Stellaris ARM Cortex-M3S 6000 series, 32-bit MCU at 50 MHz, 256 KB Flash, 64 KB SRAM, Ethernet MAC, -40 to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"50MHz","title":"LM3S6965-EQC50-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":"42","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Data Converters":"A/D 4x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S6965","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":"$44.9494","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3fe7bdc483b32e42e29c70cf5772c9d4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S6965-EQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S6965-EQC50-A2T?","answer":"TI does not list a direct pin-compatible replacement.
