That means this exact order code is still available for existing production builds, but TI will not support it in a new board spin — no guarantee of long-term supply or future PCN coverage. For a repair bench or a production line that already has this MCU in the BOM, the NRND status is a flag to review the next spin. ## 50 MHz Cortex-M3 with 128 KB flash The core is an ARM Cortex-M3 running at 50 MHz — enough throughput for a CAN-based motor controller, a multi-axis QEI position loop, or a UART-to-CAN gateway without a second MCU. The 128 KB of on-chip flash and 16 KB of SRAM give the firmware stack room for a RTOS kernel, the protocol stack, and the application state machine. The 2.25 V to 2.75 V supply rail is tighter than a typical 3.3 V MCU — the board needs a dedicated regulator, not a shared 3.3 V rail. ## Peripheral set and package On-chip peripherals include CANbus, I²C, IrDA, QEI (quadrature encoder interface), and multiple UART/USART channels — the QEI is the differentiator here, letting the MCU read an incremental encoder directly without an external counter IC. Brown-out detect, POR, watchdog timer, and PWM are also integrated, reducing the external supervisor and timer count. The six-channel 10-bit ADC covers analog inputs like potentiometers or current-sense resistors without an external converter.","metaTitle":"Texas Instruments LM3S2616-IQR50-A0T Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S2616-IQR50-A0T Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB flash, 16 KB RAM, 64-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tape & Reel (TR)","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, QEI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"33","Core Processor":"ARM® Cortex®-M3","Package / Case":"64-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 6x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2616","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.6248","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3dd66401e2a8f19e937d021e486a6280.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2616-IQR50-A0T/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM3S2616-IQR50-A0T?","answer":"A pin-compatible alternative within the same Stellaris Cortex-M3 family would share the 64-LQFP footprint and the same supply voltage range."},{"question":"What compliance documentation does Texas Instruments provide for LM3S2616-IQR50-A0T?","answer":"Texas Instruments provides RoHS and REACH compliance documentation for this part.
