This means TI no longer recommends it for new projects, and an end-of-life notice is expected. For existing designs, secure a last-time-buy quantity to cover remaining production needs."},{"question":"What is the replacement for LM3S301-EQN20-C2?","answer":"No official direct replacement order code is listed from TI for this exact Stellaris density and package. Migration to a current-generation Cortex-M4 or M0+ part (such as the TM4C series) will require a firmware port and potentially a board layout change. The 48-LQFP footprint may be reused across some Stellaris siblings, but pin compatibility is not guaranteed without checking the respective datasheets."},{"question":"What is the operating voltage of LM3S301-EQN20-C2?","answer":"The supply voltage range is 3.0 to 3.6 V. A 3.3 V regulated rail with ±2% tolerance keeps the MCU within spec across temperature."},{"question":"What are the key specifications of LM3S301-EQN20-C2?","answer":"Key specs include a 32-bit ARM Cortex-M3 core at 20 MHz, 16 KB Flash, 2K x 8 SRAM, 33 GPIOs, 3-channel 10-bit ADC, serial interfaces (Microwire, SPI, SSI, UART/USART), internal oscillator, and an industrial temperature range of -40 to 105 °C in a 48-LQFP package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S301-EQN20-C2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S301-EQN20-C2 when reusing this data.
