The 36 general-purpose I/O are multiplexed with these peripherals; check the alternate-function map in the datasheet to confirm your signal set fits the 48-LQFP pinout. No official successor part number appears in the lifecycle record, so a pin-compatible drop-in replacement is not guaranteed.","metaTitle":"LM3S601-EQN50-C2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S601-EQN50-C2T 32-bit ARM Cortex-M3 MCU in 48-LQFP. 50 MHz core, 32 KB Flash, 8 KB SRAM, I2C/UART/SPI.

Texas Instruments has classified this part as obsolete. There is no official direct replacement listed, so new designs should avoid it unless you have a stockpile or are servicing an existing BOM through surplus channels."},{"question":"Does LM3S601-EQN50-C2T have I2C and UART peripherals?","answer":"Yes. The connectivity block includes I²C, Microwire, QEI, SPI, SSI, and UART/USART interfaces, so it supports standard serial communication for sensors, displays, and serial links."},{"question":"What is the closest pin-compatible alternative to LM3S601-EQN50-C2T?","answer":"No pin-compatible drop-in replacement is listed in the official lifecycle record. The Stellaris 600 series shares a common Cortex-M3 core and peripheral set across density options, but pin compatibility varies by Flash/RAM size and package variant. Cross-reference the base product number LM3S601 against the LM3S6xx family datasheet to identify a potential second source; without an official cross-reference, treat this as a single-sourced BOM line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S601-EQN50-C2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S601-EQN50-C2T when reusing this data.
