The brown-out detect and POR peripherals are calibrated to this narrow band, which means a 3.3V supply run at the low end of tolerance can trigger an unsolicited reset. Any shared-signal level translation between the MCU and 3.3V peripheral devices needs to account for the 2.75V maximum rail. New designs should budget a dedicated LDO for this rail or move to a 3.3V-tolerant MCU variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S8930-IQC50-A2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S8930-IQC50-A2T when reusing this data.
