Any cross-reference candidate requires pinout and supply confirmation before assuming drop-in fit."},{"question":"Can the internal oscillator support USB full-speed without an external crystal?","answer":"USB full-speed at 12 Mbit/s requires ±0.25% frequency accuracy. The internal RC oscillator alone will not reliably meet this across the full temperature range. An external crystal on XTAL1/2 is required for compliant USB operation; the internal oscillator may suffice for device enumeration only."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp-usa-inc/LPC2923FBD100~6551","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp-usa-inc/LPC2923FBD100~6551 when reusing this data.
