COM-06 — I2C Controller signal levels (EXT_VIO-relative)
draft · Communication
Statement
The I2C Controller shall present input and output voltage levels referenced to the configured EXT_VIO rail, scaling automatically across the supported EXT_VIO range (1.5 / 1.8 / 2.5 / 3.3 V)
Acceptance Criteria
VIH min 0.7×EXT_VIO, max 5.5 V; VIL max 0.4 V when EXT_VIO > 2.2 V, otherwise max 0.1×EXT_VIO; VOL when EXT_VIO > 2.2 V: 0.47–0.6 V (typ 0.52 V); VOL when EXT_VIO < 2.4 V: 0.2–0.3 × EXT_VIO.
