5.2.2 I2C timing specifications

BMP581 follows the I²C specification for standard mode, fast mode and fast mode plus. For timing specifications, please

consult the „I2C-bus specification and user manual“, UM10204, Rev.6, NXP Semiconductors. This is valid for the entire

VDDIO voltage range.

5.2.3 I3C timing specifications

BMP581 follows the I3C specification for SDR mode. For timing specifications, please consult the „Specification for I3C

Version 1.1“ and the corresponding errata document „Errata 01 for MIPI I3C Specification“, both from the Mipi Alliance.

For VDDIO < 1.62V, there are deviations from the specification, which are summarized in Table 18.
