TIMING SPECIFICATIONS

VCC = 3.0 V to 3.6 V, VLOGIC = 1.65 V to 3.6 V, VREF = 2.5 V, and TA = −40°C to +125°C, unless otherwise noted. When referencing a single

function of a multifunction pin in the parameters, only the portion of the pin name that is relevant to the specification is listed, such as ALERT.

For full pin names of multifunction pins, refer to the Pin Configuration and Function Descriptions section.
