The speed-related specifications are guaranteed characteristic points along a continuous curve of operation from DC to fSCL (max). 2. This parameter is periodically sampled and not 100% tested. 3. In HS-mode and VDD < 2.7V, the tSU:DAT (min.) spec is 15ns. Capacitance (TA = 25 C, f=1.0 MHz, VDD = 3.3V) Symbol Parameter Min Max Units Notes CI/O Input/Output Capacitance (SDA) - 8 pF 1 CIN Input Capacitance - 6 pF 1 Notes 1. This parameter is periodically sampled and not 100% tested.
