Characteristics Curves
The following curves demonstrate the characteristic behavior
of the CY25818/19 when tested over a number of environ-
mental and application specific parameters. These are typical
performance curves and are not meant to replace any
parameter specified in Table 4 and Table 5.
Notes:
1. Single Power Supply: The voltage on any input or I/O pin cannot exceed the power pin during power-up.
2. Operation at any Absolute Maximum Rating is not implied.
Table 5. Timing Electrical Characteristics Vdd = 3.3V ±10%, TA = 0°C to +70°C and CL = 15 pF (unless otherwise noted)
