[1] Typical ratings are not guaranteed. The values listed are at room temperature (25 C), nominal supply voltage.
[2] Based on characterization. Not tested in production.
[3] With respect to ground.
[4] Allowed as long as the current limit does not exceed the maximum current allowed by the device.
[5] To VSS
.
[6] The values specified are simulated and absolute values, including package/bondwire capacitance.
[7] The weak pull-up resistor is connected to the VDD rail and pulls up the I/O pin to the VDD level.
[8] The value specified is a simulated value, excluding package/bondwire capacitance.
[9] Without 33 Ω 2 % series external resistor.
[10] The parameter values specified are simulated and absolute values.
