PARAMETER
TEST CONDITIONS
All P-port I/O at VI = VCC or GND(6), IO = 0,
I/O = inputs, fscl = 400 kHz, No load
tr = 3 ns
Operating mode
All P-port I/O at VI = VCC or GND(6), IO = 0,
I/O = inputs, fscl = 400 kHz, No load
tr,max = 300 ns
All P-port I/O at VI = VCC or GND(6), IO = 0,
I/O = inputs, fscl = 100 kHz, No load
ICC
tr,max = 1 µs
Standby mode
All P-port I/O at VI = VCC, IO = 0,
I/O = inputs, fscl = 0 kHz, No load
All P-port I/O at VI = GND, IO = 0,
I/O = inputs, fscl = 0 kHz

Supply current increase (in standby
mode) with one I/O input at specified
voltage level, rather than GND or VCC
