Enhanced Super I/O Controller with LPC Interface
Datasheet
Note 1: All output leakage’s are measured with all pins in high impedance.
Note 2: Output leakage is measured with the low driving output off, either for a high level output or a high impedance
Note 3: Contact SMSC for the latest values.
Note 4: Max I
Note 5: Min I
