Our TSMC 22nm IO Library offering includes:

  • Built-in 55um inline pitch wirebond pads.
  • Dynamically switchable 1.8V/3.3V GPIO, 3.3V I2C open-drain cell, 1.8V & 3.3V analog cells & associated ESD.
  • Filler, break, and transition cells.

GPIO Features

Dynamic 1.8V / 3.3V switchable operation
25MHz, 75MHz & 150MHz speed options1
Full-speed output enable/disable (HiZ when disabled)
Independent power sequencing
Shorted output protection (fail safe)
Schmitt trigger receiver
60KΩ selectable pull-up or pull-down resistor
ESD: 2KV HBM, 500V CDM2, 2KV IEC 61000-4-23

1GPIO speeds are load dependent (faster for lighter loads, slower for heavier). Speeds shown are at 10pF
2CDM rating is a function of package size. Rating shown is for nominal packages.
3Please contact a Certus representative for IEC 62100-4-2 protection levels achievable with your design
