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.
