Our TSMC 65nm IO Library offering includes:
- Built-in 55um inline pitch wirebond pads.
- Dual independent IO supply rails (1.0-3.3V & 3.3V) and controls to place IOs in a low-power HiZ state during power-down.
- Pulse-width modulation (PWM) output cell, I2C & SVID open-drain cells, 3.3V & 5V analog cells, OTP programming cell & associated ESD.
- Filler, corner, and digital / analog bus break cells.
