Notes
1. VIO < VCC + 200 mV.
2. VIO and VCC ramp must be synchronized during power up.
3. If RESET# is not stable for tVCS or tVIOS
:
The device does not permit any read and write operations.
A valid read operation returns FFh.
A hardware reset is required.
4. VCC maximum power-up current (RST=VIL) is 20 mA.
