Discussion - Hardware / Re: FT4222H reset and Configuration

Responses from FTDI technical Support :
1) "Does the EEPROM chip need to programmed before using the FT4222H ?
-> The OTP does not need to programmed before using the FT4222H.
Please evaluate using the UMFT4222EV : this module OTP is not pre-programmed.
2) "What is the minimum low time for the RESETN signal before VCCIO rising ?"
-> The minimum low time is about 5.2us
