SLDS231 August 2018 PGA305
PRODUCTION DATA.
The OWI master initiates OWI communication when the OWI master generates an OWI activation-pulse sequence on the PWR pin. When the PGA305 device receives a valid OWI activation-pulse sequence, it prepares itself for OWI communication. Notice that after the valid OWI activation-pulse sequence is received, the logic checks on the EEPROM lock status. If the EEPROM is locked, the sequence 0x5555 must be sent within 100 ms after the end of the activation-pulse sequence.
