The PYA28C64 is a 5 Volt 8Kx8 EEPROM. Data Retention is 10 Years. PIN CONFIGURATIONS FUNCTIONAL BLOCK DIAGRAM DIP (C5-1) Document # EEPROM105 REV B LCC (L6) NOTE: The RDY/BUSY pin is not connected for the PYA28C64X. Revised June 2012 PYA28C64 - 8K x 8 EEPROM OPERATION READ Read operations are initiated by both OE and CE LOW. The read operation is terminated by either CE or OE returning HIGH. This two line control architecture eliminates bus contention in a system environment. The data bus will be in a high impedance state when either OE or CE is HIGH.
