DEVICE OPERATION
Read
Data stored in the CAT28C512/513 is transferred to the
data bus when WE is held high, and both OE and CE
are held low. The data bus is set to a high impedance
state when either CE or OE goes high. This 2-line control
architecture can be used to eliminate bus contention in
a system environment.

Byte Write
A write cycle is executed when both CE and WE are low,
and OE is high. Write cycles can be initiated using either
WE or CE , with the address input being latched on the
falling edge of WE or CE , whichever occurs last. Data,
conversely, is latched on the rising edge of WE or CE ,
whichever occurs first. Once initiated, a byte write cycle
automatically erases the addressed byte and the new
data is written within 5 ms.
