DEVICE OPERATION

Read

Data stored in the CAT28C256 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.
