PIN DESCRIPTIONS
Addresses (A
The Address inputs select an 8-bit memory location
during a read or write operation.
Chip Enable (CE)
The Chip Enable input must be LOW to enable all read/
write operations. When CE is HIGH, power consumption
is reduced.
Output Enable (OE)
The Output Enable input controls the data output buffers
and is used to initiate read operations.
Data In/Data Out (I/O
Data is written to or read from the X28HT010 through the
I/O pins.
Write Enable (WE)
The Write Enable input controls the writing of data to the
X28HT010.
Back Bias Voltage (V
It is required to provide -3V on pin 1. This negative
voltage improves higher temperature functionality.
