Description
The AT34C02 provides 2048 bits of serial electrically-erasable and programmable
read only memory (EEPROM) organized as 256 words of 8 bits each. The first-half of
the device incorporates a software write protection feature while hardware write pro-
tection for the entire array is available via an external pin as well. Once the software
write protection is enabled, by sending a special command to the device, it cannot be
reversed. The hardware write protection is controlled with the WP pin and can be used
to protect the entire array, whether or not the software write protection has been
enabled. This allows the user to protect none, first-half, or all of the array depending
on the application. The device is optimized for use in many industrial and commercial
applications where low-power and low-voltage operations are essential. The AT34C02
is available in space saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead MAP, 8-lead
TSSOP and 8-ball dBGA2 packages and is accessed via a two-wire serial interface. In
addition, it is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 5.5V) versions.
