AT34C02-10PC
AT34C02-10PC Datasheet
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 protection 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-pin PDIP, 8-lead JEDEC SOIC, and 8-lead TSSOP packages and is accessed via a 2-wire serial interface. In addition, it is available in 5.0V 4.5V to 5.5V , 2.7V 2.7V to 5.5V , and 1.8V 1.8V to 5.5V versions.
