Features
Description
The Atmel
read only memory (EEPROM) organized as 256 words of eight bits each. The first-half of
the device incorporates a permanent and a reversible software write protection feature
while hardware write protection for the entire array is available via an external pin. Once the
permanent software write protection is enabled, by sending a special command to the
device, it cannot be reversed. However, the reversible software write protection is enabled
and can be reversed by sending a special command. The hardware write protection is con-
trolled 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 AT34C02C is available in space saving 8-lead JEDEC SOIC,
Mini-MAP (MLP 2x3)
wire serial interface. It is available in 1.7V (1.7V to 5.5V).
