ABSOLUTE MAXIMUM RATINGS Parameters Ratings Units Operating Temperature 0 to +85 C Storage Temperature 10 to +90 C Voltage on any Pin with Respect to Ground (Note 1) 0.5 to +6.5 V Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 1. The DC input voltage on any pin should not be lower than 0.5 V or higher than V + 0.5 V. During transitions, the voltage on any pin may CC undershoot to no less than 1.5 V or overshoot to no more than V + 1.5 V, for periods of less than 20 ns. CC Table 2.

The device uses ECC (Error Correction Code) logic with 6 ECC bits to correct one bit error in 4 data bytes. Therefore, when a single byte has to be written, 4 bytes (including the ECC bits) are reprogrammed. It is recommended to write by multiple of 4 bytes located at addresses 4N, 4(N+1), 4(N+2), 4(N+3), in order to benefit from the maximum number of write cycles. Table 3. D.C.

When not driven, the WP and HOLD inputs are pulled up to V internally. For noisy environments, when the pin is not used, it is CC recommended the WP and HOLD input to be tied to V , either directly or through a resistor. CC
