Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The DC input voltage on any pin should not be lower than â0.5 V or higher than VCC + 0.5 V. During transitions, the voltage on any pin may
undershoot to no less than â1.5 V or overshoot to no more than VCC + 1.5 V, for periods of less than 20 ns.

2. These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AECâQ100
and JEDEC test methods.
3. Page Mode, VCC = 5 V, 25°C.
4. The new product revision (E) 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 reâprogrammed. It is recommended to write by multiple of 4 bytes in order
to benefit from the maximum number of write cycles.

5. These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AECâQ100
and JEDEC test methods.
6. When not driven, the WP pin is pulled down to GND internally. For improved noise immunity, the internal pullâdown is relatively strong;
therefore the external driver must be able to supply the pullâdown current when attempting to drive the input HIGH. To conserve power, as
the input level exceeds the trip point of the CMOS input buffer (~ 0.5 x VCC), the strong pullâdown reverts to a weak current source. The
variable WP input impedance is available only for Die Rev. C and higher.
