If any of these limits are exceeded, device functionalityshould not be assumed, damage may occur and reliability may be The DC input voltage on any pin should not be lower than V or higher than VCC + V. During transitions, the voltage on any pin mayundershoot to no less than V or overshoot to no more than VCC + V, for periods of less than 20 2.

These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC Q100and JEDEC test Test Condition: Page Mode, VCC = 5 V, 25 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 bytehas to be written, 4 bytes (including the ECC bits) are re-programmed.

6 It is recommended to write by multiple of 4 bytes in order to benefitfrom the maximum number of write 3.

These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC Q100and JEDEC test When not driven, the WP, A1, A2 pins are pulled down to GND internally.

8 For improved noise immunity, the internal pull down is relativelystrong; therefore the external driver must be able to supply the pull down current when attempting to drive the input HIGH. To conserve power,as the input level exceeds the trip point of the CMOS input buffer (~ x VCC), the strong pull down reverts to a weak current 5.
