Electrical Specifications
Electrical Specifications
Stresses greater than those listed may cause permanent damage to the device. This is a
stress rating only, and functional operation of the device at these or any other condi-
tions above those indicated in the operational sections of this specification is not im-
plied. Exposure to absolute maximum rating conditions for extended periods may affect
reliability.

Notes:
1. All voltages referenced to VSS.
2. Minimum specifications are used only to indicate the cycle time at which proper opera-
tion over the full temperature range is ensured:
–40°C ≤ TA ≤ +85°C (industrial)
–40°C ≤ TA ≤ +105°C (automotive)
3. An initial pause of 100μs is required after power-up, followed by two AUTO REFRESH
commands, before proper device operation is ensured. (VDD and VDDQ must be powered
up simultaneously. VSS and VSSQ must be at same potential.) The two AUTO REFRESH
command wake-ups should be repeated any time the tREF refresh requirement is excee-
ded.
4. VIH overshoot: VIH,max = VDDQ + 2V for a pulse width ≤3ns, and the pulse width cannot
be greater than one-third of the cycle rate. VIL undershoot: VIL,min = –2V for a pulse
width ≤3ns.
