Notes
Preliminary
Notes
1. All voltages referenced to VSS.
2. This parameter is sampled. VDD, VDDQ = +1.8V; TA = 25°C; ball under test biased at
1.4V. f = 1 MHz.
3. IDD is dependent on output loading and cycle rates. Specified values are obtained
with minimum cycle time and the outputs open.
4. When the device is in self refresh mode, the on-chip refresh oscillator and address
counters are enabled.
5. The minimum specifications are used only to indicate cycle time at which proper
operation over the full temperature range (-25°C ≤ TA ≤ +85°C for standard parts; -
40°C ≤ TA ≤ +70°C for IT parts) is ensured.
6. An initial pause of 100s is required after power-up, followed by two AUTO REFRESH
commands, before proper device operation is ensured. (VDD and VDDQ must be pow-
ered 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 require-
ment is exceeded.
7. AC characteristics assume tT = 1ns.
8. In addition to meeting the transition rate specification, the clock and CKE must tran-
sit between VIH and VIL (or between VIL and VIH) in a monotonic manner.
9. Outputs measured for 1.8V at 0.9V with equivalent load:
10. tHZ defines the time at which the output achieves the open circuit condition; it is not
a reference to VOH or VOL. The last valid data element will meet tOH before going
High-Z.
11. AC timing and IDD tests have VIL and VIH, with timing referenced to VIH/2 = crossover
point. If the input transition time is longer than tT (MAX), then the timing is refer-
enced at VIL (MAX) and VIH (MIN) and no longer at the VIH/2 crossover point.
12. Other input signals are allowed to transition no more than once every two clocks and
are otherwise at valid VIH or VIL levels.
13. IDD specifications are tested after the device is properly initialized.
14. Timing actually specified by tCKS; clock(s) specified as a reference only at minimum
cycle rate.
15. Timing actually specified by tWR plus tRP; clock(s) specified as a reference only at
minimum cycle rate.
16. Timing actually specified by tWR.
17. Required clocks are specified by JEDEC functionality and are not dependent on any
timing parameter.
18. The IDD current will increase or decrease proportionally according to the amount of
frequency alteration for the test condition.
19. Address transitions average one transition every 2 clocks.
20. CLK must be toggled a minimum of two times during this period.
21. Based on tCK = 8ns for -8 and tCK = 9.6ns for -10.
22. 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.
