Electrical Specifications – I DD Specifications and Conditions
2. This parameter applies to die devices only (does not include package capacitance).
3. This parameter is not subject to production testing. It is verified by design and character-
ization. The capacitance is measured according to JEP147 (procedure for measuring in-
put capacitance using a vector network analyzer), with V DD1 , V DD2 , V DDQ , V SS , V SSCA , and
V SSQ applied; all other pins are left floating.
4. Absolute value of C CK - C CK# .
5. C I applies to CS#, CKE, and CA[9:0].
6. C DI = C I - 0.5 × (C CK + C CK #).
7. DM loading matches DQ and DQS.
8. MR3 I/O configuration drive strength OP[3:0] = 0001b (34.3 ohm typical).
9. Absolute value of C DQS and C DQS# .
10. C DIO = C IO - 0.5 × (C DQS + C DQS# ) in byte-lane.
11. Maximum external load capacitance on ZQ pin: 5pF.
Electrical Specifications – I DD Specifications and Conditions
The following definitions and conditions are used in the I DD measurement tables unless
stated otherwise:

LOW: V IN ≤ V IL(DC)max
HIGH: V IN ≥ V IH(DC)min
STABLE: Inputs are stable at a HIGH or LOW level
SWITCHING: See the following three tables
Table 56: Switching for CA Input Signals

Notes:
1. CS# must always be driven HIGH.
2. For each clock cycle, 50% of the CA bus is changing between HIGH and LOW.
3. The noted pattern (N, N + 1, N + 2, N + 3...) is used continuously during I DD measure-
ment for I DD values that require switching on the CA bus.
