Table 42 Operating Current Measurement Conditions
Symbol Parameter/Condition
IDD0
Operating Current - One bank, Activate - Precharge
tCK=min(tCK), tRC=min(tRC)
Databus inputs are SWITCHING; Address and control inputs are SWITCHING, CS = HIGH between
valid commands.
IDD1
IDD2P
IDD2F
Operating Current - One bank, Activate - Read - Precharge
One bank is accessed with tCK=min(tCK), tRC=min(tRC), CL = CL(min), Address and control inputs are
SWITCHING;
CS = HIGH between valid commands. Iout=0mA
Precharge Power-Down Standby Current
All banks idle, power-down mode, CKE is LOW, tCK=min(tCK), Data bus inputs are STABLE.
Precharge Floating Standby Current
All banks idle; CS is LOW, CKE is HIGH, tCK=min(tCK); Address and control inputs are SWITCHING;
Data bus input are STABLE.
