Recommended Operating
Temperature and Supply Voltage(1)
Absolute Maximum Ratings(1)
Truth Table II—Address Counter Control(1,2)
NOTES:
1 . "H" = VIH, "L" = VIL, "X" = Don't Care.
2. Read and write operations are controlled by the appropriate setting of R/W, CE0, CE1, BEn and OE.
3. Outputs are in Pipelined mode: the data out will be delayed by one cycle.
4. ADS and CNTRST are independent of all other memory control signals including CE0, CE1 and BEn
5. The address counter advances if CNTEN = VIL on the rising edge of CLK, regardless of all other memory control signals including CE0, CE1, BEn.
NOTES:
1 . Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated
in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. VTERM must not exceed VDD + 150mV for more than 25% of the cycle time or
4ns maximum, and is limited to < 20mA for the period of VTERM > VDD + 150mV.
NOTES:
1. This is the parameter TA. This is the "instant on" case tempereature.

Recommended DC Operating
Conditions with VDDQ at 2.5V
NOTES:
1. VIL > -1.5V for pulse width less than 10 ns.
2. VTERM must not exceed VDDQ + 125mV.
3 . To select operation at 2.5V levels on the I/Os and controls of a given port, the
OPT pin for that port must be set to VIL (0V), and VDDQX for that port must be
supplied as indicated above.
Recommended DC Operating
Conditions with VDDQ at 3.3V
NOTES:
1. VIL > -1.5V for pulse width less than 10 ns.
2. VTERM must not exceed VDDQ + 150mV.
3 . To select operation at 3.3V levels on the I/Os and controls of a given port, the
OPT pin for that port must be set to VIH (3.3V), and VDDQX for that port must be
supplied as indicated above.
