Recommended operating Temperature

Recommended operating conditions

Notes:

1. OPT pin for a given port must be set to VSS(0V) to operate at VDDQ = 2.5V levels on the I/Os, addresses, clock and controls of that port.

2. OPT pin for a given port must be set to VDD(2.5V) to operate at VDDQ = 3.3V levels on the I/Os, addresses, clock and controls of that port.

DC Electrical Characteristics (VDD = 2.5 V ± 100 mV)

Notes:

1. Outputs disabled (High-Z condition).
