Power-up Requirements
Power supply sequencing is not required if you are configuring
VDDQ=3.3volts and all power supplies pins are connected to
the same 3.3 volt power supply.
Storage Temperature .................................–65°C to +150°C
Ambient Temperature with
Power Applied.............................................–55°C to +125°C
Power supply sequencing is required if you are configuring
VDDQ=1.5volts. Power must be applied in the following
sequence: VCC (3.3) followed by VDDQ (1.5). Power supply
ramping may occur simultaneously as long as the VCC/VDDQ
relationship is maintained.
VCC Supply Voltage to Ground Potential ....... –0.5V to +4.2V
VDDQ Supply Voltage to Ground Potential ..... –0.5V to +4.2V
DC Voltage Applied to HSTL Outputs
in High-Z State .....................................–0.5V to VDDQ + 0.5V
DC Voltage Applied to Other Outputs
in High-Z State .......................................–0.5V to VCC + 0.5V
