10 / 22 page EBE81FF4ABHT Preliminary Data Sheet E1240E20 (Ver. 2.0) 10 Electrical Specifications • All voltages are referenced to VSS (GND). Absolute Maximum Ratings Parameter Symbol Value Unit Note Voltage on any pin relative to VSS VIN/VOUT –0.3 to +1.75 V AMB core power voltage relative to VSS VCC –0.3 to +1.75 V DRAM interface power voltage relative to VSS VDD –0.5 to +2.30 V Termination voltage relative to VSS VTT –0.5 to +2.30 V Storage temperature Tstg –55 to +100 °C Caution Exposing the device to stress above those listed in Absolute Maximum Ratings could cause permanent damage. The device is not meant to be operated under conditions outside the limits described in the operational section of this specification. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Operating Temperature Conditions Parameter Symbol Value Unit Note SDRAM component case temperature TC _DRAM 0 to +95 °C 1 AMB component case temperature TC _AMB 110 °C Note: 1. Supporting 0°C to +85°C and being able to extend to +95°C with doubling auto-refresh commands in frequency to a 32ms period (tREFI = 3.9 µs) and higher temperature self-refresh entry via the control of EMRS (2) bit A7 is required.
