8 / 18 page ® AS7C252MPFD18A 2/11/05, v.1.1 Alliance Semiconductor 8 of 18 Absolute maximum ratings 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 outside those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions may affect reliability. Recommended operating conditions DC electrical characteristics † LBO and ZZ pins have an internal pull-up or pull-down, and input leakage = ±10 µA. *VIH max < VDD +1.5V for pulse width less than 0.2 X tCYC **VIL min = -1.5 for pulse width less than 0.2 X tCYC IDD operating conditions and maximum limits Parameter Symbol Min Max Unit Power supply voltage relative to GND VDD, VDDQ –0.3 +3.6 V Input voltage relative to GND (input pins) VIN –0.3 VDD + 0.3 V Input voltage relative to GND (I/O pins) VIN –0.3 VDDQ + 0.3 V Power dissipation Pd –1.8 W Short circuit output current IOUT – 20 mA Storage temperature Tstg –65 +150 oC Temperature under bias Tbias –65 +135 oC Parameter Symbol Min Nominal Max Unit Supply voltage for inputs VDD 2.375 2.5 2.625 V Supply voltage for I/O VDDQ 2.375 2.5 2.625 V Ground supply Vss 0 0 0 V Parameter Sym Conditions Min Max Unit Input leakage current† |ILI|VDD = Max, OV < VIN < VDD -2 2 µA Output leakage current |ILO|OE ≥ VIH, VDD = Max, OV < VOUT < VDDQ -2 2 µA Input high (logic 1) voltage VIH Address and control pins 1.7* VDD+0.3 V I/O pins 1.7* VDDQ+0.3 V Input low (logic 0) voltage VIL Address and control pins -0.3** 0.7 V I/O pins -0.3** 0.7 V Output high voltage VOH IOH = –4 mA, VDDQ = 2.375V 1.7 – V Output low voltage VOL IOL = 8 mA, VDDQ = 2.625V – 0.7 V Parameter Sym Conditions -200 -166 -133 Unit Operating power supply current1 1 ICC given with no output loading.
