0 Spartan-IIE 1.8V FPGA Family: DC and Switching Characteristics R DS077-3 (v1.0) November 15, 2001 0 0 Preliminary Product Specification Definition of Terms In this document, some specifications may be designated as Advance or Preliminary. These terms are defined as follows: Advance: Initial estimates based on simulation and/or extrapolation from other speed grades, devices, or families. Values are subject to change. Use as estimates, not for production. Preliminary: Based on preliminary characterization. Further changes are not expected. Except for pin-to-pin input and output parameters, the AC parameter delay specifications included in this document are derived from measuring internal test patterns. All specifications are representative of worst-case supply voltage and junction temperature conditions. The parameters included are common to popular designs and typical applications. All specifications are subject to change without notice. Specifications are Preliminary for the XC2S50E, XC2S100E, XC2S200E, and XC2S300E, -6 speed grade. Specifications for the XC2S150E and -7 speed grade (all devices) are Advance Information. DC Specifications Absolute Maximum Ratings (1) Symbol Description Min Max Units VCCINT Supply voltage relative to GND -0.5 2.0 V VCCO Supply voltage relative to GND -0.5 4.0 V VREF Input reference voltage -0.5 4.0 V VIN Input voltage relative to GND (2,3) -0.5 4.0 V VTS Voltage applied to 3-state output(3) -0.5 4.0 V TSTG Storage temperature (ambient) -65 +150 C - +125 C TJ Junction temperature Notes: 1. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions is not implied. Exposure to Absolute Maximum Ratings conditions for extended periods of time may affect device reliability. 2. VIN should not exceed VCCO by more than 3.6V over extended periods of time (e.g., longer than a day). 3. Maximum DC overshoot must be limited to either VCCO + 0.5V or 10 mA, and undershoot must be limited to -0.5V or 10 mA, whichever is easier to achieve. The Maximum AC conditions are as follows: The device pins may undershoot to -2.0V or overshoot to VCCO + 2.0V, provided this over/undershoot lasts no more than 11 ns with a forcing current no greater than 100 mA. 4.

Be careful when using foldback/crowbar supplies and fuses. It is possible to control the magnitude of ICCPO by limiting the supply current available to the FPGA. A current limit below the trip level will avoid inadvertently activating over-current protection circuits. Spartan-IIE FPGAs require that a minimum supply current ICCPO be provided to the VCCINT lines for a successful power-on. If more current is available, the FPGA can consume more than ICCPO min., though this cannot adversely affect reliability. Symbol I CCPO TCCPO Description Total VCCINT supply current required during power-on VCCINT (2,3) Commercial Industrial ramp time Min(1) Max Units 500 - mA 2 - A 2 50 ms Notes: 1. The ICCPO requirement applies for a brief time (commonly only a few milliseconds) when VCCINT ramps from 0 to 1.8V. 2. The ramp time is measured from GND to 1.8V on a fully loaded board. 3. VCCINT must not dip in the negative direction during power on. 4. Power-on current is measured with VCCINT and VCCO powering up simultaneously. 5. I/Os are not guaranteed to be disabled until VCCINT is applied. DC Input and Output Levels Values for VIL and VIH are recommended input voltages. Values for VOL and VOH are guaranteed output voltages over the recommended operating conditions. Only selected standards are tested. These are chosen to ensure that all Input/Output Standard VIL standards meet their specifications. The selected standards are tested at minimum VCCO with the respective IOL and IOH currents shown. Other standards are sample tested.

Output Jitter is cycle-to-cycle jitter measured on the DLL output clock, excluding input clock jitter. 2. Phase Offset between CLKIN and CLKO is the worst-case fixed time difference between rising edges of CLKIN and CLKO, excluding output jitter and input clock jitter. 3. Phase Offset between Clock Outputs on the DLL is the worst-case fixed time difference between rising edges of any two DLL outputs, excluding output jitter and input clock jitter. 4. Maximum Phase Difference between CLKIN and CLKO is the sum of output jitter and phase offset between CLKIN and CLKO, or the greatest difference between CLKIN and CLKO rising edges due to DLL alone (excluding input clock jitter). 5. Maximum Phase Difference between Clock Outputs on the DLL is the sum of output jitter and phase offset between any DLL clock outputs, or the greatest difference between any two DLL output rising edges due to DLL alone (excluding input clock jitter). 6.
