See Figure 2 for architecture overview. Power Estimation Power dissipation in CPLDs can vary substantially depending on the system frequency, design application and output loading. Each macrocell in an XA9500XL automotive device must be configured for low-power mode (default mode for XA9500XL devices). In addition, unused product-terms and macrocells are automatically deactivated by the software to further conserve power. For a general estimate of ICC, the following equation may be used: ICC(mA) = MC(0.052*PT + 0.272) + 0.04 * MCTOG*MC* f where: MC = # macrocells PT = average number of product terms per macrocell f = maximum clock frequency MCTOG = average % of flip-flops toggling per clock (~12%) This calculation was derived from laboratory measurements of an XA9500XL part filled with 16-bit counters and allowing a single output (the LSB) to be enabled. The actual ICC value varies with the design application and should be verified during normal system operation. Figure 1 shows the above estimation in a graphical form.

All automotive customers are required to set the Macrocell Power Setting to low, and set Logic Optimization to density. 2. Maximum DC undershoot below GND must be limited to either 0.5V or 10 mA, whichever is easier to achieve. During transitions, the device pins may undershoot to -2.0 V or overshoot to +7.0V, provided this over- or undershoot lasts less than 10 ns and with the forcing current being limited to 200 mA. External I/O voltage may not exceed VCCINT by 4.0V. 3. 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. 4.

XA9536XL -15 VQ Example: G 44 I Device Speed Grade Package Type Pb-Free Number of Pins Temperature Range XA9500XL Automotive Requirements and Recommendations Requirements The following requirements are for all automotive applications: 1. All automotive customers are required to keep the Macrocell Power selection set to low, and the Logic Optimization set to density when designing with ISE software. These are the default settings when XA9500XL devices are selected for design. These settings are found on the Process Properties page for Implement Design. See the ISE Online Help for details on these properties. 2. Use a monotonic, fast ramp power supply to power up XA9500XL . A VCC ramp time of less than 1 ms is required. 3. Do not float I/O pins during device operation. Floating I/O pins can increase ICC as input buffers will draw 1-2 mA per floating input. In addition, when I/O pins are floated, noise can propagate to the center of the CPLD. DS598 (v1.1) April 3, 2007 Product Specification I/O pins should be appropriately terminated with keeper/bus-hold. Unused I/Os can also be configured as CGND (programmable GND). 4. Do not drive I/O pins without VCC/VCCIO powered. 5. Sink current when driving LEDs. Because all Xilinx CPLDs have N-channel pull-down transistors on outputs, it is required that an LED anode is sourced through a resistor externally to VCC. Consequently, this will give the brightest solution. 6. Avoid external pull-down resistors. Always use external pull-up resistors if external termination is required. This is because the XA9500XL Automotive CPLD, which includes some I/O driving circuits beyond the input and output buffers, may have contention with external pull-down resistors, and, consequently, the I/O will not switch as expected. 7. Do not drive I/Os pins above the VCCIO assigned to its I/O bank. www.xilinx.com 7 XA9536XL Automotive CPLD R a. The current flow can go into VCCIO and affect a user voltage regulator. b. It can also increase undesired leakage current associated with the device. c. If done for too long, it can reduce the life of the device. 8. Do not rely on the I/O states before the CPLD configures. 9. Use a voltage regulator which can provide sufficient current during device power up. As a rule of thumb, the regulator needs to provide at least three times the peak current while powering up a CPLD in order to guarantee the CPLD can configure successfully. 10. Ensure external JTAG terminations for TMS, TCK, TDI, TDO comply with IEEE 1149.1. All Xilinx CPLDs have internal weak pull-ups of ~50 k on TDI, TMS, and TCK. 11. Attach all CPLD VCC and GND pins in order to have necessary power and ground supplies around the CPLD. 12. Decouple all VCC and VCCIO pins with capacitors of 0.01 F and 0.1 F closest to the pins for each VCC/VCCIO-GND pair. Recommendations The following recommendations are for all automotive applications. 1. Use strict synchronous design (only one clocking event) if possible. A synchronous system is more robust than an asynchronous one. 2. Include JTAG stakes on the PCB. JTAG stakes can be used to test the part on the PCB. They add benefit in reprogramming part on the PCB, inspecting chip 8 internals with INTEST, identifying stuck pins, and inspecting programming patterns (if not secured). 3. XA9500XL Automotive CPLDs work with any power sequence, but it is preferable to power the VCCI (internal VCC) before the VCCIO for the applications in which any glitches from device I/Os are unwanted. 4. Do not disregard report file warnings. Software identifies potential problems when compiling, so the report file is worth inspecting to see exactly how your design is mapped onto the logic. 5. Understand the Timing Report. This report file provides a speed summary along with warnings. Read the timing file (*.tim) carefully. Analyze key signal chains to determine limits to given clock(s) based on logic analysis. 6. Review Fitter Report equations. Equations can be shown in ABEL-like format, or can also be displayed in Verilog or VHDL formats. The Fitter Report also includes switch settings that are very informative of other device behaviors. 7. Let design software define pinouts if possible. Xilinx CPLD software works best when it selects the I/O pins and manages resources for users. It can spread signals around and improve pin-locking. If users must define pins, plan resources in advance. 8. Perform a post-fit simulation for all speeds to identify any possible problems (such as race conditions) that might occur when fast-speed silicon is used instead of slow-speed silicon. 9. Distribute SSOs (Simultaneously Switching Outputs) evenly around the CPLD to reduce switching noise. 10. Terminate high speed outputs to eliminate noise caused by very fast rising/falling edges. www.xilinx.com DS598 (v1.1) April 3, 2007 Product Specification XA9536XL Automotive CPLD R Warranty Disclaimer THIS WARRANTY DOES NOT EXTEND TO ANY IMPLEMENTATION IN AN APPLICATION OR ENVIRONMENT THAT IS NOT CONTAINED WITHIN XILINX SPECIFICATIONS.
