• Includes configurable dual-port SRAM for flexible memory implementation
• Provides deterministic, user-controllable timing characteristics
• Features unique in-system diagnostic capability via Silicon Explorer II

Applications

• Single-chip ASIC replacement designs
• Automotive applications requiring robust programmable logic
• Industrial control systems needing high resource utilization

Procurement Notes

Verify the specific suffix '3' corresponds to the required commercial temperature grade and voltage specifications. Confirm package integrity for the TQFP-176 form factor against design constraints. Check for any Product Change Notifications (PCN) regarding material or manufacturing site updates. Ensure compatibility with existing PCB footprints and reflow profiles. Validate that the component meets all necessary regulatory standards for the target deployment environment.

Selection Notes

Select this model when 36,000 system gates are required in a 176-pin TQFP package. Choose this variant for designs operating at 3.3V or 5.0V with PCI-compliant I/O requirements. Consider this part for applications needing deterministic timing and in-system diagnostics. Evaluate alternatives if industrial or military temperature ranges are mandatory, as this is a commercial grade device.
