XCR3256XL-10PQ208C

Overview

The XCR3256XL-10PQ208C is an Electrically Erasable Programmable Logic Device (EE PLD) manufactured by AMD Xilinx. It operates with a maximum clock frequency of 88 MHz and features a propagation delay of 10 ns. The component provides 164 I/O lines and is housed in a 208-pin Plastic Quad Flat Package (PQFP). It supports system-in-programmability and includes JTAG boundary scan capabilities for testing.

Feature Summary

• Electrically Erasable Programmable Logic Device (EE PLD) architecture
• 164 available I/O lines for complex logic interfacing
• System-in-programmable capability allowing field updates
• JTAG BST support for integrated circuit testing

Applications

• Complex glue logic replacement in digital systems
• Address decoding and control signal generation
• Interface bridging between disparate digital components

Procurement Notes

Verify the specific suffix 'C' against official AMD documentation to confirm commercial temperature range specifications. Ensure compatibility with existing PCB footprints for the PQFP-208 package. Confirm lead-free status requirements as historical data indicates varying compliance levels within this product family.

Selection Notes

Select this model when 164 I/Os are required with a 10 ns speed grade. Compare against the -12 variant if slower switching speeds allow for reduced power consumption. Verify that the PQFP-208 package fits within the mechanical constraints of the target enclosure.

Part Context

This part belongs to the XCR3000XL series of EE PLDs from AMD Xilinx. These devices are designed to replace complex discrete logic gates, offering reprogrammability and higher density than traditional GALs. The XL designation typically indicates enhanced performance or feature sets within the standard XCR3000 line.

Replacement Considerations

Direct pin-compatible replacements include the XCR3256XL-10PQ208I for industrial temperature ranges. Other variants in the XCR3256XL family may offer different speed grades or package options.
