XCR3256XL-12PQG208I

Overview

The XCR3256XL-12PQG208I 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 12 ns. The component provides 164 I/O lines and supports system-in-programmability via JTAG BST. It is housed in a PQFP-208 plastic package, containing 208 pins. The device is classified under ECCN code EAR99 and has a moisture sensitivity level of 3.

Feature Summary

• Maximum operating frequency of 88 MHz
• 164 available I/O lines
• System-in-programmable capability with JTAG support
• 12 ns propagation delay

Applications

• Logic replacement for complex discrete logic circuits
• Address decoding and control signal generation
• Interface bridging between different voltage domains or protocols

Procurement Notes

Verify the specific suffix 'PQG' against official datasheets to confirm pinout compatibility, as standard listings often reference 'PQFP'. Confirm RoHS compliance status, as source data indicates non-compliance for similar variants. Ensure the supplier provides valid traceability documentation for the EAR99 classification.

Selection Notes

Select this model when 164 I/Os are required within a 208-pin QFP footprint. Compare against the FTG256 variant if higher pin counts or BGA packaging are preferred. Verify that the 12 ns speed grade meets the timing requirements of the target application without requiring faster series alternatives.

Part Context

This part belongs to the XCR3000XL family of EE PLDs from Xilinx, now part of AMD. These devices utilize EEPROM technology for non-volatile configuration, allowing for reprogrammability without external memory components. They serve as drop-in replacements for high-density GALs and PALs in industrial and commercial applications.

Replacement Considerations

Direct pin-compatible substitutes include other members of the XCR3000XL family such as the XCR3256XL-10 or XCR3256XL-15, depending on speed requirements. Cross-family replacements like the XC9500XL series require adapter boards or redesign due to architectural differences.
