XCR3256XL-10PQG208I

Overview

The XCR3256XL-10PQG208I is an Electrically Erasable Programmable Logic Device (EPLD) manufactured by AMD (formerly Xilinx). It features a 10 ns speed grade and is housed in a 208-pin Plastic Quad Flat Package (PQFP). The device supports system-in-programmability and includes JTAG boundary scan capabilities. Key electrical parameters include a maximum clock frequency of 88 MHz and 164 I/O lines. The component is lead-free compliant with RoHS standards and carries an EAR99 classification.

Feature Summary

• Electrically Erasable Programmable Logic Device (EPLD) architecture
• 10 ns speed grade with 88 MHz maximum clock frequency
• 208-pin PQFP package with 164 I/O lines
• System-in-programmable with JTAG BST support

Applications

• Complex logic replacement in industrial control systems
• Interface bridging between legacy and modern digital components
• State machine implementation in embedded hardware designs

Procurement Notes

Verify the specific speed grade suffix, as the model indicates '10' while reference data may list '12'. Confirm package type matches PQG208 versus PQFP208. Check for lead-free compliance status against current regulatory requirements. Ensure JTAG programming compatibility with existing test infrastructure. Validate manufacturer origin given AMD's acquisition of Xilinx assets.

Selection Notes

Select this EPLD for designs requiring electrically erasable non-volatile configuration without flash-based FPGA complexity. The 10 ns speed grade suits moderate-frequency digital logic applications. Verify that the 164 available I/O lines meet interface requirements. Consider thermal dissipation characteristics inherent to the PQFP package form factor.

Part Context

This component belongs to the XCR3000XL family of EPLDs from Xilinx, now part of AMD's portfolio. These devices bridge the gap between simple GALs and complex FPGAs, offering reprogrammability with deterministic timing. The XL series specifically denotes enhanced performance and density improvements over earlier generations.

Replacement Considerations

Direct pin-compatible replacements within the same family include XCR3256XL-12PQG208I with adjusted timing specifications. Cross-family migration to XC9500XL series requires logic capacity verification. No direct cross-manufacturer equivalents exist due to proprietary architecture.
