XCR3064XL-7VQ100C

Overview

The XCR3064XL-7VQ100C is a Complex Programmable Logic Device (CPLD) from the Xilinx XCR3000XL family, manufactured by AMD. It features 64 macrocells and supports up to 68 I/O pins within a 100-pin VQFP package. The device operates on a 3V to 3.6V supply voltage and offers a maximum operating frequency of 192 MHz with a typical propagation delay of 5.5 ns. It utilizes non-volatile EEPROM technology for configuration storage and is rated for commercial temperature ranges.

Feature Summary

• 64 Macrocells with 68 available I/O pins in a 100-VQFP package
• High-speed performance with 192 MHz max frequency and 5.5 ns propagation delay
• Non-volatile EEPROM memory for instant-on configuration without external PROM
• Single 3V to 3.6V power supply operation

Applications

• System controller logic and interface bridging
• Address decoding and bus arbitration
• State machine implementation in embedded systems
• Replacement for legacy GALs and PALs

Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer channels. Ensure that any sourced units are verified for authenticity and storage history due to the age of the product line.

Selection Notes

Select this part when a low-cost, non-volatile CPLD with moderate I/O count is required. It serves as a drop-in replacement for older E²PROM-based PLDs. Consider the XCR3064XL-10 variant if a slower speed grade (10 ns delay) is acceptable for cost reduction, or the XCR3064XL-7VQG100C if a Quad Flat Package (QFP) is preferred over the Thin QFP form factor.

Part Context

The XCR3000XL series represents an enhanced version of the original XCR3000 CPLD family, featuring improved performance and lower power consumption while maintaining compatibility. This specific model belongs to the 7-ns speed grade within the 64-macrocell segment, designed for general-purpose logic applications where non-volatility and ease of use are prioritized over high-density logic capacity.

Replacement Considerations

Direct pin-to-pin replacements include the XCR3064XL-7VQG100C (different package) and the XCR3064XL-10VQ100C (slower speed grade). For modern equivalents, consider the XCF02S or XC9500XL series, though these may require schematic adjustments due to differences in I/O architecture and voltage levels.
