XCR3064XL-7VQG44C

Overview

The AMD XCR3064XL-7VQG44C is a Complex Programmable Logic Device (CPLD) belonging to the XCR3000XL family. It features 64 macrocells and supports up to 40 I/O pins within a 44-pin VQFP package. The device operates on a single supply voltage ranging from 2.7V to 3.6V, with typical operation at 3.3V. Key electrical specifications include a maximum propagation delay of 7ns and a maximum operating frequency of 192MHz. It is designed for industrial temperature ranges, functioning between -40°C and +85°C.

Feature Summary

• 64 Macrocells with non-volatile Flash technology for instant-on functionality
• High-speed performance with 7ns max propagation delay and 192MHz max frequency
• Supports 40 I/O pins with flexible I/O standards including LVTTL and LVCMOS
• Operates on a single 2.7V to 3.6V power supply

Applications

• Address decoding and bus bridging in embedded systems
• Power-on reset generation and clock control circuits
• General-purpose logic replacement in industrial control applications
• Interface translation between different voltage domains

Procurement Notes

Verify the specific suffix '7VQG44C' to confirm the 7ns speed grade and 44-pin VQFP package variant. Confirm RoHS compliance status as manufacturing processes evolve. Check for end-of-life or last-time-buy notices from AMD/Xilinx distributors, as this component belongs to an older CPLD generation.

Selection Notes

Select this part when non-volatile configuration is required without external memory. Ensure the design utilizes a 3.3V logic level compatible with the specified I/O standards. Verify that the 40 available I/O pins meet the interface requirements. Consider thermal dissipation if operating near the upper limit of the -40°C to +85°C range.

Part Context

This component is part of the Xilinx XCR3000XL series, which introduced Flash-based non-volatility to CPLDs. Unlike volatile SRAM-based FPGAs, it retains configuration data without power. The XCR3064XL variant offers a balance of density and speed suitable for mid-complexity logic functions in cost-sensitive applications.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to the age of the Flash CPLD architecture. Potential alternatives include newer Xilinx XC9500XL series devices or competitive CPLDs from Lattice Semiconductor, provided timing and I/O voltage compatibility are verified.
