XC9572XL-10VQ44C

Complex Programmable Logic Devices Overview

The AMD XC9572XL-10VQ44C is a Complex Programmable Logic Device (CPLD) belonging to the XC9500XL series. It features 72 macrocells, 34 I/O pins, and 1600 system gates organized into four Logic Array Blocks (LABs). The device operates at a supply voltage of 3.0 V to 3.6 V with a maximum frequency of 178 MHz and a propagation delay of 10 ns. Packaged in a 44-pin VQFP, it utilizes non-volatile Flash memory for configuration and supports an industrial temperature range of -40°C to +85°C.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash memory architecture eliminates the need for external configuration PROMs.
• In-system programmability allows field updates without removing the device from the circuit board.
• High-density logic resources provide 72 macrocells and 1600 system gates within a compact package.

Complex Programmable Logic Devices Applications

• Address decoding and bus bridging in embedded systems.
• Translation between different logic families or voltage levels.
• State machine implementation for control logic applications.

Complex Programmable Logic Devices Procurement Notes

This component is classified as obsolete and is no longer manufactured by AMD. Availability is restricted to existing stock held by distributors. Verification of part authenticity and storage history is critical due to the component's end-of-life status. Buyers should confirm lead times and pricing directly with suppliers, as inventory levels fluctuate rapidly.

Complex Programmable Logic Devices Selection Notes

Designers requiring this specific pinout and logic density must evaluate current market availability carefully. Alternative components within the XC9500XL family, such as the XC9572XL-10VQG44C, may offer similar specifications but require verification of package compatibility and electrical parameters against the original design requirements before substitution.

Complex Programmable Logic Devices Part Context

The XC9572XL-10VQ44C is part of the XC9500XL product line, which succeeded the original XC9500 series. This generation introduced Flash technology for reprogrammability and improved performance metrics while maintaining compatibility with standard JEDEC programming interfaces. The series was designed to replace discrete logic solutions in cost-sensitive digital designs.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include the XC9572XL-10VQG44C. Other potential replacements within the same family are the XC9572XL-10TQ100C and XC9572XL-7VQ44C, though these differ in package type or speed grade. Cross-referencing datasheets for pin compatibility and timing constraints is mandatory.
