XA9572XL-15VQG44Q

Complex Programmable Logic Devices Overview

The AMD XA9572XL-15VQG44Q is a Complex Programmable Logic Device (CPLD) belonging to the XC9500XL family. It features 72 macrocells and 4 logic blocks, providing 1600 usable gates for digital design applications. The device supports System In-Programmability (SIP) with a minimum of 10,000 erase/program cycles, allowing for field updates without removal from the circuit. It operates within a supply voltage range of 3.0V to 3.6V and guarantees a maximum propagation delay of 15 ns. The component is housed in a 44-pin Very Thin Quad Flat Package (VQFP) with a 10x10 mm footprint, suitable for surface-mount assembly. It is rated for commercial temperature operation between 0°C and 70°C.

Complex Programmable Logic Devices Feature Summary

• 15 ns Maximum Delay: Ensures reliable timing performance for standard speed requirements in embedded systems.
• Single Voltage Operation: Designed for 3.0V to 3.6V VCCI/VCCIO supplies, simplifying power management in 3.3V-centric designs.

Complex Programmable Logic Devices Applications

• Address decoding and memory mapping in embedded controllers.
• Bus bridging between different protocol domains or voltage levels.
• Simple state machine implementation for industrial control interfaces.
• Replacement for legacy GALs or PALs in existing hardware designs.

Complex Programmable Logic Devices Procurement Notes

This specific part number indicates an extended temperature variant or specific qualification suffix compared to the standard commercial grade. Verification of the exact temperature rating and RoHS compliance status against the manufacturer's current datasheet is required before procurement, as product lines may have undergone obsolescence notices or packaging changes. Confirm availability through authorized distributors as stock levels fluctuate.

Complex Programmable Logic Devices Selection Notes

Select this component when a drop-in replacement for older XC9500 series devices is needed with improved density. Ensure the design requires only 3.3V I/O levels, as the XC9500XL family does not support lower voltage I/O standards natively. Verify that the 44-pin VQFP package fits the PCB footprint constraints. For higher gate counts, consider the XC95144 or XC95288 variants within the same family.

Complex Programmable Logic Devices Part Context

The XC9500XL family represents an evolution of AMD's (formerly Xilinx) high-performance CPLD technology, utilizing Flash memory technology for non-volatility. This architecture eliminates the need for external configuration PROMs, reducing system cost and board space. The 'XL' designation signifies enhanced speed and density improvements over the original XC9500 series, making it a staple for cost-sensitive digital logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to the proprietary Flash architecture. Potential alternatives include Microchip ATF15xx series CPLDs, though programming tools and logic block architectures differ. Lattice Semiconductor ispMACH 4000ZE series may offer functional equivalence but requires schematic review for I/O compatibility and timing adjustments.
