XC9572XL-7CSG48C

Overview

The XC9572XL-7CSG48C is a Complex Programmable Logic Device (CPLD) belonging to the AMD XC9500XL family. It features 72 macrocells, 4 logic blocks, and supports up to 36 user I/O pins. The device operates within a supply voltage range of 4.75V to 5.25V and guarantees a maximum propagation delay of 7.5ns. It utilizes In-System Programmability (ISP) via JTAG, allowing for non-volatile configuration with at least 10,000 erase/program cycles. The component is housed in a 48-ball CSBGA package.

Feature Summary

• XC9500XL architecture providing 72 macrocells and 1600 system gates
• In-System Programmability (ISP) supporting JTAG interface
• Non-volatile Flash technology ensuring data retention without power
• High-speed performance with 7.5ns maximum propagation delay

Applications

• Logic level translation between different voltage domains
• Address decoding and chip select generation
• Simple state machine implementation for control logic
• Bus buffering and protocol conversion

Procurement Notes

Verify the specific suffix 'CSG48C' against official AMD documentation to confirm the package type and temperature grade. As this part number may be discontinued or superseded by newer revisions, cross-reference with current AMD product lifecycle notices to ensure availability and compliance with RoHS standards before procurement.

Selection Notes

Select this component when a moderate density CPLD with ISP capability is required. Ensure the design fits within the 72 macrocell limit and 36 I/O constraint. Verify that the 5V supply requirement aligns with the system power rails. Consider the 7.5ns speed grade if timing constraints are tight for the target application frequency.

Part Context

The XC9572XL is part of the enhanced XC9500 family, offering higher density and lower power consumption compared to the original XC9500 series. It serves as a drop-in replacement for many legacy PAL/GAL applications while providing greater flexibility through Flash-based reprogrammability. The XL series is widely used in industrial and consumer electronics for glue logic functions.

Replacement Considerations

Check for direct pin-compatible replacements such as the XC9572XV or XC9572CL variants if package differences exist. For modern equivalents, consider Lattice ispMACH 4000ZE or Microchip ATF15xx series, ensuring logical equivalence and electrical compatibility.
