XC9572-15PC44C

Complex Programmable Logic Devices Overview

The XC9572-15PC44C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500 series, manufactured using CMOS 5V FastFLASH technology. It features 1600 system gates organized into four Logic Array Blocks (LABs), providing 72 macrocells and up to 34 user I/O pins. The device operates within a commercial temperature range of 0°C to +70°C and utilizes a 44-pin PLCC package. Key electrical specifications include a maximum pin-to-pin propagation delay of 15 ns and a maximum internal frequency of 55.6 MHz. It supports 5V in-system programming with a endurance of at least 10,000 erase/program cycles.

Complex Programmable Logic Devices Procurement Notes

This component is officially listed as obsolete and no longer manufactured by AMD. Verification of availability should focus on third-party distributors holding surplus stock. Buyers must confirm the authenticity of existing inventory due to the end-of-life status. Cross-referencing datasheets is recommended to ensure compatibility with legacy designs requiring this specific package and speed grade.

Complex Programmable Logic Devices Selection Notes

Select this part when a 5V supply is required and Flash-based non-volatility is preferred over EEPROM technologies found in other series. The 15 ns speed grade suits moderate-frequency applications where 5 ns variants are unnecessary. Ensure the PCB footprint accommodates the 44-pin PLCC package. Consider the XC9572XL series if lower 3.3V operation or faster switching speeds are needed for modern replacements.

Complex Programmable Logic Devices Part Context

The XC9572-15PC44C belongs to the original XC9500 family, which established the standard for high-density CPLDs using FastFLASH technology. This series was succeeded by the XC9500XL and XC9500XV families, which introduced 3.3V operation and improved performance metrics. The '15' suffix denotes the 15 ns speed grade, while 'PC44' specifies the plastic leaded chip carrier package with 44 pins.

Complex Programmable Logic Devices Replacement Considerations

Microchip Technology ATF15xxASV series devices offer functional pin-compatible alternatives. Lattice Semiconductor ispMACH 4000XL series provides comparable logic density with updated manufacturing processes. Verify that replacement packages match the 44-pin PLCC form factor and that voltage levels align with the 5V requirement.
