XC95144XL-10CS144I

Complex Programmable Logic Devices Overview

The XC95144XL-10CS144I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family. It features 144 macrocells, 3200 usable gates, and 8 Logic Array Blocks (LABs). The device operates at a maximum frequency of 178 MHz with a typical propagation delay of 10 ns. It utilizes non-volatile Flash memory for configuration, allowing in-system programmability. The component supports 3.3V I/O levels with 5V tolerance on input pins. It is housed in a 144-pin CSBGA package and operates within an industrial temperature range of -40°C to +85°C.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this part number may be subject to discontinuation or limited availability. Confirm the specific suffix 'CS144' corresponds to the correct package variant, as datasheets often list 'CSG144'. Check for RoHS compliance status if required by current manufacturing standards. Ensure design files are compatible with legacy programming tools if updating existing hardware.

Complex Programmable Logic Devices Selection Notes

Select this model when 144 macrocells and 10 ns speed are required in a compact BGA footprint. Compare against the TQFP-144 variant if board space allows for larger packages. Ensure the design accounts for the 45 mA operating current. Verify that the 5V tolerant inputs meet the interface requirements of connected peripherals without level shifting.

Complex Programmable Logic Devices Part Context

This component belongs to the XC9500XL series, an evolution of the original XC9500 CPLD line. It offers higher density and lower power consumption compared to its predecessors while maintaining pin-to-pin compatibility with many XC9500 devices. The Flash-based architecture eliminates the need for external configuration PROMs, simplifying PCB design.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other XC95144XL variants with different speed grades or packages, such as XC95144XL-10TQ144. For functional equivalents from other manufacturers, verify gate count, I/O voltage levels, and package dimensions carefully.
