XC95144XV-7TQ144I

Overview

The XC95144XV-7TQ144I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, designed for 3.3V low-voltage systems. It features 144 macrocells and approximately 3,200 usable gates distributed across eight Function Blocks. The device operates within a commercial temperature range of 0°C to +70°C and utilizes a 144-pin TQFP package. Key electrical specifications include a maximum propagation delay of 7 ns and a maximum operating frequency of 178 MHz. It supports in-system programming via JTAG and offers 5V-tolerant I/O capabilities.

Feature Summary

• 144 Macrocells with 8 Function Blocks providing high logic density
• FastCONNECT II switch matrix architecture for efficient routing
• In-System Programmability (ISP) via IEEE 1149.1 JTAG interface
• 5V tolerant inputs compatible with mixed voltage environments

Applications

• System control and glue-logic replacement
• I/O buffering and level shifting
• State machine implementation
• Bus bridging and interface protocol front-ends

Procurement Notes

Verify component authenticity as this part number may be subject to discontinuation or limited availability. Confirm that the 'XV' suffix denotes the specific speed grade and temperature rating required for your application design. Ensure ESD protection protocols are followed during handling due to the CMOS technology used in the XC9500XL series.

Selection Notes

Select this model when a 7 ns speed grade is required for designs operating up to 178 MHz. The TQFP-144 package is suitable for surface-mount applications requiring a moderate pin count. Consider the 5V tolerance feature if interfacing with legacy 5V peripherals without additional level shifters. Verify power supply requirements for VCCINT and VCCIO domains before finalizing the schematic.

Part Context

This component belongs to the XC9500XL High Performance CPLD family, which succeeded the original XC9500 series. The XC9500XL line introduced Flash memory technology for non-volatile configuration, eliminating the need for external PROMs. The XC95144 variant specifically targets applications needing higher logic capacity than the 64-macrocell devices while maintaining compatibility with existing XC9500 design tools and methodologies.

Replacement Considerations

Direct replacements include other variants within the XC95144XL family such as XC95144XL-7TQ144I or XC95144XL-10TQ144I, depending on timing requirements. Cross-family migration to the XC9500 series may require retiming analysis but preserves logical functionality. Always verify pinout compatibility between different package options like CSBGA or PQFP.
