XA2C256-8VQG100Q

Complex Programmable Logic Devices Overview

The XA2C256-8VQG100Q is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC2000XA family. It features 256 macrocells and operates at a maximum system clock frequency of 83 MHz in the -8 speed grade. The device utilizes a 1.8V core voltage with I/O voltages supporting 1.8V, 2.5V, or 3.3V levels. It is housed in a 100-pin VQFP package with a 14x14mm body size. This component provides non-volatile configuration storage and supports standard JTAG programming interfaces for design implementation.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'Q' indicates qualified reliability standards if required by your application. Confirm the -8 speed grade meets timing requirements. Check current lifecycle status as older CPLD families may face obsolescence. Ensure ESD protection measures are followed during handling due to CMOS technology sensitivity.

Complex Programmable Logic Devices Selection Notes

Select this part when 256 macrocells are sufficient for the logic density needs. The -8 speed grade offers a balance of performance and power. Consider the VQFP package constraints for PCB layout. Verify that the 1.8V core voltage aligns with the target system's power supply architecture. Compare against higher-density XC9500 series if more macrocells are eventually required.

Complex Programmable Logic Devices Part Context

This component belongs to the XC2000XA family, an evolution of the original XC2000 CPLD line. It shares architectural similarities with the XC9500 series but uses a different process node and feature set. The XA variant typically denotes enhanced non-volatile configuration capabilities compared to earlier volatile versions.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package and logic density should be sought from the XC2000XA series. Higher speed grades like -10 or -12 offer faster performance but may require verification of power and thermal limits. Cross-family migration to XC9500XL requires schematic redesign due to architectural differences.
