XC2C256-7TQG144I

Complex Programmable Logic Devices Overview

The XC2C256-7TQG144I is a Flash-based Complex Programmable Logic Device (CPLD) from the Xilinx CoolRunner-II family, manufactured by AMD. It features 256 macrocells and operates at a maximum system clock frequency of 133 MHz, corresponding to a 7.5 ns propagation delay. The device utilizes CMOS technology and is housed in a 144-pin Thin Quad Flat Package (TQFP) with a 0.50 mm pitch. It supports non-volatile Flash configuration, allowing for instant-on functionality without external configuration memory.

Complex Programmable Logic Devices Feature Summary

• 256 Macrocells with high-speed I/O capabilities
• Non-volatile Flash configuration for instant-on operation
• 144-pin TQFP package (20 x 20 mm)
• System clock frequency up to 133 MHz

Complex Programmable Logic Devices Applications

• Address decoding and bus bridging
• Power-on reset generation
• Clock buffering and distribution
• General-purpose logic replacement

Complex Programmable Logic Devices Procurement Notes

Verify the suffix 'I' indicates industrial temperature range specifications. Confirm the '7' speed grade corresponds to the 7.5 ns timing requirement. Ensure the TQG144 package matches the PCB footprint design. Check RoHS compliance status as indicated in the datasheet.

Complex Programmable Logic Devices Selection Notes

Select this component when Flash-based non-volatility is required to eliminate external configuration chips. The 256 macrocell count suits moderate complexity logic functions. The TQFP-144 package is suitable for through-hole or standard surface-mount assembly where pin count exceeds smaller CPLD options.

Complex Programmable Logic Devices Part Context

This part belongs to the AMD (formerly Xilinx) CoolRunner-II series, designed for cost-sensitive applications requiring low power consumption and small form factors. It serves as a drop-in replacement for older GALs and PALs in digital logic designs.

Complex Programmable Logic Devices Replacement Considerations

Compatible variants include other CoolRunner-II devices with similar macrocell counts. Verify pin compatibility if substituting with different package options within the same family.
