XC2C256-7VQ100I

Complex Programmable Logic Devices Overview

The XC2C256-7VQ100I is a CoolRunner-II CPLD manufactured by AMD, featuring 256 macrocells and 16 logic blocks within a 100-pin VQFP package. It operates at a maximum propagation delay of 7 ns and supports system-in-system programming. The device functions on an internal supply voltage ranging from 1.7V to 1.9V and is rated for industrial temperatures between -40°C and +85°C. This component belongs to the XC2C256 family, which utilizes a non-volatile flash technology for configuration retention.

Complex Programmable Logic Devices Applications

• Interface bridging in industrial control systems
• Address decoding and bus arbitration
• Simple state machine implementation
• Logic replacement for discrete gates

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm package type is VQFP (14x20mm). Check current availability status as older CPLD families may have limited stock or end-of-life notices from AMD.

Complex Programmable Logic Devices Selection Notes

Select this part when 256 macrocells are sufficient for the design logic. Ensure the 100-pin VQFP footprint matches the PCB layout. Verify that the 1.8V core voltage aligns with the target system's power rails. Consider the 7ns speed grade if timing constraints require faster switching than the slower variants offer.

Complex Programmable Logic Devices Part Context

This component is part of the AMD CoolRunner-II CPLD family, designed for low-power, high-density programmable logic applications. The XC2C256 variant offers a balance of logic density and I/O count suitable for mid-range complexity designs. It serves as a successor to earlier Xilinx CPLD generations, offering improved performance and lower power consumption.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to proprietary architecture. Potential alternatives include Lattice Semiconductor MACH XO2 or Efinix Trident series, but these require schematic and firmware redesign. Verify compatibility with existing programming tools and bitstream formats.
