XC2C256-6CPG132C

Complex Programmable Logic Devices Overview

The AMD XC2C256-6CPG132C is a CoolRunner-II Complex Programmable Logic Device (CPLD) manufactured by AMD. It features 256 macrocells, 16 logic blocks, and approximately 6000 usable gates. The device supports system-in-programmability and operates within a junction temperature range of -40°C to +85°C. Key electrical specifications include an internal supply voltage of 1.7V to 1.9V and a maximum propagation delay of 6.7ns. It is housed in a 132-pin CSPBGA package with 106 available I/Os.

• Address decoding and control logic in embedded systems
• State machine implementation for industrial controllers
• Replacement for legacy GAL or PAL devices

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' against official AMD documentation to confirm commercial grade temperature rating versus industrial variants. Confirm RoHS compliance status as per current manufacturing notices. Check for End-of-Life (EOL) announcements from AMD or Xilinx, as older CPLD families may have limited availability or require qualification of alternative sources.

Complex Programmable Logic Devices Selection Notes

Select this component when 256 macrocells are sufficient for the design complexity. Ensure the 132-pin footprint matches the PCB layout constraints. Verify that the 1.7V-1.9V core voltage aligns with the system's power budget and that external level shifters are not required if interfacing with 3.3V logic, as I/O voltages may need configuration.

Complex Programmable Logic Devices Part Context

This part belongs to the CoolRunner-II family, which succeeded the original CoolRunner series. It offers improved density and lower power compared to predecessors while maintaining compatibility with existing development tools like ISE Design Suite. The XC2C256 variant represents a mid-range density option within this specific CPLD portfolio.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be limited due to EOL status. Consider AMD XC2C128 or XC2C384 for similar packages with adjusted capacity. Third-party alternatives from Lattice or Efinix may offer functional equivalents but require schematic and timing verification.
