Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued. Confirm voltage levels and package integrity before integration into designs requiring legacy CPLD functionality.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 5.0 V ISP capability and JTAG support. Ensure design constraints align with the 6 ns delay specification and 68 available I/O pins within the PLCC-84 footprint.

Complex Programmable Logic Devices Part Context

Part of the Altera MAX 7000S series, which enhances the standard MAX 7000E architecture by adding in-system programmability and boundary-scan test features while maintaining pin compatibility with older generations.

Complex Programmable Logic Devices Replacement Considerations

Consider EPM7128AELC84-7 for 3.3 V operation or EPM7128ELC84-7 for non-ISP 5.0 V requirements. Verify speed grade suffixes (-7 vs -10) match timing constraints.
