Complex Programmable Logic Devices Procurement Notes

This component is listed as End-of-Life (EOL). Verification of current availability requires checking authorized distributors or secondary market suppliers. Ensure compliance with RoHS directives if required by the application, as this specific part number may not meet current environmental standards.

Complex Programmable Logic Devices Selection Notes

Select this device when 128 macrocells are sufficient for the design logic density. The 84-pin PLCC package is suitable for through-hole or surface-mount assembly depending on the PCB layout. Verify that the 5.0 V supply voltage aligns with the system power rails, as it is not pin-compatible with lower voltage variants without level shifting considerations.

Complex Programmable Logic Devices Part Context

The EPM7128ELI84-20 is part of the MAX 7000E series, which offers enhanced features over the standard MAX 7000 family, such as additional global clocks and output enables. It serves as a high-density solution within the legacy CPLD portfolio, preceding the ISP-capable MAX 7000S series.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be limited due to the EOL status. Consider the EPM7128EI84-10 for faster speed grades or the EPM7128SLI84-10 for in-system programmability, though package and feature differences must be evaluated.
