EPM7128AELC84-7

Complex Programmable Logic Devices Overview

The Altera EPM7128AELC84-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000AE family. It features 128 macrocells, 68 I/Os, and 2500 usable gates organized into 8 Logic Array Blocks (LABs). Operating at a supply voltage of 3.0 V to 3.6 V, it delivers a maximum frequency of 192.3 MHz with a propagation delay of 5 ns. The device utilizes EEPROM storage technology and supports in-system programmability via IEEE Std. 1149.1 JTAG. It is housed in an 84-pin PLCC package and operates within a commercial temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Procurement Notes

This component is officially listed as discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or surplus market sources. Ensure compliance with RoHS directives if required, as this specific part number may not meet current environmental standards.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells are sufficient for the design logic. Verify that the 3.3 V supply voltage aligns with system requirements. The PLCC-84 package necessitates appropriate PCB footprint design. Consider the 5 ns delay for timing closure in high-frequency applications up to 192.3 MHz.

Complex Programmable Logic Devices Part Context

Part of the MAX 7000AE series, which extends the standard MAX 7000 architecture with 3.3 V in-system programmability. This series bridges legacy 5 V designs with modern low-voltage systems while maintaining compatibility with existing development tools and programming interfaces.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package and speed grade should be verified against official substitution lists. Alternative families like MAX V offer lower power but different architectures. Cross-reference with Intel/Altera official obsolescence notices for recommended upgrades.
