EPM7128EQC160-12

Complex Programmable Logic Devices Overview

The EPM7128EQC160-12 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000E family, manufactured by Altera. It utilizes CMOS EEPROM technology and features 128 macrocells organized into 8 Logic Array Blocks (LABs). The device provides up to 100 user I/O pins and offers approximately 2,500 usable gates. Key electrical parameters include a maximum propagation delay of 7.5 ns, a maximum counter frequency of 125 MHz, and operation at a supply voltage of 5.0 V. It is housed in a 160-pin PQFP package.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated on official documentation. Check for moisture sensitivity handling requirements prior to assembly. Ensure design compatibility with existing 5.0-V power supplies.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and 100 I/O pins are required within a 160-pin PQFP footprint. The 7.5 ns speed grade suits applications needing moderate performance. Consider MAX 7000S variants if In-System Programming (ISP) via JTAG is necessary, as the standard E series lacks this feature.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000 family, representing Altera's second-generation CPLD architecture. It serves as a high-density replacement for discrete logic gates and smaller PLDs like PALs or GALs. The EPM7128E variant specifically enhances the base MAX 7000 with additional clocking and output enable resources.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same density may include other EPM7128 variants with different speed grades or packages. For ISP functionality, consider the EPM7128S series. Verify that any substitute maintains the 5.0-V operating voltage and 160-pin PQFP form factor.
