EPM7064LC84-12

Complex Programmable Logic Devices Overview

The Altera EPM7064LC84-12 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features 1,250 usable gates and 64 macrocells organized into four logic array blocks (LABs). The device provides up to 68 user I/O pins and operates within a voltage range of 3.0 V to 3.6 V. Key electrical parameters include a maximum propagation delay of 12 ns, a setup time of 6 ns, and a maximum counter frequency of 151.5 MHz. It utilizes CMOS EEPROM technology for non-volatile configuration.

• TTL emulation and integration of SSI, MSI, and LSI logic functions
• Replacement for PALs, GALs, and pLSI devices in high-density applications

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 End-of-Life (EOL) notifications or Product Change Notices (PCN) prior to procurement, as availability may be restricted.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and 68 I/O pins are required within an 84-pin PLCC package. Ensure the design operates within the 3.0 V to 3.6 V supply range. Consider the -12 speed grade if a 12 ns maximum propagation delay is acceptable. Verify that MultiVolt I/O capabilities are needed for mixed-voltage system interfacing.

Complex Programmable Logic Devices Part Context

This device is part of the MAX 7000 family, which is based on Altera’s second-generation MAX architecture. The family ranges from 600 to 5,000 usable gates. The EPM7064LC84-12 specifically targets applications requiring moderate density with high performance and flexible I/O configurations.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible low-voltage alternatives exist within the MAX 7000A and MAX 7000B series. Verify functional equivalence regarding gate count, macrocell structure, and timing specifications before substitution.
