EPM7064LC68-12YY

Complex Programmable Logic Devices Overview

The Altera EPM7064LC68-12YY is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features 64 macrocells organized into four logic array blocks and provides up to 68 user I/O pins in a 68-pin PLCC package. The device utilizes CMOS EEPROM technology for non-volatile configuration, allowing reprogramming up to 100 times. Key electrical parameters include a maximum propagation delay of 12 ns, a maximum counter frequency of 151.5 MHz, and operation within a 3.0 V to 3.6 V supply voltage range.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to the age of the MAX 7000 series. Confirm the specific -12 speed grade and LC68 package variant against the datasheet specifications. Ensure compatibility with existing design tools such as Quartus Prime or legacy MAX+PLUS II software for compilation and programming.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design complexity. The -12 speed grade offers a balance between performance and power consumption. Consider the 68-pin PLCC package constraints for PCB layout. Verify that the 3.0 V to 3.6 V operating voltage aligns with the system power rails.

Complex Programmable Logic Devices Part Context

This part belongs to the Altera MAX 7000 family, which was designed to replace standard PALs, GALs, and complex gate arrays. It uses second-generation MAX architecture with a fixed-delay programmable interconnect array. The family supports both combinatorial and sequential logic functions with high density relative to its era.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package may include other EPM7064 variants with different speed grades (e.g., -15). Cross-family migration to newer Intel/Altera CPLDs requires schematic redesign and toolchain updates.
