EPM7064LC68-12

Complex Programmable Logic Devices Overview

The Altera EPM7064LC68-12 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features 64 macrocells, 1,250 usable gates, and 68 user I/O pins housed in an 84-pin PLCC package. The device operates at a maximum frequency of 151.5 MHz with a typical pin-to-pin propagation delay of 12 ns. It utilizes CMOS EEPROM technology for non-volatile configuration and supports 5.0-V operation.

Complex Programmable Logic Devices Feature Summary

• 64 Macrocells organized into 4 Logic Array Blocks (LABs)
• 1,250 usable gates with up to 32 product terms per macrocell
• 68 User I/O pins in an 84-pin PLCC package
• 151.5 MHz maximum counter frequency

Complex Programmable Logic Devices Applications

• PCI-compliant logic interface design
• TTL emulation and legacy logic replacement
• High-density SSI, MSI, and LSI integration

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers. Confirm RoHS compliance status as original specifications may vary by manufacturing date. Ensure proper handling procedures are followed due to potential moisture sensitivity classification associated with the plastic leaded chip carrier package type.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and 68 I/Os are required within an 84-pin footprint. The -12 speed grade provides a 12 ns delay suitable for moderate-speed applications. Consider the EPM7064S variant if In-System Programming via JTAG is necessary, as standard MAX 7000 devices lack this feature.

Complex Programmable Logic Devices Part Context

Part of the second-generation MAX architecture family designed for high-density programmable logic. The MAX 7000 series bridges the gap between simple PLDs and FPGAs, offering reprogrammability with fixed-delay interconnects for predictable timing performance across various industrial and commercial temperature ranges.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other MAX 7000 variants such as EPM7064LC68-15 or EPM7064LC68-10. For ISP functionality, consider the EPM7064S series. Verify voltage levels and package dimensions before substitution.
