EPM7064LC68-12MM

Complex Programmable Logic Devices Overview

The Altera EPM7064LC68-12MM 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. The device supports up to 68 user I/O pins and operates at a maximum frequency of 151.5 MHz with a typical pin-to-pin propagation delay of 6 ns. It utilizes CMOS EEPROM technology for non-volatile configuration and supports 3.3-V or 5.0-V operation.

Complex Programmable Logic Devices Feature Summary

• High-performance CPLD based on second-generation MAX architecture with 1,250 usable gates.
• 64 macrocells distributed across 4 logic array blocks (LABs).
• Supports up to 68 user I/O pins in PLCC-68 package.
• Maximum counter frequency of 151.5 MHz with 6 ns typical pin-to-pin delay.

Complex Programmable Logic Devices Applications

• General-purpose digital logic implementation replacing PALs, GALs, and standard SSI/MSI components.
• Bus interface bridging between different voltage domains using MultiVolt I/O capability.
• State machine and control logic design requiring reprogrammable EEPROM storage.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-12MM) against official datasheet Table 3 to confirm availability and exact timing parameters. Confirm package type matches PLCC-68 requirements. Check for end-of-life status as older MAX 7000 variants may be discontinued.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require 64 macrocells and high-density integration. Ensure voltage levels match the 3.3-V or 5.0-V operating range. Consider the -12 speed grade if 6 ns delay is acceptable; faster grades like -5 or -6 offer lower delays but may have different package availability.

Complex Programmable Logic Devices Part Context

Part of the MAX 7000 family, which offers 600 to 5,000 usable gates. This series bridges the gap between simple PLDs and complex FPGAs, providing deterministic timing via a fixed-delay programmable interconnect array (PIA).

Complex Programmable Logic Devices Replacement Considerations

Check for MAX 7000E or MAX 7000S variants for enhanced features like JTAG boundary-scan or ISP. Verify pin compatibility with low-voltage MAX 7000A/B devices if migrating to newer process nodes.
