EPM7064LC68-7MM

Complex Programmable Logic Devices Overview

The Altera EPM7064LC68-7MM 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 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 through MultiVolt I/O interface capabilities.

Complex Programmable Logic Devices Feature Summary

• High-performance CPLD based on second-generation MAX architecture with 1,250 usable gates.
• Supports 3.3-V or 5.0-V operation via MultiVolt I/O interface for mixed-voltage systems.
• Features programmable macrocell flip-flops with individual clock, enable, clear, and preset controls.
• Includes configurable expander product-term distribution allowing up to 32 product terms per macrocell.

Complex Programmable Logic Devices Applications

• Replacing complex discrete logic such as PALs, GALs, and pLSI devices.
• Implementing high-density integration of SSI, MSI, and LSI logic functions.
• Designs requiring 100% TTL emulation compatibility.

Complex Programmable Logic Devices Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type and speed grade. Confirm voltage operation requirements against the MultiVolt I/O specifications. Ensure design tools support the MAX 7000 family architecture for compilation and programming.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require 64 macrocells and up to 68 I/O pins within an 84-pin PLCC package. Consider the -7 speed grade if a 6 ns propagation delay and 151.5 MHz counter frequency are sufficient. Evaluate the need for MultiVolt I/O if interfacing with both 3.3-V and 5.0-V logic levels.

Complex Programmable Logic Devices Part Context

This device is part of the MAX 7000 family, which offers logic densities ranging from 600 to 5,000 usable gates. The EPM7064 variant specifically provides a balance of density and I/O count, fitting between the EPM7032 and EPM7096 models in terms of resource availability.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other EPM7064 variants with different speed grades or packages, such as EPM7064LC84-7. Cross-family upgrades may involve MAX 7000E or MAX 7000S devices for enhanced features like ISP or slew-rate control.
