EPM7064LI44-15

Complex Programmable Logic Devices Overview

The Altera EPM7064LI44-15 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features 64 macrocells, 1250 usable gates, and 36 user I/O pins housed in a 44-pin PLCC package. The device 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 5.0-V operation.

Complex Programmable Logic Devices Feature Summary

• 64 Macrocells organized into 4 Logic Array Blocks (LABs)
• Maximum operating frequency of 151.5 MHz
• Pin-to-pin logic delay of 6 ns
• CMOS EEPROM fabrication process

Complex Programmable Logic Devices Applications

• General-purpose digital logic implementation

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix corresponds to the required speed grade and package variant. Ensure compliance with applicable environmental regulations relevant to the procurement region.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and 36 I/Os are sufficient for the design requirements. The -15 speed grade provides a 6 ns delay suitable for moderate-speed applications. Consider the MAX 7000S series if In-System Programming (ISP) via JTAG is required, as this specific part number does not indicate ISP capability.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000 family, which represents second-generation CPLD architecture. It serves as a high-density, high-performance alternative to traditional programmable logic devices, offering reprogrammability and integration capabilities for complex digital systems.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include other EPM7064 variants with different speed grades or packages. Cross-family replacements may require schematic modifications due to differences in macrocell architecture and I/O configurations.
