EPM7064LC44-15

Complex Programmable Logic Devices Overview

The Altera EPM7064LC44-15 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 36 user I/O pins in a 44-pin PLCC package. The device utilizes CMOS EEPROM technology, allowing for reprogramming up to 100 times. Key electrical parameters include a maximum propagation delay of 6 ns, a maximum operating frequency of 151.5 MHz, and operation at a supply voltage of 5.0 V. It supports industrial temperature ranges from 0°C to +70°C.

Complex Programmable Logic Devices Feature Summary

• EEPROM-based architecture with 64 macrocells and 1,250 usable gates
• High-performance speed grade with 6 ns max propagation delay and 151.5 MHz counter frequency
• 36 I/O pins available in a 44-pin Plastic Leaded Chip Carrier (PLCC) package
• Supports 5.0 V operation with MultiVolt I/O capability (excluding 44-pin packages)

Complex Programmable Logic Devices Applications

• Replacement for PALs, GALs, and standard SSI/MSI logic functions
• Implementation of complex combinational and sequential logic circuits
• System control logic in mixed-voltage environments

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated by specific ordering suffixes. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet to prevent package damage prior to soldering.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and 36 I/Os are required in a 44-pin footprint. The -15 speed grade offers a 6 ns delay suitable for moderate-speed applications. Note that MultiVolt I/O is not supported in the 44-pin package; use higher pin-count variants if 3.3V/5.0V interface compatibility is critical.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000 family, which uses second-generation MAX architecture. It is distinct from the MAX 7000S series, which includes In-System Programmability (ISP) via JTAG. The EPM7064LC44-15 represents the standard non-ISP variant within the high-density 64-macrocell segment.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package and logic density include other speed grades of the EPM7064LC44 series. Cross-family replacements may require schematic redesign due to differences in macrocell architecture and I/O drive capabilities.
