EPM7064LC44-10

Complex Programmable Logic Devices Overview

The Altera EPM7064LC44-10 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 up to 36 user I/O pins in a 44-pin Plastic Quad Flat Pack (PQFP) package. The device operates at a supply voltage of 5.0 V and delivers a maximum propagation delay of 10 ns, supporting counter frequencies up to 151.5 MHz. It utilizes CMOS EEPROM technology for non-volatile storage, allowing reprogramming up to 100 times.

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 production batch. Ensure proper handling procedures are followed due to moisture sensitivity classification. Review datasheet revision history for any functional updates prior to integration.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and 36 I/Os are required within a 44-pin footprint. The 10 ns speed grade suits moderate-speed applications. Note that MultiVolt I/O operation is not available in 44-pin packages; verify voltage compatibility with connected 5.0 V logic levels. Consider EPM7064S variants if In-System Programming via JTAG is necessary.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000 family, based on second-generation MAX architecture. It serves as a high-density, high-performance PLD solution bridging the gap between simple GALs and complex FPGAs. The family supports TTL emulation and integrates SSI, MSI, and LSI logic functions efficiently.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other EPM7064 variants with different speed grades (e.g., EPM7064LC44-15). For ISP functionality, consider the EPM7064S series, though pinouts may differ slightly regarding JTAG usage.
