EPM7064AELC44-4

Complex Programmable Logic Devices Overview

The Altera EPM7064AELC44-4 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features 64 macrocells, 36 I/O pins, and 1250 usable gates within four Logic Array Blocks (LABs). The device utilizes EEPROM technology for non-volatile configuration and operates at a supply voltage of 3.3 V (range 3.0 V to 3.6 V). Key electrical parameters include a maximum operating frequency of 222.2 MHz, a maximum propagation delay of 4.5 ns, and an industrial temperature range of 0°C to +70°C. It is housed in a PLCC-44 surface-mount package.

Complex Programmable Logic Devices Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Verification of authenticity is critical due to potential availability from third-party distributors. Check RoHS compliance status, as indicated data shows 'N' for some listings, which may conflict with modern regulatory requirements. Confirm package integrity and pin condition upon receipt.

Complex Programmable Logic Devices Selection Notes

Select this part when a low-pin-count CPLD with EEPROM persistence is required. Compare against EPM7064AE variants with different speed grades or packages if timing constraints differ. Ensure the design fits within the 64 macrocell limit and 36 I/O constraint. Verify that 3.3 V logic levels are compatible with the target system interfaces.

Complex Programmable Logic Devices Part Context

The EPM7064AELC44-4 is part of the Altera MAX 7000S series, designed for cost-sensitive applications requiring moderate logic density. It succeeded earlier GAL replacements and offers reprogrammability via standard ISP tools. The 'LC' suffix denotes the PLCC-44 package, while '-4' indicates the fastest speed grade in this specific package variant.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements may be limited due to EOL status. Consider EPM7064AE variants with different speed grades (e.g., -10, -15) if timing allows, though they may have different packaging. Cross-reference with Intel/Altera's current CPLD portfolios for long-term supply stability.
