EPM7064AETC44-10

Complex Programmable Logic Devices Overview

The Altera EPM7064AETC44-10 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 operates at a supply voltage of 3.3 V (range 3.0 V to 3.6 V) with a maximum propagation delay of 4.5 ns and a maximum frequency of 222.2 MHz. It utilizes EEPROM technology for non-volatile storage and is housed in a 44-pin TQFP package. The component supports an operating temperature range of 0°C to +70°C.

• Address decoding and bus interfacing
• State machine control
• Protocol conversion

Complex Programmable Logic Devices Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct distribution channels. Confirm RoHS compliance status, as original specifications may indicate non-compliance depending on production date. Validate package integrity and pin condition upon receipt.

Complex Programmable Logic Devices Selection Notes

Select this part when 64 macrocells are sufficient for the design logic. Ensure the application requires 3.3 V logic levels. The TQFP-44 package limits I/O count to 36; designs requiring more pins must consider larger packages like the TC100 variant. Verify that the 4.5 ns delay meets timing constraints for the target clock frequency.

Complex Programmable Logic Devices Part Context

The EPM7064AETC44-10 is part of the Intel (formerly Altera) MAX 7000 series, known for high-density CPLDs using EEPROM technology. This specific suffix denotes the 10 ns speed grade (actual 4.5 ns delay), AEC automotive qualification (if applicable per datasheet, though often standard commercial), and the 44-pin Thin Quad Flat Package (TQFP). It succeeded earlier PLD technologies by offering reprogrammability without UV erasure.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include the EPM7064STC44-15 (slower speed, different suffix code). For higher performance, the EPM7064AETC44-10N may be considered if available. Cross-family migration to MAX V or MAX 10 requires significant redesign due to architectural differences.
