EPM7064AEWWC

Complex Programmable Logic Devices Overview

The EPM7064AEWWC is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family, manufactured by Altera. It utilizes an EEPROM-based architecture with 64 macrocells and supports up to 32 I/O pins. The device operates at a supply voltage of 3.3V or 5.0V, featuring pin-to-pin propagation delays as fast as 10 ns. It includes built-in JTAG boundary-scan test circuitry for in-system programming and testing. The component is housed in a 44-pin Wide Plastic Small Outline Package (SOIC-W).

Complex Programmable Logic Devices Feature Summary

• EEPROM-based non-volatile configuration allowing instant power-up operation without external memory.
• Supports both 3.3V and 5.0V VCCIO levels for flexible interface compatibility.
• Built-in IEEE 1149.1 JTAG interface for In-System Programming (ISP) and Boundary-Scan Testing (BST).
• High-density logic structure with 64 macrocells distributed across 4 Logic Array Blocks (LABs).

Complex Programmable Logic Devices Applications

• Address decoding and bus bridging in embedded systems.
• State machine implementation for industrial control logic.
• Protocol conversion between different voltage domains.
• General-purpose digital logic expansion.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'WWC' against official datasheets to confirm package dimensions and tape-and-reel availability. Check for End-of-Life (EOL) status or Last-Time-Buy notices from Intel/Altera distributors. Ensure RoHS compliance documentation matches the manufacturing date code, as older batches may differ.

Complex Programmable Logic Devices Selection Notes

Select this part if a non-volatile CPLD with ISP capability is required for low-to-medium density logic. Compare pin counts and I/O voltage requirements against alternatives like the EPM7064SLC44. Consider the 10 ns delay specification for timing constraints. Verify that the 44-pin W package fits the PCB footprint constraints compared to standard SOIC packages.

Complex Programmable Logic Devices Part Context

The EPM7064AEWWC is part of the MAX 7000A series, an evolution of the original MAX 7000 family. This generation offers improved performance and lower power consumption while maintaining backward compatibility with MAX 7000 design flows. It represents a cost-effective solution for legacy system upgrades or new designs requiring simple, reliable programmable logic.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the specific 'WWC' suffix. Equivalent logic density devices include the EPM7064STC44 or EPM7064SLC44, though package types differ. Cross-family migration to MAX V or MAX 10 requires significant schematic and software redesign.
