EPM7032LC44-7

Complex Programmable Logic Devices Overview

The Altera EPM7032LC44-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features 64 macrocells, 600 usable gates, and 36 I/O pins housed in a 44-pin PLCC package. The device operates on a single 5V supply with a voltage range of 4.5V to 5.5V. Key electrical parameters include a maximum propagation delay of 7ns and a maximum operating frequency of 142.9MHz. It utilizes non-volatile EEPROM technology for configuration storage.

Complex Programmable Logic Devices Feature Summary

• Contains 64 macrocells organized into 4 Logic Array Blocks (LABs).
• Non-volatile EEPROM memory allows immediate operation upon power-up without external configuration devices.
• Supports high-speed performance with a minimum propagation delay of 7ns.
• Compatible with standard 5V logic levels.

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems.
• Protocol conversion and interface bridging in communication equipment.
• Address decoding and memory interfacing in embedded systems.
• State machine implementation for automated machinery.

Complex Programmable Logic Devices Procurement Notes

This component is discontinued and no longer manufactured by Intel/Altera. Verification should focus on identifying valid surplus stock or authorized distributors holding remaining inventory. Buyers must confirm the specific speed grade suffix (-7) and package integrity, as availability is limited to secondary markets.

Complex Programmable Logic Devices Selection Notes

Select this part when a 5V supply is required and non-volatile configuration is necessary to simplify board design. Compare against the EPM7032A series if lower voltage (3.3V) operation is needed. Ensure the design fits within the 64 macrocell limit; larger designs may require the EPM7064 or EPM7128 variants.

Complex Programmable Logic Devices Part Context

The EPM7032LC44-7 is part of the legacy MAX 7000 CPLD family, originally developed by Altera before its acquisition by Intel. This series was widely adopted for cost-effective logic integration in the 1990s and early 2000s, serving as a bridge between discrete logic gates and more complex FPGAs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are scarce due to discontinuation. Potential alternatives include the Microchip ATF1502AS series or Lattice ispLSI series, though voltage levels and pinouts may differ. Verify compatibility with existing programming tools and firmware.
