EPM7128ALC84-7

Complex Programmable Logic Devices Overview

The Altera EPM7128ALC84-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features 128 macrocells, 68 I/O pins, and 2500 usable gates within an 84-pin PLCC package. Operating at a nominal 3.3V supply voltage, it delivers a maximum propagation delay of 5 ns and a top frequency of 192.3 MHz. The device utilizes non-volatile EEPROM technology for configuration storage.

Complex Programmable Logic Devices Feature Summary

• 128 Macrocells organized into 8 Logic Array Blocks (LABs)
• In-system programmability via ISP interface
• EEPROM-based non-volatile memory architecture
• 5 ns maximum pin-to-pin propagation delay

Complex Programmable Logic Devices Applications

• Address decoding in embedded systems
• Bus protocol conversion
• Timing control logic
• Signal processing interfaces

Complex Programmable Logic Devices Procurement Notes

This component is designated as Not Recommended for New Designs (NRND) or End-of-Life by the manufacturer. Verification of current stock availability through authorized distributors is required before procurement planning. Compliance with RoHS standards should be confirmed against specific manufacturing dates due to legacy status.

Complex Programmable Logic Devices Selection Notes

Select this part when 128 macrocells and 68 I/Os are sufficient for the design. Ensure the system operates at 3.3V. For designs requiring higher performance or modern support, consider upgrading to the MAX 10 or Agilex families. Verify that the PLCC-84 footprint matches the PCB layout constraints.

Complex Programmable Logic Devices Part Context

Part of the MAX 7000A series, which introduced 3.3V operation compared to the earlier 5V MAX 7000E/S variants. It shares architectural similarities with the EPM7128AE but offers improved speed grades. The 'LC' suffix indicates the Leadless Ceramic Chip Carrier package type.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements are not available due to the NRND status. Functional equivalents may include Intel/Altera MAX V or MAX 10 CPLDs, though these require schematic and firmware adaptation.
