EPM7128ELC84-7YY

Complex Programmable Logic Devices Overview

The Altera EPM7128ELC84-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000E family. It features 128 macrocells organized into eight logic array blocks and provides up to 68 user I/O pins in an 84-pin PLCC package. The device operates at a supply voltage of 5.0 V with a maximum propagation delay of 7.5 ns and a maximum counter frequency of 125 MHz. It utilizes CMOS EEPROM technology for non-volatile configuration, allowing reprogramming up to 100 times.

Complex Programmable Logic Devices Feature Summary

• MAX 7000E architecture with 128 macrocells and 2,500 usable gates
• 5.0-V operation with MultiVolt I/O interface capability
• Enhanced features including six global output enables and two global clocks
• Programmable slew-rate control and power-saving mode

Complex Programmable Logic Devices Applications

• High-density digital logic integration replacing PALs and GALs
• Mixed-voltage system interfacing between 3.3-V and 5.0-V components
• Complex state machine implementation requiring fast input setup times

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this part number may be discontinued or subject to product change notifications. Confirm that the specific speed grade suffix matches design timing requirements. Ensure compatibility with existing PCB footprints for the 84-pin PLCC package before procurement.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells are sufficient for the design logic density. The -7 speed grade offers a 7.5 ns delay suitable for moderate-speed applications. Consider the MAX 7000S variant if In-System Programming (ISP) via JTAG is required, as the standard MAX 7000E does not include built-in ISP circuitry.

Complex Programmable Logic Devices Part Context

This component is part of the second-generation MAX 7000 family from Altera. It serves as a high-performance, EEPROM-based programmable logic solution. The EPM7128E specifically bridges the gap between lower-density devices like the EPM7096 and higher-density options like the EPM7160E.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include other EPM7128 variants with different speed grades (e.g., -10, -12P). For designs requiring In-System Programming, the EPM7128S series is the functional equivalent with added JTAG capabilities.
