EPM7128SQC160-7

Complex Programmable Logic Devices Overview

The Altera EPM7128SQC160-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family. It features 128 macrocells, 2,500 usable gates, and up to 100 user I/O pins housed in a 160-pin PQFP package. Operating at a 5.0 V supply voltage, this -7 speed grade device offers a maximum propagation delay of 6 ns and a counter frequency of 147.1 MHz. Key architectural elements include eight logic array blocks, EEPROM-based non-volatile storage, and support for in-system programming via JTAG.

Complex Programmable Logic Devices Feature Summary

• In-system programmability (ISP) via IEEE Std. 1149.1 JTAG interface
• Built-in boundary-scan test (BST) circuitry compliant with IEEE Std. 1149.1
• EEPROM technology allowing reprogramming up to 100 times
• MultiVolt I/O interface supporting 3.3-V or 5.0-V operation

Complex Programmable Logic Devices Applications

• PCI-compliant system designs
• Mixed-voltage digital logic integration
• High-density SSI, MSI, and LSI logic replacement
• Industrial control systems requiring field reprogrammability

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix corresponds to the required speed grade (-7) and package type (PQFP-160). Ensure compliance with relevant environmental standards such as RoHS if applicable to the procurement region.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and 100 I/Os are required within a 160-pin footprint. The -7 speed grade provides a 6 ns delay suitable for moderate-speed applications. Consider the MAX 7000E variant if ISP functionality is not needed, or the MAX 7000A/B families for lower voltage requirements.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000S series, which extends the standard MAX 7000E architecture by adding JTAG-based in-system programming capabilities. It shares the same core logic structure but includes dedicated ISP circuitry and BST registers, making it suitable for modern manufacturing workflows requiring post-assembly configuration.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same density include other MAX 7000S devices with different speed grades or packages, such as EPM7128SQI100 or EPM7128SLI84. Verify that the substitute maintains the 5.0 V operating voltage and EEPROM storage characteristics.
