EPM7128AETC144-10

Complex Programmable Logic Devices Overview

The EPM7128AETC144-10 is a Complex Programmable Logic Device (CPLD) from Altera's MAX 7000A family, utilizing second-generation MAX architecture and CMOS EEPROM technology. It integrates 128 macrocells and approximately 2,500 usable gates within a 144-pin TQFP package. The device operates at a supply voltage of 3.3V with a maximum propagation delay of 10ns and a typical operating frequency up to 95.2MHz. It supports In-System Programming (ISP) via IEEE Std. 1149.1 JTAG and includes built-in boundary-scan test circuitry.

Complex Programmable Logic Devices Feature Summary

• 128 Macrocells and 2,500 usable gates based on second-generation MAX architecture
• 3.3V operation with In-System Programmability (ISP) via JTAG interface
• 10ns maximum pin-to-pin propagation delay
• Built-in boundary-scan test (BST) compliant with IEEE Std. 1149.1

Complex Programmable Logic Devices Applications

• Address decoding and bus interfacing in industrial control systems
• Signal processing and timing control for data acquisition modules
• Protocol conversion between TTL/CMOS logic standards

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to the discontinued status of the MAX 7000A series. Confirm that the specific suffix indicates the 144-pin TQFP package and 10ns speed grade. Check for RoHS compliance variations across manufacturing batches, as older stock may not meet current environmental regulations.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells are sufficient for logic density requirements. Ensure the design utilizes 3.3V I/O levels or compatible level shifters. The 144-pin TQFP package requires surface-mount assembly capabilities. Consider the 10ns delay specification against system timing constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000A series, which introduced 3.3V ISP capabilities to the established MAX 7000 platform. It serves as a high-density replacement for lower-capacity PLDs while maintaining compatibility with legacy MAX 7000S designs through pin-compatible options.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include EPM7128AE variants with different speed grades or package types. For modern equivalents, consider Intel MAX 10 or Agilex families, though these require significant architectural redesign.
