EPM7512AEQC208-12N

Complex Programmable Logic Devices Overview

The EPM7512AEQC208-12N is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family, manufactured by Altera. It features 512 macrocells and 32 Logic Array Blocks (LABs), providing 176 user I/O pins within a 208-pin PQFP package. The device operates on a 3.3 V supply voltage with a maximum operating frequency of 116.3 MHz and a typical propagation delay of 7.5 ns. It utilizes EEPROM technology for non-volatile storage and supports In-System Programmability (ISP) via the IEEE Std. 1149.1 JTAG interface.

Complex Programmable Logic Devices Feature Summary

• 512 Macrocells organized into 32 Logic Array Blocks (LABs)
• In-System Programmability (ISP) compliant with IEEE Std. 1149.1 (JTAG) and IEEE Std. 1532
• Configurable I/O operation supporting 2.5 V or 3.3 V levels
• Advanced pin-locking capability to protect existing designs during reprogramming

Complex Programmable Logic Devices Applications

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

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the device's legacy status. Confirm RoHS compliance requirements, as specific suffixes may indicate lead-free variants. Ensure handling procedures adhere to Moisture Sensitivity Level 3 standards to prevent package damage during assembly. Validate that the 3.3 V power supply specifications align with the target system design constraints.

Complex Programmable Logic Devices Selection Notes

Select this model when a high pin count (176 I/O) and moderate speed (7.5 ns delay) are required in a QFP package. Compare against the EPM7512AEFI256-10 if an FBGA package or higher density is preferred. Consider the EPM7512AETI144-12 for applications requiring fewer I/O pins but a smaller footprint. Ensure the design toolchain supports the MAX 7000A architecture for proper compilation and programming.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000A series, which succeeded the original MAX 7000 family. It offers improved performance and lower power consumption compared to its predecessors while maintaining pin compatibility with certain older devices. The MAX 7000A series was widely adopted for cost-effective programmable logic solutions before being superseded by FPGA technologies.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include the EPM7512AEQC208-12. For functional equivalents with different packages, consider the EPM7512AEFI256-10 (FBGA-256). Cross-family migration to Intel/Altera Cyclone or Arria FPGAs requires significant design adaptation.
