EPM7512AEBC256-12

Complex Programmable Logic Devices Overview

The Altera EPM7512AEBC256-12 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features 512 macrocells, 32 Logic Array Blocks (LABs), and approximately 10,000 usable gates. The device operates at a maximum frequency of 94.3 MHz with a typical propagation delay of 12 ns. It utilizes an EEPROM storage type and supports in-system programmability via JTAG. The component is housed in a 256-pin thermally enhanced BGA cavity down package, providing up to 212 user I/O pins.

Complex Programmable Logic Devices Feature Summary

• 512 Macrocells organized into 32 Logic Array Blocks (LABs)
• EEPROM-based non-volatile memory technology
• Supports In-System Programmability (ISP) through IEEE Std. 1149.1 JTAG interface
• Operates on a single 3.3 V supply voltage

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems
• Address decoding and bus bridging in communication equipment
• State machine implementation for instrumentation
• General-purpose digital logic integration

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-12) against current manufacturer documentation, as availability may vary. Confirm that the 256-pin BGA cavity down package matches the target PCB footprint requirements. Check for RoHS compliance status, as older EEPROM CPLDs may have restricted material declarations depending on the manufacturing date code.

Complex Programmable Logic Devices Selection Notes

Select this model when 512 macrocells are required with a 12 ns speed grade. Ensure the design accommodates the 256-pin BGA cavity down package constraints. Compare against the EPM7512B series if 2.5 V operation is necessary, as the AE series is optimized for 3.3 V applications. Verify I/O voltage compatibility with connected peripherals.

Complex Programmable Logic Devices Part Context

This device is part of the MAX 7000A family, which succeeded the MAX 7000S and MAX 7000E families. It shares architectural similarities with other high-density devices like the EPM7512AEFI256-10N but offers different pin counts and package options. The family is known for its robust ISP capabilities and CMOS EEPROM process technology.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same density include other variants of the EPM7512AE or EPM7512B families with different speed grades or packages. Cross-family migration to newer Intel/Altera CPLD families requires schematic and timing verification.
