EPM7512AEFC256-7

Complex Programmable Logic Devices Overview

The Altera EPM7512AEFC256-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features 512 macrocells organized into 32 Logic Array Blocks (LABs), providing approximately 10,000 usable gates. The device operates at a supply voltage of 3.3 V with a maximum frequency of 116.3 MHz and a typical propagation delay of 7.5 ns. It utilizes EEPROM technology for non-volatile configuration and is housed in a 256-pin thermally enhanced BGA cavity down package.

Complex Programmable Logic Devices Feature Summary

• 512 Macrocells across 32 LABs for high-density logic implementation
• EEPROM-based non-volatile storage allowing instant-on operation
• Supports In-System Programming (ISP) via JTAG interface
• I/O pins compatible with 2.5V, 3.3V, and 5V logic levels

Complex Programmable Logic Devices Applications

• High-speed interface bridging between different voltage domains
• Address decoding and bus buffering in embedded systems
• State machine implementation for industrial control applications
• Replacement for legacy GAL or PAL devices in existing designs

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000A series, an evolution of the original MAX 7000 line. It shares architectural similarities with the EPM7512B but is distinguished by its specific speed grade (-7) and package variant (FC256). The series is known for its robustness and ease of use in mid-range programmable logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package are limited due to the end-of-life status of many MAX 7000 variants. Designers may consider the EPM7512AEQC208-10N if a PQFP-208 package is acceptable, or evaluate Intel/Altera Cyclone II FPGAs for future-proofing, though these require significant schematic and software redesign.
