EPM7512AEFC256-12

Complex Programmable Logic Devices Overview

The Altera EPM7512AEFC256-12 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 supply voltage of 3.3V with a maximum frequency of 116.3 MHz and a propagation delay of 7.5 ns. It utilizes an EEPROM storage type and supports In-System Programming (ISP) via JTAG. The component is housed in a 256-pin FineLine BGA package.

Complex Programmable Logic Devices Feature Summary

• 512 Macrocells organized into 32 Logic Array Blocks (LABs)
• Maximum operating frequency of 116.3 MHz
• In-System Programmability (ISP) via IEEE 1149.1 JTAG interface
• EEPROM non-volatile memory technology for configuration retention

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems
• Protocol conversion and bus bridging in communication equipment
• Address decoding and glue logic in embedded systems
• State machine implementation for instrumentation

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'FC' against official datasheets to confirm pinout and thermal characteristics, as standard variants may use 'FI'. Confirm RoHS compliance status, as older MAX 7000A batches may not be compliant. Check for end-of-life or obsolescence notices from Intel/Altera distributors before procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this model when 512 macrocells are required with high I/O density. Ensure the design accommodates the 256-pin FBGA footprint. Compare against EPM7512AEFI256-10 if a slower speed grade (-10 vs -12) suffices for cost reduction. Verify that the 3.3V I/O levels match the target system interfaces.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000A series, which introduced ISP capabilities compared to the earlier MAX 7000S. It shares the same core architecture and gate count as other EPM7512AE variants but differs in package type and speed grade. The MAX 7000A series is widely used for legacy system maintenance and low-power CPLD applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other EPM7512AE variants with different speed grades (e.g., -10, -7) or packages (e.g., PQFP208). Cross-family replacements require retargeting and may involve FPGA alternatives from Intel's Cyclone series.
