EPM7128AFC100-6

Complex Programmable Logic Devices Overview

The Altera EPM7128AFC100-6 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It utilizes second-generation MAX architecture with CMOS EEPROM technology, providing 128 macrocells and approximately 2,500 usable gates. The device operates at a supply voltage of 3.3V and features an extended industrial temperature range from -40°C to +85°C. Packaged in a 100-pin FineLine BGA (FBGA), it supports In-System Programming (ISP) via IEEE Std. 1149.1 JTAG interface. Key electrical parameters include a maximum operating frequency of 147.1 MHz and a pin-to-pin propagation delay of 6 ns.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels. Confirm RoHS compliance status as some legacy variants may not meet current environmental standards. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly. Ensure design files are compatible with supported development tools such as Quartus II.

Complex Programmable Logic Devices Selection Notes

Select this model when 3.3V logic compatibility and industrial temperature stability are required. The FBGA package suits applications needing high I/O density in compact footprints. Compare against MAX 7000S series if 5V tolerance is necessary, noting that the A series is optimized for lower voltage operations.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000A family, which succeeded the MAX 7000S series by introducing native 3.3V operation while maintaining pin compatibility with many 5V devices. The EPM7128 variant represents a mid-density solution within the CPLD portfolio, balancing performance and resource availability for general-purpose logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include other EPM7128A speed grades (e.g., EPM7128AFC100-10). Cross-family migration to newer Intel/Altera CPLDs requires schematic and code adaptation due to architectural differences.
