EPM570F256C5

Complex Programmable Logic Devices Overview

The Altera EPM570F256C5 is a Complex Programmable Logic Device (CPLD) belonging to the MAX II family. It features 570 logic elements and 440 macrocells, housed in a 256-pin FineLine BGA package. The device supports system-in-system programming and utilizes non-volatile Flash memory for configuration. Electrical specifications include a maximum propagation delay of 5.4 ns and operation at supply voltages of 2.5V or 3.3V. The component is designed for surface-mount installation with a commercial operating temperature range.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash technology enabling instant-on functionality
• Supports In-System Programming (ISP) for flexible field updates
• 256-pin FineLine BGA package with 160 available I/O pins

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems
• Address decoding and bus bridging in computer and storage equipment
• Interface translation in telecommunications infrastructure
• Test and measurement instrument logic control

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix designation against official datasheets, as variations such as C5N indicate specific pin pitch or lead finish options. Confirm RoHS compliance status and humidity sensitivity level prior to procurement. Ensure the supplier provides traceability documentation matching the manufacturer's part number format to avoid counterfeit components.

Complex Programmable Logic Devices Selection Notes

Select this model when 570 logic resources are required within a 256-pin footprint. Compare against EPM570T144C5N if a smaller TQFP package is preferred despite reduced I/O count. Verify that the target application voltage aligns with the 2.5V or 3.3V internal supply requirements. Check PCB layout constraints for the 17x17mm FBGA body size.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX II series, which succeeded earlier MAX VII families. It represents a transition to lower voltage operation while maintaining high density. The F256 designation specifically identifies the 256-pin FineLine BGA package variant within the broader EPM570 product line.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements may include other MAX II devices with identical pin counts but different logic densities. Verify electrical characteristics match before substituting. No direct cross-manufacturer equivalents exist due to proprietary CPLD architecture.
