EPM570F256C4N

Complex Programmable Logic Devices Overview

The EPM570F256C4N is a Complex Programmable Logic Device (CPLD) belonging to the Altera MAX II family. It features 570 logic elements and 440 macrocells, housed in a 256-pin FineLine BGA package measuring 17x17 mm. The device supports system-in-system programming and operates with internal supply voltages of 2.5V and 3.3V. Key electrical specifications include a maximum propagation delay of 5.4 ns and a maximum operating frequency of 304 MHz. It functions within a junction temperature range of 0°C to 85°C and utilizes Flash memory for non-volatile configuration storage.

• Supports In-System Programming (ISP) for flexible field updates.
• Utilizes non-volatile Flash technology, eliminating the need for external configuration memory.
• Provides 160 I/O pins with flexible pinout assignments.

Complex Programmable Logic Devices Applications

• Interface bridging between different voltage domains or protocol converters.
• Address decoding and chip select generation in embedded systems.
• State machine implementation for control logic applications.
• Replacement for legacy GAL or PAL devices in industrial equipment.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C4N' against the manufacturer's current ordering guide to confirm package dimensions and lead times. Check for Product Change Notices (PCNs) regarding label changes or material updates. Confirm RoHS compliance status and Moisture Sensitivity Level (MSL 3) requirements for surface-mount assembly processes.

Complex Programmable Logic Devices Selection Notes

Select this model when 440 macrocells and 160 I/Os are required in a 256-ball BGA footprint. Ensure the design voltage aligns with the 2.5V/3.3V internal supply capabilities. Compare against EPM570T144C5N if a TQFP package is preferred, or EPM570GF100C5N if lower power consumption at 1.8V is critical, noting that I/O counts will differ significantly.

Complex Programmable Logic Devices Part Context

This component is part of the MAX II family, designed as a low-cost, high-density alternative to traditional CPLDs. It succeeded earlier MAX families by integrating Flash memory directly on-chip. The F256 variant specifically targets designs requiring high I/O density in a compact surface-mount form factor, serving as a bridge between simple logic gates and larger FPGAs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package are limited due to specific suffix variations. Verify compatibility with EPM570F256 variants having different speed grades or temperature ranges. Cross-family migration to MAX V or MAX 10 requires retiming and resource verification.
