EPM570F256C5N

Complex Programmable Logic Devices Overview

The EPM570F256C5N is a Complex Programmable Logic Device (CPLD) belonging to the MAX II family, manufactured by Altera. It features 570 logic elements and 440 macrocells within 57 Logic Array Blocks (LABs). The device utilizes non-volatile Flash memory technology for instant-on operation. It supports System In-Programmability (SIP) and operates with internal supply voltages of 2.5V and 3.3V. The component provides 160 I/O pins and is housed in a 256-BGA package with dimensions of 17x17 mm. The maximum propagation delay is specified at 5.4 ns, and it functions within a junction temperature range of 0°C to 85°C.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C5N' against the manufacturer's current datasheet to confirm pinout compatibility and electrical characteristics. Check for Product Change Notices (PCNs) regarding label changes or manufacturing site transfers, as historical records indicate PCNs related to device labeling for this series. Ensure the 256-FBGA package handling requirements align with assembly capabilities.

Complex Programmable Logic Devices Selection Notes

Select this model when 440 macrocells and 160 I/Os are required in a BGA footprint. Compare against the EPM570ZM256C6N if lower speed (9 ns delay) but potentially different power profiles are acceptable. Verify that the 1.8V I/O capability of other MAX II variants is not strictly necessary, as this specific part specifies 2.5V/3.3V internal supplies. Confirm that the 5.4 ns delay meets the timing constraints of the target design.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX II family, which succeeded earlier CPLD lines by integrating Flash memory to eliminate the need for external configuration devices. The EPM570 variant represents a mid-range density option within this family, offering a balance between logic capacity and pin count. It is designed for cost-sensitive applications requiring non-volatile programmability.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes within the same package and pinout include other EPM570F256 variants with different speed grades or temperature ranges, such as EPM570F256C3N, provided timing specifications allow. Cross-family replacements require re-evaluation of logic resources and I/O configurations.
