EPM570ZM256C7N

Complex Programmable Logic Devices Overview

The EPM570ZM256C7N 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 for configuration and supports In-System Programmability via JTAG. It operates with a single 1.8V supply voltage and offers up to 160 I/O pins in a 256-pin BGA package. The maximum propagation delay is specified at 9 ns, supporting clock frequencies up to 152 MHz.

Complex Programmable Logic Devices Feature Summary

• Non-volatile Flash technology providing instant-on capability without external configuration devices.
• Supports In-System Programmability (ISP) using standard JTAG interface.
• Single 1.8V power supply operation simplifies system design.
• High-density architecture with 570 logic elements and 440 macrocells.

Complex Programmable Logic Devices Applications

• Replacement for complex discrete logic in industrial control systems.
• Address bus decoding and address translation in embedded systems.
• Interface bridging between different voltage domains or protocols.
• State machine implementation for automated machinery.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix '7' against official datasheets, as public records predominantly list variants such as C6N or I8N for this package. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly. Check for any Product Change Notifications regarding label changes or manufacturing site updates from Intel/Altera.

Complex Programmable Logic Devices Selection Notes

Select this component when a single 1.8V supply is available and non-volatile storage is required. Compare the 9 ns delay against timing requirements; faster grades like C4N exist but may differ in pinout or availability. Ensure the 256-BGA footprint matches the PCB layout constraints. Consider the EPM570Z series for lower voltage applications compared to the standard EPM570 which supports 2.5V/3.3V.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX II family, designed to replace complex TTL/CMOS logic. The 'Z' suffix typically denotes the 1.8V variant within the EPM570 line. It serves as a mid-range solution offering more capacity than the EPM240 but less than the EPM1270, balancing cost and performance for moderate complexity designs.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other EPM570Z variants with different temperature ranges or speed grades, such as EPM570ZM256C6N or EPM570ZM256I8N. Verify pin compatibility before substitution. Non-Z variants like EPM570M256C5N require different voltage handling.
