EPM570GT144C5

Complex Programmable Logic Devices Overview

The Altera EPM570GT144C5 is a Complex Programmable Logic Device (CPLD) belonging to the MAX II family. It features 570 logic elements and 440 macrocells, housed in a 144-pin Thin Quad Flat Package (TQFP). The device operates with an internal supply voltage ranging from 1.71V to 1.89V and supports system-in-programmability via JTAG. Key electrical specifications include a maximum propagation delay of 5.4 ns and a maximum operating frequency of 304 MHz. It utilizes non-volatile Flash memory for configuration storage.

Complex Programmable Logic Devices Feature Summary

• Contains 570 logic elements organized into 57 Logic Array Blocks (LABs) and 440 macrocells.
• Supports System-In-Programmability (SIP) using IEEE 1149.1 JTAG interface.
• Features 116 general-purpose I/O pins with flexible pinout assignments.
• Utilizes Flash technology for non-volatile configuration retention without external memory.

Complex Programmable Logic Devices Applications

• Logic replacement for legacy TTL/CMOS circuits in industrial control systems.
• Address bus expansion and data buffering in embedded computer architectures.
• Protocol conversion interfaces between different communication standards.
• State machine implementation for test and measurement equipment.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'G' against official Intel/Altera documentation to confirm package type and temperature grade. Ensure compatibility with Quartus Prime software versions supporting the MAX II family. Confirm RoHS compliance status through the manufacturer's current product change notices or datasheets prior to procurement.

Complex Programmable Logic Devices Selection Notes

Select this component when design requirements fit within 570 logic elements and 116 I/Os. The TQFP-144 package is suitable for surface-mount assembly with standard PCB footprint guidelines. Consider the 5.4 ns delay specification for timing closure in synchronous designs. Verify that the target application environment falls within the commercial temperature range if the 'C' suffix denotes commercial grade.

Complex Programmable Logic Devices Part Context

The EPM570GT144C5 is part of the MAX II family, which succeeded earlier CPLD lines like the MAX 7000 series. This family introduced Flash-based configuration, eliminating the need for external configuration devices. The MAX II series is designed for low-cost, low-power applications requiring moderate logic density and high reliability.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same package and pinout may include other variants in the EPM570 series such as EPM570T144C5N or EPM570GT144I5N, depending on required temperature ranges. Cross-family upgrades to MAX V or MAX 10 require significant schematic and firmware modifications due to architectural differences.
