EPM7064SLI44-7N

Complex Programmable Logic Devices Overview

The EPM7064SLI44-7N is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family, manufactured by Altera. It features an EEPROM-based architecture with 64 macrocells distributed across four logic array blocks (LABs). The device provides 36 user I/O pins and supports in-system programming (ISP) via a built-in IEEE Std. 1149.1 JTAG interface. Key electrical parameters include a maximum propagation delay of 5 ns, a maximum counter frequency of 175.4 MHz, and operation within a supply voltage range of 3.0 V to 3.6 V. It operates within a commercial temperature range of -40°C to +85°C and is housed in a 44-pin PLCC package.

Complex Programmable Logic Devices Feature Summary

• Prototyping and low-volume production logic circuits

Complex Programmable Logic Devices Procurement Notes

This component is identified as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus market sources. Ensure that any sourced units are genuine Altera products and verify RoHS compliance status, as older batches may differ from current environmental standards.

Complex Programmable Logic Devices Selection Notes

Select this device when 64 macrocells and 36 I/Os are required in a 44-pin surface-mount package. The -7 speed grade offers a 5 ns delay suitable for applications requiring up to 175.4 MHz clock speeds. Consider the MAX 7000S series specifically if JTAG boundary-scan testing and in-system programming capabilities are necessary for the design workflow.

Complex Programmable Logic Devices Part Context

The EPM7064SLI44-7N is part of the MAX 7000S series, which enhances the standard MAX 7000 family with ISP capabilities. It shares architectural similarities with the EPM7064S series but includes specific packaging and speed grade variations. The 'L' indicates a plastic leaded chip carrier package, while 'I' denotes the industrial temperature range.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include other EPM7064S variants with different speed grades or packages, such as EPM7064SLC44-10. For non-pin-compatible upgrades, consider higher-density devices like the EPM7128S, though software adaptation will be required.
