EPM7064STC44-6

Complex Programmable Logic Devices Overview

The Altera EPM7064STC44-6 is a MAX 7000S series Complex Programmable Logic Device (CPLD) housed in a 44-pin Thin Quad Flat Pack (TQFP). It contains 64 macrocells organized into four Logic Array Blocks (LABs) and provides 36 user I/O pins. The device operates at a maximum frequency of 175.4 MHz with a typical pin-to-pin propagation delay of 5 ns. It supports 5.0-V In-System Programming (ISP) via an IEEE 1149.1 JTAG interface and utilizes CMOS EEPROM technology for non-volatile configuration.

Complex Programmable Logic Devices Feature Summary

• Supports 5.0-V In-System Programming (ISP) through a built-in JTAG interface compatible with IEEE Std. 1149.1 and IEEE Std. 1532.
• Features 64 macrocells distributed across four Logic Array Blocks (LABs) with up to 32 product terms per macrocell via parallel expanders.
• Provides fast input setup times (2.5 ns) using dedicated paths from I/O pins to macrocell registers, bypassing the programmable interconnect array.
• Includes open-drain output options and programmable slew-rate control to minimize noise transients.

Complex Programmable Logic Devices Applications

• PCI-compliant logic interfacing
• Gate replacement for PALs, GALs, and standard logic families
• In-system programmable state machines

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this part is end-of-life. Confirm package integrity and pin alignment for the TQFP-44 form factor. Ensure programming equipment supports the specific ISP algorithms required for MAX 7000S devices.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 5.0-V operation and 36 I/O pins in a compact 44-pin surface-mount package. Consider speed grades -5, -6, or -7 based on timing requirements, noting that the -6 grade offers a 5 ns delay. Verify that 3.3-V MultiVolt I/O is not required, as it is unavailable in 44-pin packages.

Complex Programmable Logic Devices Part Context

This device belongs to the MAX 7000S family, which enhances the standard MAX 7000 architecture with ISP capabilities. It shares architectural similarities with the EPM7064S series but is distinguished by its specific speed grade and package type within the broader Altera CPLD portfolio.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other speed grades within the same package, such as EPM7064STC44-5N or EPM7064STC44-7N. Cross-family migration may require redesign due to differences in I/O counts and voltage levels.
