EPM7064STC44-5N

Complex Programmable Logic Devices Overview

The Altera EPM7064STC44-5N is a MAX 7000S series Complex Programmable Logic Device (CPLD) housed in a 44-pin Thin Quad Flat Pack (TQFP). It features 64 macrocells organized into four Logic Array Blocks (LABs), providing 1,250 usable gates and 36 user I/O pins. The device operates at a supply voltage of 5.0 V with a maximum propagation delay of 5 ns and a counter frequency of 175.4 MHz. It supports 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

• MAX 7000S architecture with 64 macrocells and 4 LABs
• 5.0-V In-System Programmability (ISP) via JTAG
• 5 ns pin-to-pin delay and 175.4 MHz counter speed
• EEPROM-based non-volatile storage

Complex Programmable Logic Devices Applications

• PCI-compliant logic interfacing
• Gate replacement for PALs, GALs, and PLAs
• Complex state machine implementation
• Bus protocol conversion

Complex Programmable Logic Devices Procurement Notes

Verify the component status as End-of-Life (EOL). Confirm that the TQFP-44 package meets thermal requirements, as the datasheet notes complete thermal analysis is necessary for this package type. Ensure programming hardware supports the specific ISP algorithm required by the device suffix.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 5.0 V operation and JTAG-based ISP. Note that MultiVolt I/O is not available in 44-pin packages; all I/Os are fixed to the device's operating voltage. Compare against EPM7064AE variants if 3.3 V operation or lower power consumption is required.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000 family, representing second-generation MAX architecture. It is distinct from the standard MAX 7000 and MAX 7000A/B families due to its integrated ISP capabilities and specific speed grade (-5). It serves as a high-density solution for legacy logic integration.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements include other EPM7064S speed grades (e.g., -6, -10) if timing permits. For voltage translation, consider the EPM7064AE series, though pin compatibility must be verified per package.
