EPM7064STC100-5

Complex Programmable Logic Devices Overview

The Altera EPM7064STC100-5 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000S family. It features an EEPROM-based architecture with 64 macrocells and 68 I/O pins housed in a 100-pin TQFP package. The device supports 5.0-V in-system programmability via JTAG, offering a maximum propagation delay of 5 ns and a counter frequency up to 175.4 MHz. It operates within a commercial temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Feature Summary

• MAX 7000S architecture with 64 macrocells and 4 Logic Array Blocks (LABs)
• 5.0-V In-System Programmability (ISP) using IEEE Std. 1149.1 JTAG interface
• High performance with 5 ns pin-to-pin delay and 175.4 MHz counter speed
• EEPROM non-volatile storage allowing unlimited reprogramming

Complex Programmable Logic Devices Applications

• Protocol conversion and interface bridging in communication systems
• Address decoding and control logic in industrial automation
• State machine implementation for test and measurement equipment
• General-purpose digital logic replacement in embedded systems

Complex Programmable Logic Devices Procurement Notes

This component is part of the legacy MAX 7000 series. Verify current availability status as production may be limited or discontinued. Ensure compatibility with existing design tools and verify that the 5V ISP requirement aligns with system power rails. Check for moisture sensitivity levels if storage conditions are uncontrolled.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and 68 I/Os are required in a 100-pin surface-mount package. The -5 suffix indicates a 5 ns speed grade, suitable for high-frequency applications up to 175.4 MHz. Confirm that the system operates at 5.0V, as this variant is optimized for 5V logic levels compared to 3.3V variants.

Complex Programmable Logic Devices Part Context

The EPM7064STC100-5 is a member of the MAX 7000S family, which introduced In-System Programmability (ISP) to the standard MAX 7000 line. It shares architectural similarities with the EPM7064STC100-10 but offers faster switching speeds (5 ns vs 10 ns). It serves as a drop-in replacement for older GALs or PALs requiring higher density and reprogrammability.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes include the EPM7064STC100-10 (slower speed) or EPM7064STC100-7. For pin-compatible alternatives with different speed grades, consider the EPM7064STC100-15. Verify that any replacement maintains the same 100-TQFP footprint and EEPROM programming requirements.
