EPM7064BTI100-5

Complex Programmable Logic Devices Overview

The Altera EPM7064BTI100-5 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features an EEPROM-based architecture with 64 macrocells and approximately 1250 usable gates organized into four logic array blocks. The device operates at a maximum frequency of 175.4 MHz with a typical pin-to-pin propagation delay of 5 ns. It supports 5V operation and is housed in a 100-pin PQFP package, providing extensive I/O capabilities for high-density digital logic applications.

• High-performance CMOS technology delivering 5 ns pin-to-pin delays and 175.4 MHz counter speeds.
• Includes programmable security bits to protect proprietary design intellectual property.

Complex Programmable Logic Devices Applications

• Replacement of complex discrete logic gate arrays in industrial control systems.
• Interface bridging between different voltage domains or protocol converters.
• State machine implementation for automated manufacturing equipment.
• Address decoding and bus buffering in embedded computer architectures.

Complex Programmable Logic Devices Procurement Notes

This component is from the legacy MAX 7000 series. Verify current availability status as production may be discontinued or limited. Ensure compatibility with existing PCB footprints and programming tools such as ByteBlaster when sourcing replacements.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring deterministic timing and non-volatile storage within a CPLD form factor. Compare against EPM7064 variants based on required I/O count and package type (PQFP vs PLCC). Confirm that the 5V supply voltage aligns with the system's power rails before integration.

Complex Programmable Logic Devices Part Context

The EPM7064BTI100-5 is part of Altera's second-generation MAX architecture. It serves as a bridge between simple PALs/GALs and modern FPGAs, offering a balance of density, speed, and ease of use for medium-complexity logic designs prevalent in the late 1990s and early 2000s.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible alternatives within the same family include other EPM7064 variants with different speed grades or packages. For modern equivalents, consider Intel/Altera MAX 10 or Cyclone IV families, though these require architectural redesign due to SRAM configuration and lower voltage requirements.
