EPM7064BTC44-7

Complex Programmable Logic Devices Overview

The Altera EPM7064BTC44-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000B family. It features 64 macrocells, 1,250 usable gates, and 36 user I/O pins housed in a 44-pin TQFP package. The device operates on a 2.5-V supply voltage with a maximum propagation delay of 3.5 ns and a counter frequency up to 303.0 MHz. It utilizes CMOS EEPROM technology for non-volatile storage and supports In-System Programming (ISP) via an IEEE Std. 1149.1 JTAG interface.

Complex Programmable Logic Devices Feature Summary

• High-performance 2.5-V CMOS EEPROM-based architecture with 3.5-ns pin-to-pin logic delays.
• Advanced 2.5-V In-System Programmability (ISP) compliant with IEEE Std. 1149.1 and IEEE Std. 1532.
• MultiVolt I/O interface allowing compatibility with 3.3-V, 2.5-V, and 1.8-V logic levels.
• Configurable macrocells with up to 32 product terms using shareable and parallel expanders.

Complex Programmable Logic Devices Applications

• Mixed-voltage system integration requiring 2.5-V core logic with 3.3-V or 1.8-V I/O interfaces.
• Industrial control applications utilizing high-density SSI, MSI, and LSI logic functions.
• Communication equipment requiring fast input setup times and predictable timing performance.
• Designs needing reprogrammable logic for field upgrades via ISP capabilities.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Ensure programming hardware supports the specific ISP algorithms required for MAX 7000B devices.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 64 macrocells with a 44-pin footprint. The -7 speed grade provides a 3.5-ns delay suitable for frequencies exceeding 300 MHz. Consider the MultiVolt capability if interfacing with mixed-voltage peripherals. Verify that the design toolchain supports the MAX+PLUS II or Quartus development systems for compilation.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000B series, which serves as a successor to the MAX 7000A family. It offers pin-compatibility with 5.0-V MAX 7000S and 3.3-V MAX 7000A devices in similar packages. The series is characterized by its second-generation Multiple Array MatriX (MAX) architecture and EEPROM-based programmability.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible alternatives within the same package include other EPM7064B speed grades such as EPM7064BTQFP-3N or EPM7064BTQFP-5N. Cross-family migration to MAX 7000A or MAX 7000S devices requires verification of voltage level compatibility and I/O configuration settings.
