EPM7064LC44-12

Complex Programmable Logic Devices Overview

The Altera EPM7064LC44-12 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features 64 macrocells, 1,250 usable gates, and 36 I/O pins housed in a PLCC-44 package. The device operates at a supply voltage of 5 V with a maximum propagation delay of 6 ns and a counter frequency of 151.5 MHz. It utilizes EEPROM technology for non-volatile storage and supports reprogramming up to 100 times.

Complex Programmable Logic Devices Feature Summary

• Contains 64 macrocells organized into 4 logic array blocks (LABs).
• Features 36 user I/O pins within a PLCC-44 package.
• Provides 1,250 usable gates based on second-generation MAX architecture.
• Operates at 5.0 V with a maximum pin-to-pin delay of 6 ns.

Complex Programmable Logic Devices Applications

• General-purpose digital logic implementation.
• Replacement for legacy PAL, GAL, and standard cell logic functions.
• System integration requiring high-density programmable logic.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm that the specific ordering suffix matches the required speed grade (-12) and package type (PLCC-44). Ensure design compatibility with 5 V logic levels prior to procurement.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and 36 I/Os are sufficient for the design requirements. The -12 speed grade indicates a 6 ns delay, suitable for moderate-speed applications. Consider the MAX 7000S series if in-system programming via JTAG is required, as this specific variant lacks built-in ISP circuitry.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000 family, which offers logic densities ranging from 600 to 5,000 usable gates. The EPM7064 represents the mid-range density option within the standard MAX 7000 series, distinct from the enhanced MAX 7000E or in-system programmable MAX 7000S variants.
