EPM3064ATC44-4N

Complex Programmable Logic Devices Overview

The Altera EPM3064ATC44-4N is a Complex Programmable Logic Device (CPLD) belonging to the MAX 3000A family. It features 64 macrocells, 1,250 usable gates, and 34 user I/O pins housed in a 44-pin TQFP package. The device operates at a supply voltage of 3.3 V with a maximum propagation delay of 4.5 ns and a counter frequency of 222.2 MHz. It utilizes CMOS EEPROM technology for non-volatile configuration and supports In-System Programming (ISP) via an IEEE Std. 1149.1 JTAG interface.

Complex Programmable Logic Devices Feature Summary

• MultiVolt I/O interface compatible with 5.0-V, 3.3-V, and 2.5-V logic levels
• In-system programmability (ISP) compliant with IEEE Std. 1149.1 and IEEE Std. 1532
• Built-in boundary-scan test (BST) circuitry for manufacturing verification

Complex Programmable Logic Devices Applications

• PCI Local Bus interface logic
• Mixed-voltage system integration
• Replacement for PALs, GALs, and standard SSI/MSI/LSI logic functions

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this part number may be obsolete or discontinued. Confirm that the -4 speed grade meets specific timing requirements for the target application. Ensure programming hardware supports the enhanced ISP algorithm and Jam STAPL files for reliable field updates.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and 34 I/Os are sufficient for the design. The -4 speed grade offers the fastest performance within the MAX 3000A series. Consider the MultiVolt capability if interfacing with 5V legacy systems while maintaining a 3.3V core. Verify package availability in TQFP-44 format.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 3000A family, which provides low-cost, high-density programmable logic. The EPM3064A variant sits between the EPM3032A and EPM3128A in terms of capacity. The 'TC' suffix indicates the TQFP package type, and '-4N' denotes the -4 speed grade with lead-free/compliant construction.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include EPM3064ATC44-5N, EPM3064ATC44-7N, and EPM3064ATC44-10N, which share the same package and pinout but offer slower speed grades.
