EPM3064ATC100-4N

Complex Programmable Logic Devices Overview

The Altera EPM3064ATC100-4N is a CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family. It features 1,250 usable gates, 64 macrocells organized into four Logic Array Blocks (LABs), and 66 user I/O pins in a 100-pin TQFP package. The device operates at a 3.3-V supply voltage with a maximum pin-to-pin propagation delay of 4.5 ns and a counter frequency of 222.2 MHz. It supports In-System Programming (ISP) via IEEE Std. 1149.1 JTAG and includes MultiVolt I/O compatibility for 5.0-V, 3.3-V, and 2.5-V logic levels.

Complex Programmable Logic Devices Feature Summary

• High-performance 4.5-ns pin-to-pin delay with 222.2 MHz counter speed

• MultiVolt I/O interface supporting 5.0-V, 3.3-V, and 2.5-V logic levels
• Programmable interconnect array (PIA) for predictable routing delays

Complex Programmable Logic Devices Applications

• PCI Local Bus Specification Revision 2.2 compatible designs
• Transistor-to-transistor logic (TTL) emulation
• Mixed-voltage system integration
• Small-scale to large-scale integration logic functions

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for moisture sensitivity handling requirements during storage and assembly. Ensure programming hardware compatibility with IEEE 1532 standards for in-system programming operations.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 64 macrocells and 66 I/O pins within a 100-pin TQFP footprint. The -4 speed grade provides 4.5 ns delay suitable for PCI-compliant timing. Consider power-saving modes if energy efficiency is critical, as macrocells can reduce power by over 50%. Verify that the design fits within the 1,250 usable gate limit and utilizes the PIA architecture for optimal routability.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 3000A family, which offers low-cost, high-performance programmable logic solutions. The EPM3064A variant sits between the EPM3032A and EPM3128A in terms of density. It replaces older GAL and PAL devices while maintaining compatibility with legacy design flows through standard development tools like Quartus II.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other speed grades of the EPM3064A series such as EPM3064ATC100-5N or EPM3064ATC100-10N, provided timing constraints allow. Cross-family upgrades may involve EPM3128A for higher density, though pin counts and package types must be evaluated for mechanical compatibility.
