EPM3064ATC100-7N

Complex Programmable Logic Devices Overview

The Altera EPM3064ATC100-7N is a CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family. It provides 1,250 usable gates and 64 macrocells organized into four logic array blocks. The device operates at a 3.3-V supply voltage with a maximum pin-to-pin propagation delay of 7 ns and a counter frequency of 222.2 MHz. It features in-system programmability via IEEE Std. 1149.1 JTAG and supports MultiVolt I/O levels including 5.0 V, 3.3 V, and 2.5 V. The component is housed in a 100-pin TQFP package.

Complex Programmable Logic Devices Feature Summary

• EEPROM-based architecture supporting up to 100 reprogramming cycles
• In-system programmability through IEEE Std. 1149.1 JTAG interface
• MultiVolt I/O compatibility for 5.0-V, 3.3-V, and 2.5-V logic levels
• Programmable interconnect array for predictable timing performance

Complex Programmable Logic Devices Applications

• PCI Local Bus Specification compliant logic functions
• Transistor-to-transistor logic emulation replacing PALs and GALs
• High-density small-scale integration logic functions

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-7) against the official datasheet to confirm the 7 ns propagation delay specification. Ensure the 100-pin TQFP package designation matches the required board layout constraints. Confirm that the manufacturing source aligns with Altera or authorized Intel distribution channels for authenticity.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require 64 macrocells and 66 user I/O pins within a 100-pin footprint. The -7 speed grade is suitable for applications requiring 7 ns delays, whereas faster options like the -4 grade offer 4.5 ns delays if available in the same package. Consider the MultiVolt capability if interfacing with mixed-voltage peripherals.

Complex Programmable Logic Devices Part Context

This component belongs to the MAX 3000A family, which succeeded earlier MAX series devices. It utilizes the MAX architecture featuring Logic Array Blocks and a Programmable Interconnect Array. The family ranges from 600 to 10,000 usable gates, with the EPM3064A positioned as a mid-range density device offering 1,250 gates.

Complex Programmable Logic Devices Replacement Considerations

The EPM3064A-4N is a faster alternative within the same family offering 4.5 ns delays. Other MAX 3000A variants such as EPM3032A or EPM3128A provide different gate counts but share similar architectural features.
