EPM3064ALC44-7N

Complex Programmable Logic Devices Overview

The Altera EPM3064ALC44-7N is a CMOS EEPROM-based Complex Programmable Logic Device (CPLD) belonging to the MAX 3000A family. It features 1,250 usable gates organized into 64 macrocells distributed across four Logic Array Blocks (LABs). The device operates at a supply voltage of 3.3 V with a maximum frequency of 222.2 MHz and a typical pin-to-pin propagation delay of 4.5 ns. It supports in-system programming 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. The component is housed in a 44-pin PLCC package and functions within an industrial temperature range.

Complex Programmable Logic Devices Feature Summary

• EEPROM-based architecture supporting up to 100 reprogramming cycles
• In-system programmability (ISP) via IEEE Std. 1149.1 JTAG interface
• MultiVolt I/O interface compatible with 5.0-V, 3.3-V, and 2.5-V logic
• Programmable interconnect array (PIA) providing predictable timing performance

Complex Programmable Logic Devices Applications

• Transistor-to-transistor logic (TTL) emulation
• Small-scale integration (SSI), medium-scale integration (MSI), and large-scale integration (LSI) logic functions
• PCI Local Bus Specification compliant designs
• Mixed-voltage system interfacing

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized channels as this part number may be subject to obsolescence. Confirm that the specific ordering suffix corresponds to the required package type and speed grade. Ensure design files are compatible with the MAX 3000A device family specifications before procurement.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells and 34 user I/O pins are sufficient for the design requirements. The -7N suffix indicates the 44-pin PLCC package variant. Consider the -10 speed grade if stricter timing margins are needed, or the ATC44 package if TQFP form factor is preferred. Verify power consumption constraints against the programmable power-saving mode capabilities.

Complex Programmable Logic Devices Part Context

This device is part of the Altera MAX 3000A series, which utilizes a high-performance PLA-like architecture. It serves as a drop-in replacement for legacy PALs, GALs, and pLSI devices. The family shares common development tools such as Quartus II software and supports standard programming cables like ByteBlasterMV.

Complex Programmable Logic Devices Replacement Considerations

Direct functional equivalents within the same density include other EPM3064A variants with different packages (e.g., EPM3064ATC44-10N) or speed grades. Cross-family migration to MAX 10 or Cyclone IV requires architectural redesign due to FPGA vs. CPLD differences.
