EPM3064ALC44-4N

Complex Programmable Logic Devices Overview

The Altera EPM3064ALC44-4N is a MAX 3000A series Complex Programmable Logic Device (CPLD) housed in a 44-pin Plastic J-Lead Chip Carrier (PLCC) package. It features 1,250 usable gates organized into 64 macrocells and four Logic Array Blocks (LABs). The device supports up to 34 user I/O pins and operates on a 3.3-V supply voltage with MultiVolt I/O compatibility for 5.0-V, 3.3-V, and 2.5-V logic levels. Key electrical parameters include a maximum pin-to-pin propagation delay of 4.5 ns and a counter frequency of 222.2 MHz. It utilizes CMOS EEPROM technology for non-volatile configuration.

Complex Programmable Logic Devices Feature Summary

• EEPROM-based architecture supporting 100 reprogramming cycles and In-System Programming (ISP) via IEEE Std. 1149.1 JTAG interface.
• MultiVolt I/O interface allowing core operation at 3.3 V while supporting 5.0-V, 3.3-V, and 2.5-V I/O levels.
• Programmable Interconnect Array (PIA) providing continuous routing for predictable timing performance.
• Built-in boundary-scan test (BST) circuitry compliant with IEEE Std. 1149.1-1990.

Complex Programmable Logic Devices Applications

• Replacement for PALs, GALs, and other legacy programmable logic devices.
• Implementation of high-density small-scale (SSI), medium-scale (MSI), and large-scale integration (LSI) logic functions.
• PCI Local Bus Specification Revision 2.2 compatible designs requiring fast pin-to-pin delays.

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix '-4N' against official manufacturer documentation to confirm temperature range and RoHS compliance status. The '-4' indicates a 4.5 ns speed grade. Confirm availability as this component may be subject to discontinuation or obsolescence status changes. Ensure the PLCC-44 package footprint matches the target PCB design constraints.

Complex Programmable Logic Devices Selection Notes

Select the EPM3064ALC44-4N when 64 macrocells and 34 I/O pins are required within a 44-pin PLCC package. Choose this part over higher density models like the EPM3128A if cost optimization is prioritized and gate count requirements remain below 2,500. Ensure the design leverages the 3.3-V core voltage while accounting for MultiVolt I/O requirements for mixed-voltage system interfaces.

Complex Programmable Logic Devices Part Context

This component belongs to the Altera MAX 3000A family, which offers low-cost, high-performance CPLDs based on the MAX architecture. The family ranges from 600 to 10,000 usable gates. The EPM3064A variant specifically provides 1,250 gates. Other packages for this device include TQFP-44 and TQFP-100, offering different I/O counts and form factors while maintaining similar architectural features.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements within the same package and pinout are limited due to the discontinued nature of the MAX 3000A line. Consider the EPM3064ATC100-4N for a TQFP-44 package alternative. For modern equivalents, evaluate Intel MAX 10 or Cyclone IV families, though these require significant schematic and software migration efforts.
