EPM7064AELC44-7

Complex Programmable Logic Devices Overview

The Altera EPM7064AELC44-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features 64 macrocells organized into four Logic Array Blocks (LABs) and provides 36 I/O pins within a PLCC-44 package. The device operates at a supply voltage of 3.3 V, with a maximum operating frequency of 222.2 MHz and a typical propagation delay of 4.5 ns. It utilizes EEPROM technology for non-volatile configuration storage and supports System In-System Programming (ISP). The component is rated for commercial temperature ranges from 0°C to +70°C.

Complex Programmable Logic Devices Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and verification of authenticity is critical due to potential obsolescence. Buyers should confirm the specific revision level and ensure compliance with current environmental regulations, noting that RoHS status may vary or be non-compliant depending on production date.

Complex Programmable Logic Devices Selection Notes

Select this part when 64 macrocells are sufficient for the design logic. Ensure the application requires 3.3 V logic levels, as this variant is not compatible with 5 V systems without level shifting. Verify that the PLCC-44 footprint matches the PCB layout. For higher performance or lower voltage requirements, consider the EPM7064B series or newer MAX families.

Complex Programmable Logic Devices Part Context

The EPM7064AELC44-7 is part of the second-generation MAX architecture, designed to replace older GAL devices. It offers high density for its era with EEPROM technology allowing reprogramming. The 'AE' suffix denotes the 3.3 V version, while 'LC44' indicates the Leadless Ceramic Chip Carrier package with 44 pins. It serves as a bridge between simple PLDs and more complex FPGAs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to EOL status. Potential functional equivalents include the EPM7064SLC44-5 (5V ISP version) if voltage compatibility allows, or the EPM7064S series for JTAG support. Modern alternatives such as the MAX 10 or Cyclone IV series require significant redesign but offer better availability and performance.
