EPM7064AELI44-7

Complex Programmable Logic Devices Overview

The Altera EPM7064AELI44-7 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 input/output pins. 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 is housed in a PLCC-44 surface-mount package. The component supports an industrial temperature range from -40°C to +85°C.

Complex Programmable Logic Devices Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Availability is restricted to surplus or secondary market channels. Verification of authenticity and physical condition is critical due to the age of the product. Buyers should confirm RoHS compliance status, as original specifications may vary based on production date and regional regulations.

Complex Programmable Logic Devices Selection Notes

Select this part when a 3.3 V CPLD with 64 macrocells and PLCC-44 packaging is required. Ensure the design accommodates the 4.5 ns propagation delay and 222.2 MHz maximum frequency. Verify that the PCB layout supports the PLCC-44 footprint and that the system requires EEPROM-based non-volatile configuration rather than volatile SRAM architectures.

Complex Programmable Logic Devices Part Context

The EPM7064AELI44-7 is part of the MAX 7000A series, which succeeded the original MAX 7000 family. This generation introduced improved performance and lower power consumption while maintaining compatibility with existing design tools. The 'AE' suffix denotes the specific variant within the MAX 7000A line, offering enhanced speed grades compared to earlier iterations.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to the EOL status. Potential alternatives include other MAX 7000 variants with compatible pinouts or modern FPGA/CPLD families from Intel/Altera requiring adapter boards. Cross-reference with EPM7064AE series devices for functional equivalence, noting differences in package types and speed grades.
