EPM7064AETC44-7N

Complex Programmable Logic Devices Overview

The Altera EPM7064AETC44-7N is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features an EEPROM-based architecture with 64 macrocells and supports in-system programmability via JTAG. The device operates at a maximum frequency of 222.2 MHz with a propagation delay of 4.5 ns. It utilizes a 44-pin TQFP package, offers 36 I/O lines, and functions within a supply voltage range of 3.0 V to 3.6 V across an industrial temperature range of -40°C to +85°C.

Complex Programmable Logic Devices Feature Summary

• EEPROM non-volatile configuration allowing immediate operation upon power-up without external memory
• In-system programmability (ISP) capability for design updates without removing the device from the circuit
• High-speed performance with 4.5 ns maximum propagation delay and 222.2 MHz clock frequency
• Industrial temperature rating (-40°C to +85°C) suitable for demanding environments

Complex Programmable Logic Devices Applications

• Protocol conversion and interface bridging in communication equipment
• Address decoding and control logic in industrial automation systems
• State machine implementation for embedded controllers
• Logic expansion for microprocessors and ASICs

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers due to potential availability issues. Confirm RoHS compliance status as historical data indicates variations. Ensure proper handling procedures are followed during assembly to prevent electrostatic discharge damage to the CMOS structure.

Complex Programmable Logic Devices Selection Notes

Select this model when non-volatile storage is required to eliminate external configuration chips. Compare against the EPM7064STC44-15 if higher speed is needed but ISP is not critical. Evaluate pin count requirements carefully as the 44-pin TQFP limits available I/O to 36 lines compared to larger packages.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000 series, representing second-generation CPLD technology from Altera. It serves as a cost-effective solution for medium-density logic applications where low power consumption and ease of use are prioritized over the high complexity of FPGAs.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes include other MAX 7000 variants such as the EPM7064STC44-15 or EPM7064LC44-15, provided package compatibility and speed grades meet specific design constraints.
