EPM7128ATC144-6

Complex Programmable Logic Devices Overview

The Altera EPM7128ATC144-6 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features an EEPROM-based non-volatile configuration structure with 128 macrocells and 84 I/O pins housed in a TQFP-144 package. The device operates at a supply voltage of 3.3V, supporting In-System Programming (ISP) via IEEE Std. 1149.1 JTAG. Key electrical parameters include a maximum propagation delay of 6ns and a maximum operating frequency of 147.1 MHz. It supports industrial temperature ranges from -40°C to +85°C.

Complex Programmable Logic Devices Feature Summary

• 128 Macrocells organized into 8 Logic Array Blocks (LABs)
• 3.3V EEPROM technology enabling non-vatile logic retention
• In-System Programmability (ISP) through built-in JTAG interface
• High-performance speed grade with 6ns max propagation delay

Complex Programmable Logic Devices Applications

• Data merging converters for serial-to-PCM stream processing
• Address decoding and bus arbitration in embedded systems
• Protocol conversion and interface bridging between digital components
• State machine implementation for industrial control logic

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to potential availability of refurbished units. Confirm RoHS compliance status as original versions may be leaded. Check for moisture sensitivity level (MSL) handling requirements if storage conditions are uncertain. Ensure programming tools support the specific MAX 7000A architecture for reliable ISP operations.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and 84 I/Os are sufficient for the design. The 6ns speed grade suits applications requiring moderate timing performance. Choose the TQFP-144 package for surface-mount assembly needs. Verify that the system operates at 3.3V, as this variant is not compatible with 5V logic levels without level shifting.

Complex Programmable Logic Devices Part Context

This part belongs to the Altera MAX 7000A series, which utilizes second-generation Multiple Array MatriX (MAX) architecture. It succeeded earlier MAX 7000 variants by offering improved performance and lower power consumption while maintaining backward compatibility with existing design flows and pinouts within the family.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package include other speed grades of the EPM7128ATC144 series, such as EPM7128ATC144-10 or EPM7128ATC144-15, provided timing constraints allow for slower speeds.
