EPM7256AETC144-7

Complex Programmable Logic Devices Overview

The Altera EPM7256AETC144-7 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features 256 macrocells organized into 16 Logic Array Blocks (LABs), providing approximately 5,000 usable gates. The device operates on a 3.3V supply with a maximum propagation delay of 7 ns and supports system-in-programmability via JTAG. It is housed in a 144-pin Thin Quad Flat Pack (TQFP) package.

Complex Programmable Logic Devices Feature Summary

• 256 Macrocells across 16 LABs for high-density logic implementation
• 7 ns maximum propagation delay supporting frequencies up to 172.4 MHz
• 3.3V core voltage with MultiVolt I/O compatibility for 5.0V, 3.3V, and 2.5V levels
• In-system programmability via IEEE 1149.1 JTAG interface

Complex Programmable Logic Devices Applications

• Address decoding and bus bridging in embedded systems
• State machine implementation for industrial control
• Interface translation between different voltage domains
• Replacement for discrete gate arrays in legacy designs

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this part is end-of-life. Check RoHS compliance status, as standard versions may not meet current environmental regulations. Confirm package integrity upon receipt due to potential long-term storage conditions.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells are sufficient for the design. Ensure the 144-pin TQFP footprint matches the PCB layout. Verify that the 3.3V core voltage aligns with the system power architecture and that I/O levels match connected devices.

Complex Programmable Logic Devices Part Context

Part of the MAX 7000A series, designed as a drop-in replacement for older 5.0V MAX 7000S devices. It offers improved performance and lower power consumption while maintaining pin compatibility with previous generations.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible alternatives within the MAX 7000A family include EPM7256AETC144-10 and EPM7256AETI144-7. Higher speed grades like EPM7256AETC144-5 offer faster delays but require careful timing analysis.
