EPM7256AETC144-7N

Complex Programmable Logic Devices Overview

The Altera EPM7256AETC144-7N is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000AE 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 core voltage with MultiVolt I/O compatibility for 5.0V, 3.3V, and 2.5V interfaces. It supports In-System Programming (ISP) via IEEE Std. 1149.1 JTAG and includes boundary-scan test circuitry. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and offers a maximum propagation delay of 7 ns.

Complex Programmable Logic Devices Feature Summary

• 256 Macrocells and 16 LABs within the MAX 7000AE architecture
• In-System Programmability (ISP) compliant with IEEE Std. 1149.1 and 1532
• MultiVolt I/O interface supporting 5.0V, 3.3V, and 2.5V logic levels
• 7 ns maximum propagation delay with 120 user I/O pins

Complex Programmable Logic Devices Applications

• Replacement for legacy 5.0V PLDs in mixed-voltage systems
• Address decoding and bus bridging in embedded controllers
• State machine implementation for industrial automation
• Interface logic conversion between different voltage domains

Complex Programmable Logic Devices Procurement Notes

Verify RoHS compliance status as historical data indicates non-compliance for some variants. Confirm end-of-life (EOL) status through official Intel/Altera channels prior to design finalization. Ensure programming tools support the specific ISP requirements of the MAX 7000AE series.

Complex Programmable Logic Devices Selection Notes

Select this model when pin-count compatibility with older MAX 7000S devices is required alongside 3.3V operation. The 7 ns speed grade suits applications requiring deterministic timing under 10 ns. Consider the TQFP-144 package constraints for PCB layout if manual soldering or rework capabilities are necessary.

Complex Programmable Logic Devices Part Context

This component is part of the second-generation MAX architecture, designed to bridge the gap between simple PLDs and high-density FPGAs. It serves as a drop-in replacement for 5.0V MAX 7000S devices while offering lower power consumption through 3.3V core operation. The EEPROM-based configuration allows for non-volatile storage without external memory.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible with MAX 7000S series devices. Verify voltage level translation requirements if interfacing with pure 5.0V logic without MultiVolt support.
