EPM7256AETC100-7N

Complex Programmable Logic Devices Overview

The Altera EPM7256AETC100-7N 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 3.0 V to 3.6 V supply voltage and offers 84 user I/O pins within a TQFP-100 surface-mount package. Key electrical specifications include a maximum propagation delay of 5.5 ns and a maximum operating frequency of 172.4 MHz. It utilizes EEPROM technology for non-volatile configuration and supports System In-Programmability (SIP).

Complex Programmable Logic Devices Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Availability is restricted to existing stock or surplus markets. Verification of authenticity and physical condition is critical when sourcing from third-party distributors due to the discontinued status. Ensure compliance with RoHS requirements if applicable to specific project constraints.

Complex Programmable Logic Devices Selection Notes

Select this part when a moderate logic density (256 macrocells) and high speed (5.5 ns delay) are required in a compact TQFP-100 footprint. It serves as a direct replacement for legacy CPLDs requiring 84 I/Os. Consider alternative MAX 7000 variants if different pin counts or temperature ranges are needed, noting that this specific suffix denotes commercial temperature range (0°C to +70°C).

Complex Programmable Logic Devices Part Context

The EPM7256AETC100-7N is part of the MAX 7000AE series, an evolution of Intel's (formerly Altera) popular MAX 7000 architecture. This series is known for its fast, deterministic timing and ease of use compared to FPGAs. The 'AE' suffix indicates enhanced speed grades and features over the original MAX 7000A series, while the 'ETC' indicates the TQFP package and commercial temperature rating.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be limited due to the EOL status. Potential alternatives within the same family include the EPM7256AETC100-10N (slower speed grade) or other MAX 7000AE devices with compatible I/O counts. Cross-referencing with newer Intel MAX 10 or Agilex families requires significant redesign.
