EPM7256AETC144-10

Complex Programmable Logic Devices Overview

The Altera EPM7256AETC144-10 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 at a supply voltage of 3.0 V to 3.6 V and supports System In-Programmability via EEPROM technology. Key electrical parameters include a maximum propagation delay of 5.5 ns, a maximum operating frequency of 172.4 MHz, and 36 I/O pins. It is housed in a 144-pin TQFP package with an industrial temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Procurement Notes

This component is officially listed as End-of-Life (EOL). Verification of authenticity is critical due to potential availability from third-party sources. Confirm RoHS compliance status, as specific variants may not meet current environmental standards. Check for recent Product Change Notices regarding labeling or packaging updates before procurement.

Complex Programmable Logic Devices Selection Notes

Select this part when a moderate logic density (256 macrocells) is required with fast combinatorial delays. It serves as a direct replacement for older MAX 7000 series devices. Ensure the design utilizes the available 36 I/O pins effectively. Consider the 144-TQFP footprint constraints during PCB layout planning.

Complex Programmable Logic Devices Part Context

The EPM7256AETC144-10 is part of the broader EPM7256AE series, distinguished by its 144-pin Thin Quad Flat Package (TQFP) and -10 speed grade. It shares core logic resources with other variants like the EPM7256AETI144-5 but offers different thermal and speed characteristics defined by the suffix codes.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package are limited due to the EOL status. Review the EPM7256AETI144-5 for similar logic capacity if higher speed grades are acceptable. For modern equivalents, consider Intel MAX 10 or Cyclone IV families, though these require significant redesign.
