EPM7256AEQC208-5

Complex Programmable Logic Devices Overview

The Altera EPM7256AEQC208-5 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features 256 macrocells, 16 Logic Array Blocks (LABs), and 164 I/O pins housed in a PQFP-208 package. The device operates at a supply voltage of 3.0 V to 3.6 V with a typical 3.3 V rating. Key electrical parameters 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 an industrial temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Procurement Notes

This component is listed as discontinued by the manufacturer. Verification of authenticity is critical when sourcing from secondary markets. Check for moisture sensitivity indicators and verify package integrity, as the PQFP-208 form factor requires careful handling during reflow soldering processes.

Complex Programmable Logic Devices Selection Notes

Select this part when a high pin count (164 I/O) and moderate logic density (256 macrocells) are required in a surface-mount package. Ensure the design accommodates the 3.3 V I/O levels and that the PCB layout supports the thermal requirements of the PQFP-208 package within the specified 0°C to +70°C operating range.

Complex Programmable Logic Devices Part Context

The EPM7256AEQC208-5 is part of the MAX 7000A series, which succeeded the original MAX 7000 line. It shares architectural similarities with other devices in the EPM7256AE family but differs in package type and speed grade. The 'QC' suffix denotes the PQFP-208 package, while the '-5' indicates the specific speed grade optimized for 5.5 ns delays.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be found within the same MAX 7000A family, such as the EPM7256AEQC208-6 or EPM7256AEQC208-10, depending on timing requirements. Verify that alternative packages maintain the 208-pin footprint and compatible I/O voltage specifications.
