Field Programmable Gate Array Procurement Notes

Verify component authenticity as this part number is listed as obsolete or end-of-life by the manufacturer. Confirm RoHS compliance status, as some sources indicate non-compliance while others may list different suffixes. Ensure the specific ordering suffix matches the required voltage and temperature grade specifications before integration into new designs.

Field Programmable Gate Array Selection Notes

Select this device when a system requires embedded memory capabilities alongside general-purpose logic within the FLEX 10K density range. The 144-pin TQFP package is suitable for applications requiring moderate pin counts with surface-mount constraints. Consider the 5.0-V operating voltage requirement and ensure power supply rails align with the 4.75 V to 5.25 V specification.

Field Programmable Gate Array Part Context

This component is part of the Altera FLEX 10K family, recognized as the industry's first embedded PLD family enabling System-on-a-Programmable-Chip (SOPC) integration. It combines an embedded array for megafunctions like memory and DSP with a logic array for general functions. The family supports in-circuit reconfigurability via external configuration devices or JTAG ports.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the FLEX 10K series is legacy technology, modern Intel/Altera FPGA families such as Cyclone or Arria may require significant architectural redesign and pin-out mapping adjustments.
