Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as older manufacturing runs may differ from current standards. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the specific ordering suffix matches the required speed grade and package variant for the target application.

Complex Programmable Logic Devices Selection Notes

Select this model when 5.0-V ISP capability and high-density logic are required. The -15 speed grade provides a 6 ns delay suitable for moderate-speed synchronous designs. Consider alternative packages if board space constraints require BGA or PLCC form factors. Verify voltage compatibility with downstream 3.3-V logic using MultiVolt I/O configurations where supported by the specific pinout.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000S series, representing the second-generation MAX architecture. It serves as a bridge between traditional discrete logic and modern FPGA technologies. The MAX 7000S family specifically introduced in-system programmability to standard MAX 7000 devices, allowing field updates without removing the chip from the PCB.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other EPM7128 variants such as EPM7128SQC100-10 or EPM7128E series devices, provided speed grades meet design requirements. Cross-family migration to MAX 7000A or MAX 7000B requires verification of voltage level shifts and programming interface differences.
