EPX740LC68-15

Complex Programmable Logic Devices Overview

The EPX740LC68-15 is an Excalibur programmable logic device (PLD) manufactured by Altera. It features a CMOS technology with a maximum clock frequency of 50 MHz and a propagation delay of 18 ns. The device is housed in a 68-pin Plastic Quad Flat Package (PQCC), specifically identified as LCC-68. It contains 40 macrocells organized into 4 LABs, supporting configurable I/O operation at either 3.3V or 5V levels. The architecture includes 10 dedicated inputs and 40 I/O lines, with a total of 52 input/output pins accessible within the package.

Complex Programmable Logic Devices Feature Summary

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or certified suppliers. Confirm that the specific suffix matches the required performance grade. Check for lead-free compliance status if RoHS regulations apply to the target assembly process. Ensure storage conditions prevent moisture damage prior to soldering.

Complex Programmable Logic Devices Selection Notes

Select this component when a fixed-function PLD solution is preferred over FPGA flexibility. The 40-macrocell capacity suits designs with moderate pin counts. Verify that the 50 MHz speed meets timing requirements. Consider the 68-pin package dimensions for PCB layout constraints compared to smaller packages.

Complex Programmable Logic Devices Part Context

This part belongs to the Altera Excalibur family, which integrates ARM processors with programmable logic. The EPX740 variant specifically provides the logic resources necessary for embedded control tasks. It represents a legacy generation of mixed-signal programmable devices from Intel/Altera.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may not exist due to the specific Excalibur architecture. Evaluate newer Altera Cyclone or MAX families for logical equivalence, noting differences in configuration methods and I/O standards.
