• Supports low current consumption during active configuration and standby modes

Configuration PROMs For FPGAs Applications

• Configuration of ACEX 1K series devices
• Configuration of APEX 20K series devices
• Configuration of FLEX 10KE and FLEX 10KA devices
• Configuration of Mercury series devices

Configuration PROMs For FPGAs Procurement Notes

Verify the specific suffix 'LC' against official datasheets to confirm lead-free status and RoHS compliance, as legacy documentation may vary. Confirm the PDIP-8 package availability matches the required PCB footprint. Check for end-of-life notifications or obsolescence notices from Intel/Altera before finalizing procurement plans.

Configuration PROMs For FPGAs Selection Notes

Select this component when configuring older Altera FPGA families such as ACEX or FLEX that require serial configuration. Ensure the design supports 3.3 V or 5.0 V logic levels. Consider the PDIP-8 package constraints if surface-mount technology is preferred, as alternative packages like PLCC may be available for higher densities.

Configuration PROMs For FPGAs Part Context

This part belongs to the EPC10 serial configuration device family, which serves as a bridge between Altera FPGAs and external configuration storage. It simplifies board design by replacing complex parallel configuration circuits with a simple serial interface, reducing pin count and board space requirements for legacy device families.
