Package and Ordering Notes
The listed package is 8-pin SOIC, industrial grade with 8 pins, leads, lands or contacts. The featured image is a generic package illustration for form-factor identification and is not an actual date-code or lot photograph. Lifecycle is recorded as Obsolete; confirm current factory support and last-time-buy constraints before design-in.
Sourcing Guidance
EPCS1SI8N is obsolete. Intel advised EPCS1 users to migrate to a compatible 4 Mbit alternative; confirm FPGA and programming support before sourcing.
For an accurate quotation, include the full MPN, target quantity, acceptable date-code range, packaging format and destination. Icearth can help review traceability documents, label photos and electrical/package alignment before order placement.
Manufacturer Documentation
Technical values were checked against Intel (Altera) documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
EPCS1SI8N FAQ
What is EPCS1SI8N?
EPCS1SI8N is a Intel (Altera) 1 Mbit serial configuration memory for Intel/Altera FPGA active-serial configuration. It belongs to the EPCS family.
What are the key specifications of EPCS1SI8N?
Memory Density is 1 Mbit, while Configuration Scheme is Active Serial. Check the manufacturer documentation for electrical limits and compatibility conditions.
What package does EPCS1SI8N use?
EPCS1SI8N uses 8-pin SOIC, industrial grade with 8 pins. Confirm the package drawing, land pattern and ordering suffix before PCB release.
What is the lifecycle status of EPCS1SI8N?
Intel PDN1708 discontinued the EPCS family. EPCS1SI8N is therefore recorded as Obsolete.
What should be checked before sourcing or replacing EPCS1SI8N?
Confirm FPGA family support, Quartus programming-file compatibility, supply voltage, pinout and silicon revision before replacing EPCS1SI8N. EPCQ4ASI8N or a supported serial flash after compatibility verification is a migration candidate, not an automatically interchangeable substitute.
