ENC28J60-I/SS is a Microchip ENC28J60 stand-alone Ethernet controller with SPI interface — integrated MAC and 10Base-T PHY, 8 KB transmit/receive packet buffer, SPI clock up to 20 MHz, in 28-pin SSOP, tube packing, -40 to +85 °C industrial grade (the I suffix). On-chip MAC plus PHY is the selection point: Ethernet for any microcontroller that has SPI, with internal DMA and hardware checksum assist to keep small MCUs fast. Selection advice: this is 10Base-T only — for 100 Mbps choose a different controller family. You must add external magnetics and an RJ45 jack; the chip handles the protocol, not the magnetics. The 3.1-3.6 V supply with 5 V-tolerant inputs suits 3.3 V logic designs, and the industrial temperature range covers outdoor and factory installations where the commercial (non-I) grade does not. Evidence: Microchip ENC28J60 datasheet (DS39662C) and distributor listings confirm SPI, MAC+PHY, 8 KB RAM, SSOP-28 and -40 to +85 °C. Match the full ENC28J60-I/SS code for grade and package. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
ENC28J60-I/SS is a Ethernet controller from Microchip Technology, orderable in the SSOP-28 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.
When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.

Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. ENC28J60-I/SS names the SSOP-28 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.
The package (SSOP-28) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.
Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.
Add ENC28J60-I/SS to your RFQ with the complete ordering code, the manufacturer (Microchip Technology), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
