Device Overview

Summary

The KSZ8841-series of single-port controllers includes PCI and non-PCI CPU interfaces.

The KSZ8841-PMQL datasheet describes PCI CPU interface chips. KSZ8841-PMQL is PQFP package chip. For information on the non-PCI controller, refer to the KSZ8841-MQL datasheet.

The KSZ8841-PMQL is a single port Fast Ethernet MAC chip with 32-bit/33MHz PCI processor interface.  Fully compliant with IEEE 802.3u, it is also available in industrial temperature grades. The KSZ8841MQL has 32-, 16- or 8-bit generic host processor interface.

Microchip's complimentary and confidential LANCheck® online design review service is available for customers who have selected our products for their application design-in. The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
