LAN9221-ABZJ, Ethernet Controller, Ethernet Controller, IEEE 802.3, IEEE 802.3u, 3 V, 3.6 V, QFN, 56 Pins

Semiconductors - ICs\Network Controllers\Ethernet Controllers The LAN9221-ABZJ is a high-performance 16-bit Non-PCI 10/100 Ethernet Controller with variable voltage I/O. It has been specifically designed to provide high performance and throughput for 16-bit applications. It is fully IEEE 802.3 10Base-T and 802.3u 100Base-TX compliant and supports HP Auto-MDIX. The variable voltage I/O signals of the LAN9221 accommodate lower voltage I/O signalling without the need for voltage level shifters. It includes an integrated Ethernet MAC and PHY. The simple, yet highly functional host bus interface provides a glue-less connection to most common 16-bit microprocessors and microcontrollers as well as 32-bit microprocessors with a 16-bit external bus. The integrated checksum offload engines enable the automatic generation of the 16-bit checksum for received and transmitted Ethernet frames, offloading the task from the CPU. • Efficient architecture with low CPU overhead • Easily interfaces to most 16-bit embedded CPU’s • Integrated PHY with HP Auto-MDIX support • Integrated checksum offload engine helps reduce CPU load • Low pin count and small body size package for small form factor system designs • Burst-mode read support • Internal buffer memory can store over 200 packets • Automatic PAUSE and back-pressure flow control • Interrupt pin with programmable hold-off timer • Reduces system cost and increases design flexibility • SRAM-like interface easily interfaces to most embedded CPU’s or SoC’s • Fully compliant with IEEE 802.3/802.3u standards • Integrated Ethernet MAC and PHY • Full- and half-duplex support • Full-duplex flow control • Backpressure for half-duplex flow control • Preamble generation and removal • Automatic 32-bit CRC generation and checking • Automatic payload padding and pad removal • Loop-back modes
