LAN9221-ABZJ Beschreibung

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-ABZJ accommodate lower voltage I/O signalling without the need for voltage level shifters. It includes an integrated Ethernet MAC and PHY with a high-performance SRAM-like slave interface. 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
  • Supports Slave-DMA
  • 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
