Freescale Semiconductor

MPC8544E Overview

– General-purpose chip select machine (GPCM)

– Three user programmable machines (UPMs)

— Parity support

— Default boot ROM chip select with configurable bus width (8, 16, or 32 bits)

•

Two enhanced three-speed Ethernet controllers (eTSECs)

— Three-speed support (10/100/1000 Mbps)

— Two IEEE Std 802.3™, IEEE 802.3u, IEEE 802.3x, IEEE 802.3z, IEEE 802.3ac, and

IEEE 802.3ab-compliant controllers

— Support for various Ethernet physical interfaces:

– 1000 Mbps full-duplex IEEE 802.3 GMII, IEEE 802.3z TBI, RTBI, SGMII, and RGMII.

– 10/100 Mbps full- and half-duplex IEEE 802.3 MII, IEEE 802.3 RGMII, and RMII.

— Flexible configuration for multiple PHY interface configurations.

— TCP/IP acceleration and QoS features available

– IP v4 and IP v6 header recognition on receive

– IP v4 header checksum verification and generation

– TCP and UDP checksum verification and generation

– Per-packet configurable acceleration

– Recognition of VLAN, stacked (queue in queue) VLAN, 802.2, PPPoE session, MPLS

stacks, and ESP/AH IP-security headers

– Supported in all FIFO modes

— Quality of service support:

– Transmission from up to eight physical queues

– Reception to up to eight physical queues

— Full- and half-duplex Ethernet support (1000 Mbps supports only full duplex):

– IEEE 802.3 full-duplex flow control (automatic PAUSE frame generation or

software-programmed PAUSE frame generation and recognition)

— Programmable maximum frame length supports jumbo frames (up to 9.6 Kbytes) and

IEEE Std 802.1™ virtual local area network (VLAN) tags and priority

— VLAN insertion and deletion

– Per-frame VLAN control word or default VLAN for each eTSEC

– Extracted VLAN control word passed to software separately

— Retransmission following a collision

— CRC generation and verification of inbound/outbound frames

— Programmable Ethernet preamble insertion and extraction of up to 7 bytes

— MAC address recognition:

– Exact match on primary and virtual 48-bit unicast addresses

– VRRP and HSRP support for seamless router fail-over

– Up to 16 exact-match MAC addresses supported
