MPC8280 PowerQUICC II Family Hardware Specifications, Rev. 2
6
Freescale Semiconductor
Overview
– ATM—Full-duplex SAR protocols at 155 Mbps, through UTOPIA interface, AAL5, AAL1,
AAL0 protocols, TM 4.0 CBR, VBR, UBR, ABR traffic types, up to 64 K external
connections (no ATM support for the MPC8270)
– Transparent
– HDLC—Up to T3 rates (clear channel)
– FCC2 can also be connected to the TC layer (MPC8280 only)
— Two multichannel controllers (MCCs) (one MCC on the MPC8270)
– Each MCC handles 128 serial, full-duplex, 64-Kbps data channels. Each MCC can be split
into four subgroups of 32 channels each.
– Almost any combination of subgroups can be multiplexed to single or multiple TDM
interfaces up to four TDM interfaces per MCC
— Four serial communications controllers (SCCs) identical to those on the MPC860, supporting
the digital portions of the following protocols:
– Ethernet/IEEE 802.3 CDMA/CS
– HDLC/SDLC and HDLC bus
– Universal asynchronous receiver transmitter (UART)
– Synchronous UART
– Binary synchronous (BISYNC) communications
– Transparent
Universal serial bus (USB) controller
— Supports USB 2.0 full/low rate compatible
— USB host mode
– Supports control, bulk, interrupt, and isochronous data transfers
– CRC16 generation and checking
– NRZI encoding/decoding with bit stuffing
– Supports both 12- and 1.5-Mbps data rates (automatic generation of preamble token and
data rate configuration). Note that low-speed operation requires an external hub.
– Flexible data buffers with multiple buffers per frame
– Supports local loopback mode for diagnostics (12 Mbps only)
— Supports USB slave mode
– Four independent endpoints support control, bulk, interrupt, and isochronous data transfers
– CRC16 generation and checking
– CRC5 checking
– NRZI encoding/decoding with bit stuffing
– 12- or 1.5-Mbps data rate
– Flexible data buffers with multiple buffers per frame
– Automatic retransmission upon transmit error
— Two serial management controllers (SMCs), identical to those of the MPC860
