5 / 56 page  MOTOROLA MPC8272 PowerQUICC II™ Family Hardware Specifications 5 PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE Overview • 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 — Serial DMA channels for receive and transmit on all serial channels — Parallel I/O registers with open-drain and interrupt capability — Virtual DMA functionality executing memory-to-memory and memory-to-I/O transfers — Two fast communication controllers (FCCs) supporting the following protocols: – 10-/100-Mbit Ethernet/IEEE 802.3 CDMA/CS interface through media independent interface (MII) – Transparent – HDLC—up to T3 rates (clear channel) – One of the FCCs supports ATM (MPC8272 and MPC8271 only)—full-duplex SAR at 155 Mbps, 8-bit UTOPIA interface 31 Mphys, AAL5, AAL1, AAL2, AAL0 protocols, TM 4.0 CBR, VBR, UBR, ABR traffic types, up to 64-K external connections — Three 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 – QUICC multichannel controller (QMC) up to 64 channels • Independent transmit and receive routing, frame synchronization. • Serial-multiplexed (full-duplex) input/output 2048-, 1544-, and 1536-Kbps PCM highways Freescale Semiconductor, Inc.
