MPC8272 PowerQUICC II™ Family Hardware Specifications, Rev. 1.5

Freescale Semiconductor

Overview

– 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

• Compatible with T1/DS1 24-channel and CEPT E1 32-channel PCM highway, ISDN basic rate,

ISDN primary rate, and user defined.

• Subchanneling on each time slot.

• Independent transmit and receive routing, frame synchronization and clocking

• Concatenation of any not necessarily consecutive time slots to channels independently for Rx/Tx

• Supports H1,H11, and H12 channels

• Allows dynamic allocation of channels

– SCC3 in NMSI mode is not usable when USB is enabled.

— Two serial management controllers (SMCs), identical to those of the MPC860

– Provides management for BRI devices as general-circuit interface (GCI) controllers in

time-division-multiplexed (TDM) channels

– Transparent

– UART (low-speed operation)

— One serial peripheral interface identical to the MPC860 SPI

— One I2C controller (identical to the MPC860 I2C controller)

– Microwire compatible

– Multiple-master, single-master, and slave modes

— Up to two TDM interfaces

– Supports one group of two TDM channels

– 1024 bytes of SI RAM

— Eight independent baud rate generators and 14 input clock pins for supplying clocks to FCC,

SCC, SMC, and USB serial channels

— Four independent 16-bit timers that can be interconnected as two 32-bit timers

•

PCI bridge

— PCI Specification revision 2.2-compliant and supports frequencies up to 66 MHz

— On-chip arbitration

— Support for PCI to 60x memory and 60x memory to PCI streaming

— PCI host bridge or peripheral capabilities

— Includes four DMA channels for the following transfers:

– PCI-to-60x to 60x-to-PCI
