MPC8272 PowerQUICC II Family Hardware Specifications, Rev. 3

Freescale Semiconductor

Overview

– 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

• 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 receiver/transmitter

• 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

s 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
