MPC8323E PowerQUICC™ II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 3

Freescale Semiconductor

Overview

1.1.2

Serial Interfaces

The MPC8323E serial interfaces are as follows:

•

Support for one UL2 interface with 31 multi-PHY addresses (MPC8323E and MPC8323 only)

•

Support for up to three 10/100 Mbps Ethernet interfaces using MII or RMII

•

Support for up to four T1/E1/J1/E3 or DS-3 serial interfaces (TDM)

•

Support for dual UART and SPI interfaces and a single I2C interface

1.2

QUICC Engine Block

The QUICC Engine block is a versatile communications complex that integrates several communications

peripheral controllers. It provides on-chip system design for a variety of applications, particularly in

communications and networking systems. The QUICC Engine block has the following features:

•

One 32-bit RISC controller for flexible support of the communications peripherals

•

Serial DMA channel for receive and transmit on all serial channels

•

Five universal communication controllers (UCCs) supporting the following protocols and

interfaces (not all of them simultaneously):

— 10/100 Mbps Ethernet/IEEE 802.3® standard

— IP support for IPv4 and IPv6 packets including TOS, TTL, and header checksum processing

— ATM protocol through UTOPIA interface (note that the MPC8321 and MPC8321E do not

support the UTOPIA interface)

— HDLC /transparent up to 70-Mbps full-duplex

— HDLC bus up to 10 Mbps

— Asynchronous HDLC

— UART

— BISYNC up to 2 Mbps

— QUICC multi-channel controller (QMC) for 64 TDM channels

•

One UTOPIA interface (UPC1) supporting 31 multi-PHYs (MPC8323E- and MPC8323-specific)

•

Two serial peripheral interfaces (SPI). SPI2 is dedicated to Ethernet PHY management.

•

Four TDM interfaces

•

Thirteen independent baud rate generators and 19 input clock pins for supplying clocks to UCC

serial channels

•

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

The UCCs are similar to the PowerQUICC II peripherals: SCC (BISYNC, UART, and HDLC bus) and

FCC (fast Ethernet, HDLC, transparent, and ATM).
