MPC8309 PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 0

Freescale Semiconductor

Overview

The MPC8309 incorporates the e300c3 (MPC603e-based) core built on Power Architecture® technology,

which includes 16 Kbytes of each L1 instruction and data caches, dual integer units, and on-chip memory

management units (MMUs). The MPC8309 also includes a 32-bit PCI controller, two DMA engines and

a 16/32-bit DDR2 memory controller with 8-bit ECC.

A new communications complex based on QUICC Engine technology forms the heart of the networking

capability of the MPC8309. The QUICC Engine block contains several peripheral controllers and a 32-bit

RISC controller. Protocol support is provided by the main workhorses of the device—the unified

communication controllers (UCCs). A block diagram of the MPC8309 is shown in Figure 1.

Each of the five UCCs can support a variety of communication protocols such as 10/100 Mbps Ethernet

and HDLC.

In summary, the MPC8309 provides users with a highly integrated, fully programmable communications

processor. This helps to ensure that a low-cost system solution can be quickly developed and offers

flexibility to accommodate new standards and evolving system requirements.
