• Manufacturer Part Number: mpc8309
• Description: Powerquicc Ii Pro Integrated Communications Processor Family Hardware Specifications
• Manufacturer: Freescale Semiconductor, Inc

Overview
1
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
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.
