Freescale MPC8308-RDB Mpc8308 powerquicc ii pro processor up Datasheet

Reference Platform Based on Power Architecture® Technology
MPC8308-RDB Reference Platform
Overview
The MPC8308-RDB reference platform is ideal
for hardware and software development for
embedded applications, including consumer
printers, wireless access points, industrial
control and factory automation equipment.
It leverages the low-cost MPC8308
PowerQUICC® II Pro communications
processor, built on Power Architecture®
technology, which is designed to meet the
requirements of several low-end embedded
networking applications with high-speed
peripherals while striving for low power
consumption and a small-footprint package
design. The MPC8308-RDB integrates
leading-edge external components: 5 x
Gigabit Ethernet ports, 1 x USB 2.0, x1 mini
PCI Express® connector and an SD/MMC
card interface. The MPC8308 microprocessor
supports dual 10/100/1000 Mbps Ethernet
controllers, single-lane PCI Express, USB
2.0 controller, enhanced SDHC controller
for SD memory interface, dual universal
asynchronous receiver/transmitter (DUART),
serial peripherals, general-purpose I/O and
system timers. This high level of integration
in the MPC8308 processor helps to lower
overall system costs, improve performance
and simplify board design. The highspeed peripheral mix, combined with cost
effectiveness, makes the MPC8308 processor
a unique offering in the marketplace.
The MPC8308-RDB incorporates a preinstalled board support package (BSP)
containing a boot loader (u-boot)—a generic
Power Architecture technology system based
on the Linux® kernel. The u-boot and Linux
kernel reside in the on-board flash memory
and launch when the board is powered up.

The MPC8308-RDB BSP takes advantage
of the Linux Target Image Builder (LTIB)—a
suite of tools that leverages existing open
source configuration scripts and source code
packages combining them all into a single
BSP generation bundle. The source code
packages, include boot loaders and Linux
kernel sources, as well as many user-space
source code packages, to build a complete
BSP. The LTIB also provides compiler
packages required to build the BSP. Freescale
developers use the LTIB to create BSPs for a
multitude of Freescale development markets.
The LTIB leverages as many BSP elements as
possible for all Freescale markets supported,
while offering the flexibility necessary to
customize components that require platformspecific modifications.
Many third-party applications are available for
the MPC8308-RDB. They are typically built
on top of the BSP delivered by Freescale
and can be installed on the hard disk. To
