MPC8313E-RDB reference design board
|
|
The MPC8313 reference platform (MPC8313E-RDB) is a system featuring the powerful PowerQUICC™ II Pro processor, which includes a built-in security accelerator. This low-cost, high-performance system solution consists of a printed circuit board (PCB) assembly known as the MPC8313E-RDB, plus a BSP, distributed in a CD image. MPC8313E-RDB includes Linux® 2.6 BSP with optimized drivers to support all peripherals. This BSP enables fastest possible time-to-market for development or integration of applications including printer engine, broadband gateways, no-new-wires home adapters/access points, and home automation box. |
Application
Printing and imaging, consumer, and industrial
applications, including main CPUs and I/O processors in printing systems,
networking switches and line cards, wireless LANs (WLANs), network access
servers (NAS), VPN routers, intelligent NIC, and industrial controllers.
MPC8313E
Processor
The PowerPC e300c3 core in the MPC8313E, with its 16
Kbytes of instruction and 16 Kbytes of data cache, implements the PowerPC user instruction
set architecture and provides hardware and software debugging support. In
addition, the MPC8313E offers dual three-speed 10/100/1000 Mbps Ethernet
controllers (eTSECs), a DDR-1/DDR-2 SDRAM memory controller, an enhanced local
bus controller (eLBC), a 32-bit PCI-2.3 controller, a dedicated security
engine, a programmable interrupt controller, dual I2C controllers, one 4-channel DMA controller, one
general-purpose I/O port, and one USB 2.0 host and device controller with an
on-chip high-speed USB 2.0 PHY. The high level of integration in the MPC8313E
helps simplify board design and offers significant bandwidth and performance.
