MPC8540 reference platform 

(MPC8540 Processor card + Type-N/S/A carrier)

(Above is the pictures for MPC8540 reference board)


MPC8540PC services as a general-purpose PQ37PC processor card and supports Freescale MPC8540/8541E/8555E/8560 processor. The reusable processor card integrates CPU (8540) and some periphery circuit and can be flexibly combined with Type-N, Type-S or Type-A carrier for different applications, such as networking, storage and ATCA or MicroTCA Chassis. It reduces the design cycle  and saves the investment for the designer.

Addressing the needs for higher compute density and lower system cost, Freescale Semiconductor's MPC8540 integrated host processor is designed to provide the highest level of performance and integration available today. The MPC8540 is Freescale's first device utilizing the e500 core; is the industry's first RapidIO-enabled processor; and provides dual gigabit Ethernet controllers. Balancing processor performance with I/O system throughput, the MPC8540 is a powerful control element for network routers and switches, storage subsystems, network appliances, and print and imaging devices.

Advantages of Using the PQ37PC

The PQ37PC is designed to contain the mandatory memories (DDR and flash) and system logics (latch and buffer) only. However, it supports wide range of peripherals/interfaces, for example ATM, 10/100/1000 Base-T Ethernet, UART, through the I/O connectors and a corresponding carrier board. The following sections describe the advantages of using the PQ37PC.

1 Flexibility

The PowerQUICCTM family devices are highly flexible that can support many kinds of peripheral and protocol. A single reference board can never satisfy all desired requirements. To support different peripherals and protocols with limited budget, a system consist of a processor card plus a carrier board is desired. In the PQ37PC, the entire CPM I/O, PCI bus, Local Bus signals are fanout to the I/O connectors. User can easily incorporate their own carrier system with the PQ37PC as most of the I/Os are available on the card.

2 Shortening of the design cycle

The PowerQUICC IIITM is a highly integrated and complicated device, which works with many high-speed interfaces. Designing these high speed interfaces always increase the development cycle if a user does not familiar with the PowerQUICC IIITM family. The PQ37PC is convenient for user on fast prototyping because user need not to put many affords on PowerQUICC IIITM design with using the PQ37PC, but only focus on his own carrier board. The most convenient way is plugging the PQ37PC into the Type-N carrier board.

3 Reusability

The PCB dimension and the assignment of connection signals between the PQ37PC and the carrier board are fixed. User can easily upgrade or modify the PQ37PC with our processors, such as PowerQUICC IIITM Hip8 devices, PowerQUICC IITM Pro family, while keeping the peripherals on the carrier board unchanged.

4 Ease of Debug

The architecture of the PQ37PC plus carrier board separates the main system from the peripherals. It ease user’s debugging effort by isolating the problem at the main system upon the proven peripherals or vice versa, instead of debugging a messy system with all peripherals integrated on a single board.

5 Standardized reference

The PQ37PC is in PMC form factor which allows user to fit the processor card into his own system board with minimum effort.
