1. Introduction
1.1 Board Overview
The AM4140 is a highly integrated CPU board implemented as a Single, Mid-size Advanced
Mezzanine Card (AMC) module. The design is based on the Freescale™ QorIQ™ P4080 octal-
core and the Freescale™ QorIQ™ P4040 quad-core Power Architecture® processors with
integrated high-speed interconnect technology to balance processor performance with I/O
system throughput for networking, storage, wireless infrastructure and general-purpose
embedded applications.
The QorIQ™ P4080 and P4040 processors are highly integrated 32-bit system-on-chip (SOC)
platforms that consist of eight and four e500mc cores, respectively, each with 32 kB L1
instruction cache, 32 kB L1 data cache and 128 kB L2 cache. Further processor features
include 2 MB shared L3 CoreNet platform cache, a dual DDR3 memory interface, two 10-Gbit
Ethernet Controllers (10GEC), eight Datapath Triple-Speed Ethernet Controllers (dTSECs),
and either two x4 Serial RapidIO™ fabric interfaces or two x4 PCI Express I/O interfaces.
The board is capable of supporting core frequencies ranging from 1.2 GHz to 1.5 GHz providing
800 MHz platform speed. The processor and the memory are soldered on the AM4140 which
results in higher Mean Time Between Failures (MTBF) and a significant improvement in cooling.
The AM4140 includes up to 8 GB unbuffered Double Data Rate (DDR3) memory with Error
Checking and Correction (ECC) running at up to 1300 MHz. The
two integrated 10 Gigabit Ether-
net controllers and eight dTSECs ensure maximum data throughput between the processor and
the Ethernet infrastructure. The board further provides up to 2 GB flash memory via an onboard
NAND flash controller
.
The AM4140 has full hot swap capability, which enables the board to be replaced, monitored
and controlled without having to shut down the ATCA carrier board or the MicroTCA system. A
dedicated Module Management Controller (MMC) is used to manage the board and support a
defined subset of Intelligent Platform Management Interface (IPMI) commands and PICMG
(ATCA/AMC) command extensions, which enables operators to detect and eliminate faults
faster at module level. This includes monitoring several onboard temperature conditions, board
voltages and the power supply status, managing hot swap operations, rebooting the board, etc.
All in all, IPMI enhances the board’s availability and reliability while reducing the operating
costs and the mean-time-to-repair.
As a “headless” AMC design (no onboard graphics controller), the AM4140 supports one stan-
dard RS-232 serial port (UART1) and up to two Gigabit Ethernet ports on the front panel as well
as a variety of high-speed interconnect topologies to the system. In the Common Options Re-
gion two Gigabit Ethernet SerDes connections are supported. In the Fat Pipes Region either
PCI Express, Serial RapidIO, Gigabit Ethernet SerDes or XAUI connections can be selected. In
the Extended Options Region a debug port and a serial port are provided.
Optimized for high-performance, packet-based telecom systems, the AM4140 is targeted to-
wards, but not limited to the telecom market application such as radio network controllers, me-
dia streaming, traffic processing, database management and routing. The AM4140 also fits into
all applications situated in industrial environments, including I/O intensive applications. The
careful design and the selection of high temperature resistant components ensure a high prod-
uct availability. This, together with a high level of scalability, reliability, and stability, make this
state-of-the-art product a perfect core technology for long-life embedded applications.
