Embedded Processor
440G
R
With speeds of up to 667MHz,support for DDR memory, ethernet and NAND
flash interfaces, low power dissipation and a small footprint, the PowerPC
440GR embedded processor is ideally suited to a wide range of high-
performance applications, including networking and storage.
The 440GR is an excellent choice for 405xx users requiring additional
performance or looking to upgrade to DDR memory.
The PowerPC 440 Core
To enhance overall throughput, the PowerPC 440
superscalar core incorporates a 7-stage pipeline and
executes up to two instructions per cycle. Its large
32KB data cache and 32KB instruction cache are 64-
way set-associative. Versatile configurations enhance
performance tuning while optional parity protection
preserves data integrity. For additional system
performance, the PowerPC 440 core includes
dynamic branch prediction and 24 digital signal
processing (DSP) instructions, as well as non-
blocking caches that can be managed in either write-
through or write-back mode.
High Speed Bus Architecture
Offering a peak bandwidth of 4.2GBps and separate
read and write data buses -- the PowerPC 440GR's
Processor Local Bus (PLB) provides a high-band-
width connection between the processor core and
memory controller. Less demanding I/O devices are
served by a 30-bit On-chip Peripheral Bus (OPB).
Extensive Memory Support
An on-chip Double Data Rate (DDR) SDRAM
controller provides a 32-bit memory interface with
optional Error Checking and Correcting (ECC) and a
1.1 GBps peak data rate. It supports 4 memory banks
of up to 256MB each, for a maximum capacity of 1GB.
An integrated Nand Flash controller allows up to four
banks of Flash memory devices to be connected to
the processor's external peripheral bus.
The Flash controller supports device densities up to
512MB,an optional SmartMedia card interface.
These devices can be accessed much like diskette
drives, with available boot capability.
PCI Interface
The PowerPC 440GR offers a 32-bit PCI V2.2 interface
and supports frequencies of up to 66MHz.Multiple
read prefetch and write post buffers enhance
throughput, while the ability to boot the processor
from PCI bus memory increases functionality.
Dual Ethernet Ports
For extensive connectivity options, the 440GR offers
two integrated 10/100 Ethernet ports.
Standard Peripherals
The PowerPC 440GR offers two serial ports, support
for up to 64 General Purpose I/O (GPIO) and two IIC
controllers. A serial peripheral interface (SPI), also
referred to as a serial communications port (SCP),
allows full-duplex, synchronous data exchanges with
other serial devices. The 440GR also supports up to
four UARTs in a variety of configurations. A JTAG
interface is provided for debugging purposes.
Development tools support
PowerPC embedded processors are supported by
AMCC and more than one hundred third-party
vendors through the PowerPC Embedded Tools
program. This program provides compilers,
debuggers, real-time operating systems, emulators,
logic analyzers, and a full range of tools to help
manufacturers develop products more quickly. A
PowerPC 440GR reference board kit is available to
help expedite product evaluation and project
development.
