PowerPC processor adds Fast Ethernet on chip

Based on the PowerPC 440 superscalar core, the low cost AMCC 440GR offers increased processor speed, memory performance and integrated dual Fast Ethernets.

Based on the PowerPC 440 superscalar core, the low cost AMCC 440GR offers increased processor speed, memory performance and integrated dual Fast Ethernets.

Ideal for line card, system control and multi-radio devices, the AMCC 440GR operates at a clock frequency of up to 667MHz.

The AMCC 440GR requires one-third less power than any other member of the 440 family, making it ideal for low power applications.

The AMCC 440GR's dual Fast Ethernet controllers function at full or half duplex at 10/100Mbit/s.

They are configurable as one MII, two RMII, or two SMII ports with a packet reject interface.

Along with a 65% increase in performance over AMCC's 405GPr, the AMCC 440GR also supports double datarate memory (DDR266) with a peak bandwidth of 1.1Gbit/s.

Optional ECC support is also provided.

In addition, the 440GR supports a 32bit PCI revision 2.2 compliant interface with multiple read prefetch and write post buffers and the ability to boot the processor from PCI bus memory.

The 440GR's external bus controller provides support for up to six ROM, EPROM, SRAM, Flash or slave peripheral I/O devices.

The 440GR also incorporates a DMA controller with four independent channels supporting memory-to-memory, peripheral-to-memory and memory-to-peripheral block transfers.

Other on-chip peripherals on the AMCC 440GR include two IIC controllers, one bootstrap controller (BSC) and one SPI serial communications port (SCP), up to 10 external interrupts, general purpose timers, 53 GPIO pins and four UARTs to support various functions in user applications.

"We are very excited about the addition of the AMCC 440GR to our current portfolio of feature-rich processors".

"The AMCC 440GR is a great choice for new storage and networking applications as well as an excellent growth path for existing 405xx users requiring increased processor speed, memory performance, and Fast Ethernet at a low cost", commented Sam Fuller, AMCC's Vice President of Marketing, Embedded Products.

AMCC's PowerPC processors are supported by AMCC and more than 100 third-party vendors who provide a full range of software, boards and tools necessary for manufacturers to develop products quickly and efficiently.

The AMCC 440GR will be shipping in the second quarter of 2005.
