440GP – Power PC 440GP Embedded Processor

AMCC

Revision 1.07 – October 4, 2007

Data Sheet

• External master interface

- Write posting from external master

- Read prefetching on PLB for external master reads

- Bursting capable from external master

- Allows external master access to all non-EBC PLB slaves

- External master can control EBC slaves for own access and control

Ethernet Controller Interface

Ethernet support provided by the PPC440GP interfaces to the physical layer, but the PHY is not included on the

chip.

Features include:

• One or two interfaces running in full- and half-duplex modes at 10Mb/s or 100Mb/s

- One full Media Independent Interface (MII) with 4-bit parallel data transfer

- Two Reduced Media Independent Interfaces (RMII) with 2-bit parallel data transfer

DMA Controller

Features include:

• Supports the following transfers:

- Memory-to-memory transfers

- Buffered peripheral to memory transfers

- Buffered memory to peripheral transfers

• Four channels

• Scatter/Gather capability for programming multiple DMA operations

• 8-, 16-, 32-bit peripheral support (OPB and external)

• 64-bit addressing

• Address increment or decrement

• Supports internal and external peripherals

• Support for memory mapped peripherals

• Support for peripherals running on slower frequency buses

Serial Port

Features include:

• One 8-pin UART and one 4-pin UART interface provided

• Selectable internal or external serial clock to allow wide range of baud rates

• Register compatibility with 16750 register set

• Complete status reporting capability

• Fully programmable serial-interface characteristics

• Supports DMA using internal DMA engine
