MPC8280CRUMND 数据手册

Features

— Supports bus snooping for data cache coherency

— Floating-point unit (FPU)

•

Separate power supply for internal logic and for I/O

Separate PLLs for G2_LE core and for the CPM

— G2_LE core and CPM can run at different frequencies for power/performance optimization

— Internal core/bus clock multiplier that provides 2:1, 2.5:1, 3:1, 3.5:1, 4:1, 4.5:1, 5:1, 6:1, 7:1,

8:1 ratios

— Internal CPM/bus clock multiplier that provides 2:1, 2.5:1, 3:1, 3.5:1, 4:1, 5:1, 6:1, 8:1 ratios

64-bit data and 32-bit address 60x bus

•

— Bus supports multiple master designs

— Supports single- and four-beat burst transfers

— 64-, 32-, 16-, and 8-bit port sizes controlled by on-chip memory controller

— Supports data parity or ECC and address parity

32-bit data and 18-bit address local bus

•

— Single-master bus, supports external slaves

— Eight-beat burst transfers

— 32-, 16-, and 8-bit port sizes controlled by on-chip memory controller

60x-to-PCI bridge

— Programmable host bridge and agent

— 32-bit data bus, 66.67/83.3/100 MHz, 3.3 V

— Synchronous and asynchronous 60x and PCI clock modes

— All internal address space available to external PCI host

— DMA for memory block transfers

— PCI-to-60x address remapping

•

PCI bridge

— PCI Speciﬁcation Revision 2.2 compliant and supports frequencies up to 66 MHz

— On-chip arbitration

— Support for PCI-to-60x-memory and 60x-memory-to-PCI streaming

— PCI Host Bridge or Peripheral capabilities

— Includes 4 DMA channels for the following transfers:

– PCI-to-60x to 60x-to-PCI

– 60x-to-PCI to PCI-to-60x

– PCI-to-60x to PCI-to-60x

– 60x-to-PCI to 60x-to-PCI

— Includes all of the conﬁguration registers (which are automatically loaded from the EPROM

and used to conﬁgure the MPC8280) required by the PCI standard as well as message and

doorbell registers

— Supports the I O standard

— Hot-Swap friendly (supports the Hot Swap Speciﬁcation as deﬁned by PICMG 2.1 R1.0

August 3, 1998)
