MOTOROLA
MPC8280 PowerQUICC II Family Hardware Specications
5
Overview
— Support for 66.67/83.33/100 MHz, 3.3 V specication
— 60x-PCI bus core logic that uses a buffer pool to allocate buffers for each port
— Uses the local bus signals, removing need for additional pins
System interface unit (SIU)
— Clock synthesizer
— Reset controller
— Real-time clock (RTC) register
— Periodic interrupt timer
— Hardware bus monitor and software watchdog timer
— IEEE 1149.1 JTAG test access port
12-bank memory controller
— Glueless interface to SRAM, page mode SDRAM, DRAM, EPROM, Flash and other user-
denable peripherals
— Byte write enables and selectable parity generation
— 32-bit address decodes with programmable bank size
— Three user-programmable machines, general-purpose chip-select machine, and page-mode
pipeline SDRAM machine
— Byte selects for 64-bus width (60x) and byte selects for 32-bus width (local)
— Dedicated interface logic for SDRAM
CPU core can be disabled and the device can be used in slave mode to an external core
Communications processor module (CPM)
— Embedded 32-bit communications processor (CP) uses a RISC architecture for exible support
for communications protocols
— Interfaces to G2_LE core through an on-chip 32-Kbyte dual-port data RAM, an on-chip
32-Kbyte dual-port instruction RAM and DMA controller
— Serial DMA channels for receive and transmit on all serial channels
— Parallel I/O registers with open-drain and interrupt capability
— Virtual DMA functionality executing memory-to-memory and memory-to-I/O transfers
— Three fast communications controllers supporting the following protocols:
– 10/100-Mbit Ethernet/IEEE 802.3 CDMA/CS interface through media independent
interface (MII) or reduced media independent interface (RMII)
– ATM—Full-duplex SAR protocols at 155 Mbps, through UTOPIA interface, AAL5, AAL1,
AAL0 protocols, TM 4.0 CBR, VBR, UBR, ABR trafc types, up to 64 K external
connections (no ATM support for the MPC8270)
– Transparent
– HDLC—Up to T3 rates (clear channel)
– FCC2 can also be connected to the TC layer (MPC8280 only)
— Two multichannel controllers (MCCs) (one MCC on the MPC8270)
– Each MCC handles 128 serial, full-duplex, 64-Kbps data channels. Each MCC can be split
into four subgroups of 32 channels each.
– Almost any combination of subgroups can be multiplexed to single or multiple TDM
interfaces up to four TDM interfaces per MCC
