MPC826xA (HiP4) Family Hardware Specifications
MOTOROLA
Electrical and Thermal Characteristics
– Internal rate mode (sub-rate)—FCC transfers only the data cells using the required data rate.
The TC layer generates idle/unassigned cells to maintain the line bit rate.
— Supports TC-layer and PMD-WIRE interface (according to the ATM-Forum af-phy-0063.000)
— Cell counters for performance monitoring
– 16-bit counters count
– HEC error cells
– HEC single bit error and corrected cells
– Idle/unassigned cells filtered
– Idle/unassigned cells transmitted
– Transmitted ATM cells
– Received ATM cells
– Maskable interrupt is sent to the host when a counter expires
— Overrun (Rx cell FIFO) and underrun (Tx cell FIFO) condition produces maskable interrupt
— May be operated at E1 and DS-1 rates. In addition, xDSL applications at bit rates up to 10 Mbps
are supported
PCI bridge (MPC8265 and MPC8266 only)
— 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 Periphera
l
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 MPC8265) required by the PCI standard as well as message and
doorbell registers
— Supports the I
2
O standard
— Hot-Swap friendly (supports the Hot Swap Specification as defined by PICMG 2.1 R1.0
August 3, 1998)
— Support for 66 MHz, 3.3 V specification
— 60x-PCI bus core logic which uses a buffer pool to allocate buffers for each port
— Makes use of the local bus signals, so there is no need for additional pins
