MPC8272 PowerQUICC II Family Hardware Specifications, Rev. 3

Freescale Semiconductor

Operating Conditions

•

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 four 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 the configuration registers required by the PCI standard (which are automatically

loaded from the EPROM to configure the MPC8272) and message and doorbell registers

— Supports the I2O 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

Operating Conditions

This table shows the maximum electrical ratings.

Table 3. Absolute Maximum Ratings1

1 Absolute maximum ratings are stress ratings only; functional operation (see Table 4) at the maximums is not

guaranteed. Stress beyond those listed may affect device reliability or cause permanent damage.

2 Caution: VDD/VCCSYN must not exceed VDDH by more than 0.4 V during normal operation. It is recommended that

VDD/VCCSYN should be raised before or simultaneous with VDDH during power-on reset. VDD/VCCSYN may

exceed VDDH by more than 0.4 V during power-on reset for no more than 100 ms.
