MPC8260A PowerQUICC™ II Integrated Communications Processor Hardware Specifications, Rev. 1.1

Freescale Semiconductor

Electrical and Thermal Characteristics

— 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

Electrical and Thermal Characteristics

This section provides AC and DC electrical specifications and thermal characteristics for the MPC826xA.

2.1

DC Electrical Characteristics

This section describes the DC electrical characteristics for the MPC826xA. Table 1 shows the maximum

electrical ratings.

Table 1. Absolute Maximum Ratings(1)

Notes:

1. Absolute maximum ratings are stress ratings only; functional operation (see Table 2) at the maximums is not

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