MPC8306S PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 1

Freescale Semiconductor

Electrical Characteristics

– The power management controller detects that the system is not idle and there are

outstanding transactions on the internal bus or an external interrupt.

•

Parallel I/O

— General-purpose I/O (GPIO)

– 56 parallel I/O pins multiplexed on various chip interfaces

– Interrupt capability

•

System timers

— Periodic interrupt timer

— Software watchdog timer

— Eight general-purpose timers

•

Real time clock (RTC) module

— Maintains a one-second count, unique over a period of thousands of years

— Two possible clock sources:

– External RTC clock (RTC_PIT_CLK)

– CSB bus clock

•

IEEE Std. 1149.1™ compliant JTAG boundary scan

Electrical Characteristics

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

MPC8306S. The MPC8306S is currently targeted to these specifications. Some of these specifications are

independent of the I/O cell, but are included for a more complete reference. These are not purely I/O buffer

design specifications.
