Notes:

 

 

 

 

 

 

 

 

 

 

 

1.

Characterized across DC supply voltage range.

 

 

 

 

 

 

 

 

 

2.

Values specified at nominal VCC_CORE . Scale parameters between VCC_CORE. minimum and VCC_CORE. maximum.

 

3.

IOL and IOH are measured at VOL maximum and VOH minimum, respectively.

 

 

 

 

 

4.

Synchronous inputs/outputs are specified with respect to RSTCLK and RSTCK# at the pins.

 

 

 

 

 

5.

These are aggregate numbers.

 

 

 

 

 

 

 

 

 

6.

Edge rates indicate the range over which inputs were characterized.

 

 

 

 

 

 

 

 

7.

In asynchronous operation, the signal must persist for this time to enable capture.

 

 

 

 

 

8.

This value assumes RSTCLK period is 10 ns ==> TBIT = 2*fRST.

 

 

 

 

 

 

 

 

9.

The approximate value for standard case in normal mode operation.

 

 

 

 

 

10.

This value is dependent on RSTCLK frequency, divisors, Low Power mode, and core frequency.

 

 

 

 

 

11.

Reassertions of the signal within this time are not guaranteed to be seen by the core.

 

 

 

 

 

12.

This value assumes that the skew between RSTCLK and K7CLKOUT is much less than one phase.

 

 

 

 

13.

This value assumes RSTCLK and K7CLKOUT are running at the same frequency, though the processor is capable of other

 

 

configurations.

 

 

 

 

 

 

 

 

 

14.

Time to valid is for any open-drain pins. See requirements 7 and 8

in the “Power-Up Timing Requirements“ chapter for more

 

information.
