DDR memory module temp sensor with integrated SPD
 
[1]   Minimum clock frequency is 0 kHz if SMBus Timeout is disabled.
[2]   Delay from SDA STOP to SDA START.
[3]   A device must internally provide a hold time of at least 200 ns for SDA signal (referenced to the V
IH(min)
 of the SCL signal) to bridge the
undefined region of the falling edge of SCL.
[4]   Delay from SCL HIGH-to-LOW transition to SDA edges.
[5]   Delay from SCL LOW-to-HIGH transition to restart SDA.
[6]   Delay from SDA START to first SCL HIGH-to-LOW transition.
[7]   These parameters tested initially and after a design or process change that affects the parameter.
[8]   t
pu(R)
 and t
pu(W)
 are the delays required from the time V
DD
 is stable until the specified operation can be initiated.

= 40 ?/SPAN>C to +125 ?/SPAN>C; unless otherwise specified. These specifications are guaranteed by design.
The AC specifications fully meet or exceed SMBus 2.0 specifications, but allow the bus to interface with the I
