12. Dynamic characteristics
[1]
All the timing values are valid within the operating supply voltage and ambient temperature range and refer to VIL and VIH with an input
voltage swing of VSS to VDD.
[2]
tpu(R) and tpu(W) are the delays required from the time VDD is stable until the specied operation can be initiated. These parameters are
guaranteed by design.
[3]
Tcy(W) is the maximum time that the device requires to perform the internal write operation.
