Clock
Accuracy
*3
*3. The ST’s internal clock has a slight error. At normal operating temperatures and conditions,
with the ST operating from its lithium battery, the degree of error is 65 seconds per month.
Variations in operating conditions and battery life can cause this error to vary from -380 to +90
seconds per month. For systems where this degree of error will be a problem, the user should
be sure to monitor this error and make adjustments when required.
±65 seconds/ month (at room temperature)
