Frequently Asked Questions
What is the operating temperature range?
−40 to +85 °C.
How do I set the hours?
Close switch S1 to increment hours based on the correction mode set by switch S6.
What display modes are available?
12-hour or 24-hour display mode, selectable by connecting switch S5 to VDD or VSS.
How does the ±2 minute correction work?
Pressing S3 resets minutes and seconds to zero; if displayed time is ≥58 min, the hour increments by one.
What package options exist?
40-lead plastic SMD face down (VSO40) or uncased chip in tray.
