Pinout
The primary function of the M4T32-BR12SH6 is to provide backup power and timing reference to RTCs, ensuring the preservation of timekeeping and RAM data during a main power failure. The lithium battery provides long-term power, while the integrated crystal maintains accurate timekeeping.
Here is a concise breakdown of its pin functions:
1. VCC (Pin 1): Connects to the VCC of the TIMEKEEPER® device for main power input.
2. VBAT (Pin 2): Connects to the battery input of the TIMEKEEPER® device, providing backup power.
3. GND (Pin 3): Ground connection.
4. Crystal (Pin 4): Connects to the crystal input of the TIMEKEEPER® device, providing the oscillation necessary for timekeeping.
This setup ensures that the connected RTC maintains accurate time and data retention even when the main system is powered off.
