71M6513 Maxim, 71M6513 Datasheet - Page 83

• Manufacturer Part Number: 71M6513
• Description: The 71M6513 and 71M6513H are highly integrated SoCs with an MPU core, RTC, flash, and LCD driver
• Manufacturer: Maxim

The oscillator drives a standard 32.768 kHz watch crystal. The oscillator has been designed specifically to handle these
crystals and is compatible with their high impedance and limited power handling capability. The oscillator power dissipation is
very low to maximize the lifetime of any battery backup device attached to VBAT.
Board layouts with minimum capacitance from XIN to XOUT will require less battery current. Good layouts will have XIN and
XOUT shielded from each other.
