SLG3NB3331
32.768 kHz and MHz
GreenCLK
General Description
The SLG3NB3331 uses a 25 MHz Reference Crystal to pro-
vide one 32.768 kHz clock output and three 25 MHz clock
outputs. The part supports a non-rechargeable coin cell bat-
tery (ex. CR2032) as the power source for the ultra low power
Hibernate mode operation.
Features
• 32.768 kHz GreenCLK technology for RTC
• Scalable VIO
• Improved performance over temperature
• Supports Industrial temperature range
• Smaller package and layout foot print
• 16-pin TQFN: 2 x 3 x 0.75 mm, 0.4 mm pitch
• Pb-Free / Halogen-Free / RoHS compliant
Output Summary
• 1x 32.768 kHz clock output (1.8 μA in Hibernate Mode)
• 3x 25 MHz clock outputs (2.5 mA in Active Mode)
