Features Benefits
  • Factory programmable from 32.768 kHz down to 1 Hz
  • Significantly reduces power compared to fixed 32.768 kHz XTAL
  • Smallest footrpint in chip-scale (CSP):
    1.5 x 0.8mm
  • Saves board space by up to 85% compared to the 2012 SMD
  • Small SMD package: 2.0 x 1.2mm (2012)
  • Pin-compatible to 2012 XTAL SMD
  • Ultra-low power: 750nA (typ)
  • Extends battery life
  • Low or high supply voltage operation
  • 1.2 to 3.63V supports coin-cell or supercap battery backup
  • 2.7 to 4.5V optimized to operate directly from an unregulated Li+ battery
  • NanoDrive™ reduced swing oscillator output
  • Directly interfaces to MCU/PMIC/chipset XTAL IN
