■ VT-200-FL (Cylinder-type low CL resonator for low-power microcontrollers)
The VT-200-FL is a cylinder-type resonator specially developed and released for ultra-low-power microcontrollers.
Through collaboration with major microcontroller manufacturers, we achieved low power consumption.
Please visit the SII website (www.sii-crystal.com) for finding microcontrollers for VT-200-FL.
CAUTION
The VT-200-FL is designed for use in ultra-low-power microcontrollers. Do not use this resonator in regular
microcontrollers as it might cause problems with oscillation.
