Through collaboration with major microcontroller manufacturers, we achieved low power consumption resonator. Please visit the SII website (www.sii-crystal.com) for finding microcontrollers for SSP-T7-FL. CAUTION The SSP-T7-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. www.sii-crystal.com Quartz Crystal 2011
