Temp Sensor Digital Serial (I2C) 32-Pin VFQFPN T/R

The 9TCS1082 is a highly programmable IC that integrates clock synthesizers and multiple temperature sensors for hardware thermal protection. The device has an ultra-low-power 32.768 kHz frequency generator to support Real Time Clocks (RTC). This device can generate the 32.768 kHz frequency up to four years powered by a CR2032 battery. The 9TCS1082 can output computer system clock frequencies of 25, 27, and 48 MHz which will reduce the component count on the circuit board. The device is highly configurable through I2C for ease and flexibility of use. The 9TCS1082 includes a temperature monitor. The temperature sensor is optimized to be accurate within ±1°C within the temperature range of 60°C to 100°C. This device is highly programmable through the use of I2C to set high and low limits for all the temperature channels as well as set critical limits. The hardware limits drive dedicated fault and alert pins for system shutdown. The 9TCS1082 is available in a 32-pin QFN package and is available for commercial temperature range.
