9TCS1082 Datasheet | Renesas

Description Features The 9TCS1082 is a highly programmable IC that integrates clock synthesizers and a temperature sensor for hardware thermal protection. The device has an ultra-low-power 32.768 k Hz frequency generator to support Real Time Clocks (RTC). This device can generate the 32.768 k Hz frequency up to four years of life powered by a CR2032 coin cell battery. The 9TCS1082 can output puter system clock frequencies of 25, 27, and 48 MHz which will reduce the ponent count on the circuit board. The 9TCS1082 includes temperature monitor function that measures through external diode. The temperature sensor is optimized to be accurate within ±1°C between 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 setting critical limits. The hardware limits drive dedicated Alert and Therm pins for system shutdown. The 9TCS1082 is available in a 32-pin QFN package and is available for mercial temperature range Applications - Notebook puters - Netbook puters - Smartbook puters - Consumer Portable Devices - Embedded Systems - Networking Equipment (i.e. Routers, Switches) - Network Area Storage Thermal Sensor - One channel thermal sensor - Both H/W & S/W programmable over/under temperature alarms - No Calibration required in application - Diode failure detection - Support SMBUS Alert - Accuracy: ±1°C (+60°C to +100°C, remote); ±2°C (0°C to + 100°C, remote and local) - Offset register for system calibration - Series resistor cancellation feature System Clock PLL Synthesizers - Scalable Low Voltage VDD I/O (1.5V to 1.05V) to reduce power consumption (apply to 25MHz output) - Integrated series termination resistors - Selectable - Single-ended 27MHz/48MHz clock output @ VDD3.3V - 2 - single ended 25MHz clock outputs (buffer out) - 32.768 k Hz outputs with < 1.8µA power consumption for system RTC circuit IDT® MOBILE ACCESS™- CLOCK SYNTHESIZER & TEMPERATURE SENSOR...
