SII Semiconductor Corporation, a subsidiary of Seiko Instruments Inc. introduces the new S-35710M built-in 32.768kHz quartz crystal convenience timer for automotive applications. The S-35710M exhibits very low current consumption as compared to the implementation of the embedded microcontroller timer functions. The S-35710M is suitable for management of relative time*1 and reduces system standby current.
The S-35710M is a 2-in-1*2 timer product with an IC and Quartz Crystal built into a single package reducing the number of external components and producing an accurately matched Oscillator and Crystal.
The S-35710M is suitable for time management during system sleep periods*3 after engine shut-down. The alarm time can be programmed in one-second increments from one second to 194 days. Using this timer with its ultra-low current consumption of only 250nA typical, reduces the system standby current.
Influenced by fuel evaporative emission regulations, including EURO 6*4 (Europe), demand for periodic status management during engine shut-down is critical. In addition, blank detection capability is required for electric vehicles to monitor the status of the battery when it is not in use or while charging.
The S-35710M comes in a lead-free and halogen-free 8-pin HSOP-8Q package.
*1 Relative time: The time interval from the time when an event occurs: e.g. “output an interrupt signal at xx minutes after the MCU stops.”
In contrast, absolute time denotes clock time: e.g. “Output an interrupt signal at xx:xx AM/PM every day.”
*2 2-in-1： A type of package that is made up from two components (a timer IC and a Quartz Crystal).
*3 During system sleep period： The period while the electronic control unit (ECU) is in sleep mode (power saving mode).
*4 EURO 6: European regulations that define the emission regulatory values of air pollutants from automobiles, which includes the fuel evaporative emission regulations.
To manage these values, time measurement during engine shut-down is important.
