The M48T37V-10MH6F is a real-time clock (RTC) integrated circuit that operates at a supply voltage of 3.0 to 3.6 V. It features 256 Kbit of TIMEKEEPER® SRAM, which is organized as 32 Kbit x 8. This product includes an ultra-low power SRAM, a real-time clock, a power-fail control circuit, and a battery backup system. It also offers a frequency test output for software calibration of the real-time clock. Key functionalities include automatic power-fail chip deselect and WRITE protection, a watchdog timer, and a programmable alarm output that remains active during battery backup mode. The device is packaged in a 44-lead SOIC format and requires a SNAPHAT® top for the battery and crystal, which must be ordered separately. The M48T37V is RoHS compliant, ensuring it meets environmental regulations. This product is suitable for applications requiring reliable timekeeping and data retention during power interruptions.
