The M48T37V-10MH6E 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 ultra-low power, making it suitable for battery-backed applications. The device includes a power-fail control circuit, automatic chip deselect, and WRITE protection to ensure data integrity during power interruptions. Additionally, it offers a frequency test output for software calibration of the real-time clock, a programmable alarm output that remains active during battery backup, and a battery low flag for monitoring battery status. The M48T37V is packaged in a 44-lead SOIC format and requires a SNAPHAT® top for the battery and crystal, which must be ordered separately. The product is RoHS compliant, ensuring it meets environmental standards.
