The STMicroelectronics M48T212V-85MH1F is a 3.3V TIMEKEEPER® supervisor designed to convert low-power SRAM into NVRAMs. This integrated real-time clock (RTC) supervisor includes a power-fail control circuit, battery, and crystal. It offers features such as a year 2000 compliant 4-digit year display, a battery low flag, and a microprocessor power-on reset.
Key electrical specifications include an operating voltage range of 3V to 3.6V and a timekeeping current of 2mA at 3V-3.6V. The device supports a parallel interface and operates within a temperature range of 0°C to 70°C. It also features a programmable alarm output active in battery-backed mode and a watchdog timer.
The M48T212V-85MH1F is available in a 44-lead SOIC package (SOH44) and requires a SNAPHAT® top, which must be ordered separately. It supports automatic power-fail chip deselect and WRITE protection, with a power-fail deselect voltage between 2.7V and 3.0V. The component is RoHS compliant with lead-free second-level interconnects.
