The STMicroelectronics M48T212V-85MH1E is a 3.3V TIMEKEEPER® supervisor integrated circuit designed for real-time clock applications. This component integrates a real-time clock, power-fail control circuit, battery, and crystal, converting low-power SRAM into NVRAM.
Key features include year 2000 compliance with a 4-digit year display, a battery low flag, microprocessor power-on reset, a programmable alarm output active in battery-backed mode, and a watchdog timer. It also incorporates automatic power-fail chip deselect and write protection.
The device operates with a supply voltage range of 3V to 3.6V and a battery voltage of 3V. The timekeeping current consumption is a maximum of 2mA at 3V to 3.6V. The operating temperature range is from 0°C to 70°C.
This Real Time Clock IC is available in a 44-lead SOIC package and requires a SNAPHAT® top, which must be ordered separately. The interface is parallel, and it supports both time formats HH:MM:SS (24 hr) and date formats YY-MM-DD-dd.
