5V PC REAL TIME CLOCK
The M48T86PC is a real-time clock (RTC) IC manufactured by STMicroelectronics. It is a low-power CMOS device that provides a full binary coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM.
Description:
The M48T86PC is a low-power CMOS Real-Time Clock (RTC) and calendar. It provides a full binary coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator.
