Microchip Technology MCP795B21T-I-ST is a Real-Time Clock (RTC) IC featuring a clock/calendar function with SPI interface. This component offers 64B of memory, supporting both alarm and watchdog timer functionalities, along with leap year compensation, square wave output, and a unique ID. It operates over a voltage range of 1.8V to 5.5V for the main supply and 1.3V to 5.5V for battery backup, with a low timekeeping current of 1µA at 1.8V. The time format is configurable to HH:MM:SS:hh (12/24 hr) and the date format to YY-MM-DD-dd. The device is housed in a 14-TSSOP package and is supplied on tape and reel. Applications include industrial automation, consumer electronics, and medical devices.
