EPSON X1B000142000212, Real Time Clock Serial-I2C

RX-8803 high stability SMD real time clock modules with a built in frequency adjusted 32.768 kHz crystal unit and DTCXO. The devices in this module are fabricated via a C-MOS process for low current consumption, enabling long term battery back-up. These RX-8803 real time clock modules have a 1/100s resolution time register, an I²C Bus interface, an interface voltage range of 1.6V to 5.5V, a temperature compensated voltage range of 2.2V to 5.5V, a clock supply voltage range of 1.6V to 5.5V and a selectable clock output of 32.768 kHz, 1024 Hz, 1 Hz. The functions of these RX-4803 real time clock modules include calendar, alarm, timer and EVIN input.
