Frequency selectable clock output ( 32.768 kHz to 1/30 Hz )
Built-in 30 second adjustment function, digital pace adjustment function (max. adjustment: ±192 × 10-6)
Built-in alarm and timer interrupt functions
Built-in semiconductor temperature sensor ( Voltage output: -7.8 mV / °C , RTC-7301SF )
Operating voltage range: 2.4 V to 5.5 V, timekeeper (retained) voltage range: 1.6 V to 5.5 V
Low current consumption (0.6 A / 3V Typ.)
High speed parallel interface compatible with S-RAM
1. Overview
This is a real-time clock module using a parallel interface method with a built-in crystal oscillator.
It has a variety of built-in functions such as the leap year Clock & Calendar circuit that automatically adjust from
seconds to years, the alarm and timer interrupt functions, and the time update detector.
It is also equipped with a
frequency selectable clock output pin.
Furthermore, it has a digital pace adjustment function for adjusting the accuracy of the clock and a semiconductor
temperature sensor (analog voltage output) to enable a more accurate clock system.
Also, the interface employed is a parallel interface that is compatible with S-RAM thereby making connections
easier and high speed data communication possible.
We have both SSOP and DIP package types enabling this to be used on a wide range of electronic equipment such
as computers, word processors, facsimiles, multi-function telephones, sequencers and various types of control
equipment.

* This is a block diagram for RTC-7301SF.
Be aware that RTC-7301DG differs according to the following 2 points.
1) The VTEMP output is not connected to an external pin.
2) The FCON input pin is not connected to an external pin, but is fixed at “H” internally.
