nPrecautions Concerning Use
(1) Notes on the XALM function
When not maintained by the back-up power supply, at initial power on the XIRQ state is indeterminate.
- XIRQ is not affected by RESET or other signals, nor by any of the RTC functions.
XIRQ goes active immediately the alarm conditions are met, even if in the back-up power state.
The extended alarm data mode must be set the same as the RTC data mode. (24/12 hour setting, and
BCD/binary data format)
° The XALM pin has an internal pull-up resistor, so if XALM and XIRQ are left open-circuit, the extended alarm
functions will be completely ignored.
(2) In order to achieve low power consumption in the oscillator section of the RTC-65 series, high impedance is used.
Since the shaded portion of the diagram is highly inductive, do not put signal wires into close proximity of the shaded
portion.
(3) Bypass capacitor:
In order to provide for stable operation (i.e., to prevent interruptions and noise), install a 0.01
F or more bypass
capacitor close to the RTC.
(4) Although the device is resistant to impact up to the point of being dropped on a hard wooden board from 75cm, there
is a chance that the resonator may be damaged during assembly by inserter equipment, etc., depending on the
machine and other conditions. Therefore, please confirm that the equipment to be used is safe for this device before
putting it into service.
In addition, be sure to reconfirm the safety of the equipment if any of the mounting conditions are changed at a later
point in time.
