ing a power failure. If the power failure extends
the life of the battery, the microcontroller should
perform the initialization sequence (as described
on page 2-4), and use the SETD command to set
the date and time.
To keep power consumption low during power-
down mode, the RESET, MWCS, MWCLK and
MWDIN signals should be held above V

POWER AND GROUNDING
Power Pin Connections
The ISD-T360 can operate over two supply volt-
age ranges 3.3 V ±10% and 5 V ±10%. The five
power supply pins (V

Figure 1-5 when operating in a 3.3 V environ-
ment, and as shown in Figure 1-6 when operat-
ing in a 5 V environment. Failure to correctly
connect the pins may result in damage to the
device.
The Capacitor and Resistor values are given in
Table 1-3.

All capacitors represent two parallel capacitors at
the values 1.0 μF and 0.1 μF.
