Power Down Mode
The FDL01TU has three power down modes. Select the mode according to the power
supply operating conditions such as battery powered application.
(1) Active Mode
This mode is not the power down mode but always capable of transmitting and receiving
data. The modem is in the active mode when the power is turned on.
The current consumption is 110 mA maximum in this mode.
(2) RF Block Power Down Mode
This mode shuts down the power supply of the RF circuit block, where only the control
(logic) circuit is activating. Since the control circuit is in operation, the setting of
memory
registers
are retained. When the modem returns to the
Active mode
, it can continue its
operation since the register value is retained. Furthermore, functions such as referencing
and setting memory registers can be used in this mode.
This mode is invoked by the following commands.
ROF command
: to become the
RF block power down mode
RON command
: to return to the
Active mode
The current consumption is about 35 mA in this mode.
