Module sleep Module will automatically go into sleep mode when there is
no interrupt input or other operation.
In this case, the current consumption of module will be
reduced to the minimal level.
GSM IDLE Software is active. Module has registered to the GSM network,
and the module is ready to send and receive.
GSM mode
GSM TALK CSD connection is going on between two subscribers. In this
case, the power consumption depends on network settings
such as DTX off/on, FR/EFR/HR, hopping sequences,
antenna.
GPRS IDLE Module is ready for GPRS data transfer, but no data is
currently sent or received. In this case, power consumption
depends on network settings and GPRS configuration (e.g.
multi-slot settings).
GPRS mode
GPRS DATA There is GPRS data in transfer (PPP or TCP or UDP). In this
case, power consumption is related with network settings (e.g.
power control level), uplink/downlink data rates and GPRS
configuration (e.g. used multi-slot settings).
EDGE mode EDGE IDLE Module is ready for data transfer in EDGE mode, but no data
is currently sent or received. In this case, power consumption
depends on network settings and EDGE configuration
EDGE mode EDGE DATA There is data in transfer (PPP or TCP or UDP) in EDGE mode.
In this case, power consumption is related with network
settings (e.g. power control level), uplink/downlink data rates
and EDGE configuration.
WCDMA
IDLE
Module has registered to the WCDMA network, and the
module is ready to send and receive.
WCDMA mode
WCDMA talk Module is active in WCDMA mode. The power consumption
depends on network settings.
POWER DOWN Normal shutdown is by sending the “AT+CPOF” command or using the
POWER_ON pin. The power management ASIC disconnects the power supply
from the base band part of the module, only the power supply for the RTC is
remained. Software is not active. The serial interfaces are not accessible.
Operating voltage (connected to VBAT) remains applied.
Minimum
functionality mode
(flight mode)
Use of the “AT+CFUN” command can set the module to a minimum
functionality mode without remove the power supply. In this case, disable phone
both transmit and receive RF circuits, that is to say ,flight mode
3.3 Power supply
The power supply of SIM5216A is from a single voltage source of VBAT= 3.3V...4.2V. In
some cases, the ripple in a transmit burst may cause voltage drops when current consumption
rise typically to peak of 2A. So the power supply must be able to provide sufficient current
up to 2A.
For the VBAT input, a local bypass capacitor is recommended. A capacitor (about 100µF, low
