    LISA-U series - System Integration Manual Power management 1.5.1 Power supply circuit overview LISA-U series modules feature a power management concept optimized for the most efficient use of supplied power. This is achieved by hardware design utilizing a power efficient circuit topology (Figure 4), and by power management software controlling the module’s power saving mode.

    LISA-U series - System Integration Manual The VCC pins are directly connected to the RF power amplifiers and to the integrated Power Management Unit (PMU) within the module: all supply voltages needed by the module are generated from the VCC supply by integrated voltage regulators.
  • Page 22 LISA-U series - System Integration Manual When LISA-U series modules are in operation, the voltage provided to VCC pins can go outside the normal operating range limits but must be within the extended operating range limits specified in LISA-U1 series Data Sheet [1] and LISA-U2 series Data Sheet [2].

  • Page 28 LISA-U series - System Integration Manual Additional recommendations for the VCC supply application circuits To reduce voltage drops, use a low impedance power source. The resistance of the power supply lines (connected to the VCC and GND pins of the module) on the application board and battery pack should also be considered and minimized: cabling and routing must be as short as possible in order to minimize power losses.
  • Page 29 LISA-U series - System Integration Manual External battery charging application circuit LISA-U series modules do not have an on-board charging circuit. An example of a battery charger design, suitable for applications that are battery powered with a Li-Ion (or Li-Polymer) cell, is provided in Figure 11. In the application circuit, a rechargeable Li-Ion (or Li-Polymer) battery cell, that features proper pulse and DC discharge current capabilities and proper DC series resistance, is directly connected to the VCC supply input of LISA-U series module.

  • Page 30: Current Consumption Profiles

    LISA-U series - System Integration Manual 1.5.3 Current consumption profiles During operation, the current drawn by the LISA-U series modules through the VCC pins can vary by several orders of magnitude. This ranges from the high peak of current consumption during GSM transmitting bursts at maximum power level in 2G connected mode, to continuous high current drawn in UMTS connected mode, to the low current consumption during power saving in idle-mode.

This happens for 2.307 ms (width of the 4 transmit slots/bursts) with a periodicity of 4.615 ms (width of 1 frame = 8 slots/bursts), so with a 1/2 duty cycle, according to GSM TDMA. If the module is in GPRS connected mode in the DCS 1800 or in the PCS 1900 band, the current consumption figures are lower than in the GSM 850 or in the E-GSM 900 band, due to 3GPP transmitter output power specifications (see LISA-U1 series Data Sheet [1] and LISA-U2 series Data Sheet [2]).
  • Page 32 LISA-U series - System Integration Manual 1.5.3.2 3G connected mode During a 3G connection, the module can transmit and receive continuously due to the Frequency Division Duplex (FDD) mode of operation with the Wideband Code Division Multiple Access (WCDMA). The current consumption depends again on output RF power, which is always regulated by network commands.

When power saving is enabled, the module automatically enters idle-mode whenever possible.
  • Page 34 LISA-U series - System Integration Manual 1.5.3.4 2G and 3G fixed active mode (power saving disabled) Power saving configuration is by default disabled, or it can be disabled using the appropriate AT command (see the u-blox AT Commands Manual [3], AT+UPSV command). When power saving is disabled, the module does not automatically enter idle-mode whenever possible: the module remains in active mode.

    LISA-U series - System Integration Manual 1.5.4 RTC Supply (V_BCKP) The V_BCKP pin connects the supply for the Real Time Clock (RTC) and Power-On / Reset internal logic. This supply domain is internally generated by a linear regulator integrated in the Power Management Unit. The output of this linear regulator is always enabled when the main voltage supply provided to the module through VCC is within the valid operating range, with the module switched-off or powered-on.
  • Page 36 LISA-U series - System Integration Manual The internal regulator for V_BCKP is optimized for low leakage current and very light loads. It is not recommended to use V_BCKP to supply external loads. If V_BCKP is left unconnected and the module main voltage supply is removed from VCC, the RTC is supplied from the bypass capacitor mounted inside the module.

The purpose of the series resistor is to limit the battery charging current due to the battery specifications, and also to allow a fast rise time of the voltage value at the V_BCKP pin after the VCC supply has been provided.

    LISA-U series - System Integration Manual 1.9.4 SPI interface SPI is a master-slave protocol: the module runs as an SPI slave, i.e. it accepts AT commands on its SPI interface without specific configuration. The SPI-compatible synchronous serial interface cannot be used for FW upgrade. The standard 3-wire SPI interface includes two signals to transmit and receive data (SPI_MOSI and SPI_MISO) and a clock signal (SPI_SCLK).

The SPI-device shall look for all upper-SW-layers like any other serial device. This means that LISA-U modules emulate all serial logical lines: the transmission and the reception of the data are similar to an asynchronous device.

The master does not need to de-assert SPI_MRDY as it controls the SPI_SCLK 5. After the preparation, the slave activates again SPI_SRDY and wait for SPI_SCLK activation. When the clock is active, all data is transferred without intervention.

It is recommended to tri-state the output pins of the SPI Master (i.e. set in high impedance mode) when LISA-U module is in power-down mode, when the external reset is forced low and during the module power-on sequence (at least for 3 s after the start-up event), to avoid latch-up of circuits and allow a proper boot of the module.
