UBX-13001118 - R25 Appendix Page 168 of 182
PWR_ON low pulse time required to switch on the module is different in comparison to LISA-U1 series
modules.
LISA-U2 series can be switched off forcing PWR_ON pin to the low level for at least 1 second.
PWR_ON and RESET_N input voltage thresholds are slightly changed in comparison to LISA-U1 series
modules, but this is not relevant driving PWR_ON and RESET_N inputs by open drain / collector
drivers as recommended.
V_BCKP operating characteristics are slightly changed in comparison to LISA-U1 series modules.
The voltage level of all the digital interfaces of LISA-U2 series modules is 1.8 V as for LISA-U1 series
modules.
The internal active pull-up / pull-down values at the digital interface input pins and the current
capability of digital interface output pins LISA-U2 series modules are slightly changed in comparison
to LISA-U1 series modules.
UART of LISA-U2 series supports autobauding (default setting) and 921600 bit/s baud rate.
LISA-U2 series provide one additional USB CDC for the remote SIM Access Profile (SAP).
The 5 pins of the SPI / IPC Serial Interface can be configured as GPIOs on LISA-U2 series.
The DDC (I
2
C) interface of LISA-U2 series modules can be used to communicate with u-blox GNSS
receivers and at the same time to control an external audio codec. The LISA-U2 series module acts as
an I
2
C master which can communicate to two I
2
C slaves as permitted by the I
2
C bus specifications [8].
LISA-U2 modules provide additional GPIO functions: Module Status and Operating Mode Indications.
LISA-U2 modules are SMT modules and share the same compact form factor as the LISA-U1 series,
featuring Leadless Chip Carrier (LCC) packaging technology.
An additional signal keep-out area must be implemented on the top layer of the application board,
below LISA-U2 modules, due to the GND opening on the module bottom layer.
Detailed pinout and layout comparisons between LISA-U1 series and LISA-U2 series modules, with
remarks for migration, are provided in subsections A.3.2 and A.3.3.
