Check the application circuit of pin 52. This pin is Reserved (
RSVD
) on LISA-C200, as it is on LISA-U1
series modules. On LISA-U230 and LISA-U200 modules, it provides clock output (
CODEC_CLK)
.
Check the application circuit of pins 20, 21, 23, 24, and 51. LISA-C200 provides GPIOs, as do LISA-U
series modules, but LISA-U series modules provide additional functionalities.
Check the application circuit of the SIM interface pins. Upon request to u-blox, LISA-C200 can support
an external SIM (RUIM) card.
Check the application circuit of pin 74. This pin is Reserved (
RSVD
) on LISA-C200, as it is on LISA-U1
series and LISA-U200. On LISA-U230, it provides RF input for Rx diversity antenna (
ANT_DIV
).
Check the application circuit of the
ANT
pin. An antenna circuit properly designed for LISA-U series
modules is compatible for LISA-C200, because LISA-C200 transmits and receives on a subset of the
frequencies used by LISA-U series modules.
Check the temperature requirements. The LISA-C200 operating temperature range (refer to
LISA-C2
series Data Sheet
[1]) is comparable to that of the LISA-U series modules, but LISA-C200 doesn’t support
embedded Smart Temperature Supervisor as LISA-U series modules do.
Check the board layout, since some signal keep-out areas must be implemented on the top layer of the
application board, below LISA-U modules, due to GND opening on the module bottom layer.
See the “Hardware migration” section in this appendix for further details.
Check LISA-C200 series software requirements
Check the AT commands supported by LISA-C200 via UART and USB serial interfaces, including Carrier
AT commands, Industry standard AT commands and u-blox AT Commands (for the complete list refer to
u-blox LISA-C200 Commands Manual [3]).
Check the LISA-C200 firmware upgrade capabilities. Firmware can be upgraded by USB interface, but
cannot be upgraded by UART interface.
Check the power-on and reset timings. LISA-U series modules differ from LISA-C200 modules (refer to
LISA-C2 series Data Sheet
Check the difference in the power-on sequence by reviewing the LISA-C2 power management section
(see section 1.5) and the LISA-U2 series power management section (see the
LISA-U2 series System
Integration Manual
[4]). Make sure the different power-on sequence complies to the specific module’s
requirements.
One important difference between the LISA-C200 and LISA-U series power-on sequence is that for the
LISA-C200, the RESET_N pin must be left alone (not driven externally) during the boot-up sequence.
Check the following functionalities that are not supported by LISA-C200:
o
V_BCKP
supply for Real Time Clock
o
DSR
,
DCD
and
DTR
signals of the UART interface
o
SPI interface
o
DDC (I2C) interface for the integration with u-blox GPS receivers
*
o
Jamming detection
o
Smart Temperature Management
o
Embedded SSL
o
In-Band modem
*
DDC(I
2
C) interface is supported only by LISA-C200-03S/23S and successive versions
If applicable, check the following functionality that is supported upon request by LISA-C200:
o
External SIM (RUIM)
