Table 4: Power state transition levels
Wireless CPU Power status SIMDET level
Power ON >1.5V
Power OFF <0.4V
It is possible to connect the SIMDET-signal directly to the Application
processor, but the integrator must ensure that no voltage is applied
onto SIMDET (through pull-up resistors etc.). The Wireless CPU might
malfunction If the application applies a voltage level onto SIMDET after
the Wireless CPU has been powered down.
CAUTION
If the application supports SIM removal HW-detection, the SIMDET must
be used to detect the SIM availability status to pass the type approval.
HW-detection of the power state will in this case not be possible. The
affected test cases are:
• 26.2.2 -p2 - GSM Protocol
• 26.7.4.2.4 p5 - GSM Protocol
• 31.6.2.1 - Supplementary Services
• 44.2.3.1.4 - GRPS Protocol
These test cases may not pass the certification tests without the SIM
detect line enabled, and PICS/PIXIT 3GPP TS 51010-1 A.25/40 set to
Supported. Currently, the GR64 and GS64 products do not support SIM
removal without power down, so A.25/40 is set to Not Supported which
allows these test cases to pass.
