SC200L supports (U)SIM card hot-plug via the USIM_DET pin. A reference circuit for (U)SIM interface
with an 8-pin (U)SIM card connector is shown below.
Figure 14: Reference Circuit for (U)SIM Interface with an 8-pin (U)SIM Card Connector
If there is no need to use USIM_DET, please keep this pin open. The following is a reference circuit for
(U)SIM interface with a 6-pin (U)SIM card connector.
USIM2_VDD 21 PO
(U)SIM2 card power
supply
Either 1.8V or 2.95V (U)SIM card is
supported.
USIM1_DET 22 DI
(U)SIM1 card plug
detection
Active Low. If it is not used, keep it
open.Enabled by default via
software.It can be multiplexed into
a generic GPIO.
USIM1_RST 23 DO
(U)SIM1 card reset
signal
It cannot be multiplexed into a
generic GPIO.
USIM1_CLK 24 DO
(U)SIM1 card clock
signal
It cannot be multiplexed into a
generic GPIO.
USIM1_DATA 25 IO
(U)SIM1 card data
signal
It cannot be multiplexed into a
generic GPIO.
USIM1_VDD 26 PO
(U)SIM1 card power
supply
Either 1.8V or 2.95V (U)SIM card is
supported.
