Power Down Sequence

Power down sequence for SIM interface is as follows:

•

SIMx_SIMPDy port detects the removal of the SIM Card

•

SIMx_RSTy goes Low

•

SIMx_CLKy goes Low

•

SIMx_DATAy_RX_TX goes Low

•

SIMx_SVENy goes Low

Each of these steps is done in one CKIL period (usually 32 kHz). Power-down can be started because of a

SIM Card removal detection or launched by the processor. Find in the table and figure below the usual

timing requirements for this sequence, with Fckil = CKIL frequency value.
