Smartcard
The smartcard interface chip is used on the STM3210E-EVAL board for asynchronous 3
and 5 V smartcards. It performs all supply protection and control functions based on the
connections with STM32F103ZGT6 listed in
The Smartcard_CMDVCC and Smartcard_OFF are multiplexed with motor control.
They can be enabled by setting JP15 and JP16 jumpers. Refer to
on page 15

microSD™ card
The 128-Mbyte microSD™ card connected to the SDIO of STM32F103ZGT6 is available on
the board. The microSD™ card detection is managed by standard IO port PF11.
The MicroSDcard_D3 signal is multiplexed with IrDA. It can be enabled by setting the JP22
jumper, as explained in
The MicroSDcard_D0 and microSD™ card CMD are multiplexed with the motor-control
connector. They can be enabled by setting JP17 and JP20 jumpers.
