2.10 Smartcard
STMicroelectronics smartcard interface chip ST8024 is used on the STM3210E-EVAL board
for asynchronous 3 V and 5 V smartcards. It performs all supply protection and control
functions based on the connections with STM32F103ZGT6 listed in
Table 7
.
The Smartcard_CMDVCC and Smartcard_OFF are multiplexed with motor control.
They can be enabled by setting the jumpers JP15 and JP16. Refer to
Section 2.9: Motor
control on page 10
for details.
2.11 MicroSD
Card
The 128 Mbyte MicroSD Card connected to SDIO of STM32F103ZGT6 is available on the
board. MicroSD Card detection is managed by standard IO port PF11.
The MicroSD Card_D3 is multiplexed with IrDA. It can be enabled by setting the jumper
JP22, as explained in
Section 2.14: IrDA on page 12
.
The MicroSD Card_D0 and MicroSD Card CMD are multiplexed with the motor control
connector. They can be enabled by setting the jumpers JP17 and JP20.

Description
JP15
The CMDVCC is connected to PC6 when JP15 is closed. It should be kept on
open, or the SD Card needs to be removed from the MicroSD Card connector
when PC6 is used by I
2
S or motor control connector. Default setting: not fitted
JP16
The OFF is connected to PC7 when JP16 is closed. It has to be kept on open
when PC7 is used by the motor control connector. Default setting: not fitted

Jumper
Description
JP17
JP17 is used to enable MicroSD Card data line D0. MicroSD Card D0 is enabled
when JP17 is fitted. The JP17 should be kept on open when motor control
connector CN1 is used. Default setting: fitted
JP20
JP20 is used by the motor control connector, refer to
Table 6
for details. JP20
should be kept on open for MicroSD Card operation. JTAG debugging is disabled
when JP20 is fitted.
