Smartcard

The STMicroelectronics smartcard interface device ST8024 is used on the STM3210B-
EVAL board for asynchronous 3V and 5V smartcards. It performs all supply protection and
control functions based on the connections with the STM32F10X microcontroller, which are
listed inTable
Table 8.

An example of smartcard is provided with the board called GSM file system sample. With
this board, you can play basic commands, select a file and do simple read/write operations
to become familiar with this interface and the ISO/IEC 7816-3 protocol.

MicroSD card

The 64Mbyte or 128Mbyte MicroSD card, which is connected to SPI1 of the STM32F10x
microcontroller (shared with serial Flash), is available on the board. The MicroSD card chip
selection is managed by the standard IO port PC12.

One I C interface temperature sensor STLM75 (–55°C to +125°C), which is connected to
2
I C1 of the STM32F10x microcontroller, is available on the board. Two discrete N-channel
enhancement MOS-FETs are used to demonstrate how different voltage level devices can
be connected to the same I

Analog input

One BNC connector, CN3, is connected to PC1, the ADC channel 11 of the STM32F10x
microcontroller as an external analog input.
