MicroSD Card

The 64 Mbyte or 128 Mbyte 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 I/O port PC12.
2.13

Temperature sensor

2
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
2.14

Analog input

One BNC connector, CN3, is connected to PC1, the ADC channel 11 of the STM32F10x
microcontroller as an external analog input.
2.15

IrDA

IrDA communication is supported by the IrDA transceiver U11, which is connected to
USART3 of the STM32F10x microcontroller. It can be enabled or disabled by setting the
jumper JP5.

USB

The STM3210B-EVAL board supports USB2.0 compliant full-speed communication via a
USB type B connector (CN1). The evaluation board can be powered by this USB connection
at 5 V DC with a 500 mA current limitation. USB disconnect simulation can be implemented
by disconnecting a 1.5 K pull-up register from the USB+ line. The USB disconnect
simulation feature is enabled by setting JP1.

IrDA jumpers
Enables/disables the IrDA transceiver. IrDA is enabled when JP5 is fitted, and
disabled when JP5 is not fitted.
Default setting: Fitted
USB jumpers
USB 1.5 K pull-up register is always connected to USB+ line when
JP1 is set as shown.
USB 1.5 K pull-up register can be disconnected by software from the
USB+ line when JP1 is set as shown (default setting). In this case,
USB connect/disconnect features are managed by the standard IO
port PD9.
