STM3210B-EVAL
evaluation board
Introduction
The STM3210B-EVAL is an evaluation board for STMicroelectronic’s ARMTM Cortex-M3
core-based STM32F10x 128 K microcontrollers. It is designed as a complete development
environment for the STM32F10x microcontrollers with full speed USB2.0, CAN2.0A/B
compliant interface, two I2C channels, two SPI channels, three USART channels with
smartcard support, internal 20KB SRAM and 128KB Flash, JTAG and SWD debugging.
With a complete range of hardware evaluations features, the STM3210B-EVAL board is
designed to help developers evaluate all device peripherals (such as USB, motor control,
CAN, MicroSD Card™, smartcard, USART) and develop their own applications. Extension
connectors make it possible to easily connect a daughterboard or wrapping board for a
specific application.
This user manual provides information on using the STM3210B-EVAL board and its
hardware features.

The following sections provide jumper settings for configuring your STM3210B-EVAL board
and peripherals.
Two types of jumpers are used on the STM3210B-EVAL board:
●3-pin jumpers with two possible positions, for which the possible settings are presented
in schematics in the following sections
●2-pin jumpers with two possible settings:
– Fitted: the circuit is closed.
– Not fitted: the circuit is open (see Figure 4.).

2.1 LCD configuration
The STM3210B-EVAL can be delivered with either one of two LCDs daughterboards
mounted, depending on the board version.
●MB895/S: only one LCD reference
●MB542: two different LCDs are possible depending on the MB542 version.
These two LCDs look alike and operate in the same way, however they have different control
circuits, and therefore require different software drivers.
You must ensure that the demonstration software pre-loaded in the Flash memory of the
microcontroller on the evaluation board supports the LCD that you have.
2.1.1 MB895/S or MB542 board version B-01 or later
If your STM3210B-EVAL product includes the MB895/S or MB542 board version B-01 or
later, it is mounted with:
●LCD reference AM240320L8TNQW-00H (from Ampire).
●Controller reference is ILI9320 (from ILITEK, www.ilitek.com).
●The products that include this LCD have a label on the daughterboard (to the left of the
display) as shown in Figure 5.
The demonstration software delivered with the evaluation boards that carry this label is
STM3210B-EVAL_DEMO version 1.1 or later. It automatically detects which version of the
LCD is mounted on the daughterboard, and it supports both.

2.1.2 MB542 board version B-00 or earlier
If your STM3210B-EVAL product includes the MB542 board version B-00 or earlier, it is
mounted with:
●LCD reference AM-240320LTNQW01H.
●Controller reference is HX8312-A (from Himax, www.himax.com.tw).
●The products that include this LCD do not have a label on the component side of the
daughterboard as shown in Figure 6. The label is on the solder side, therefore not
visible when the MB452 board is screwed onto the MB525 board.
The demonstration software delivered with the evaluation boards that do not carry a visible
label is STM3210B-EVAL_DEMO version 1.0 or earlier. This software only supports the
LCD reference AM-240320LTNQW01H.
Note: You can download the latest version of the software demonstration from the
STmicroelectronics support site, www.st.com/mcu. The STM3210B-EVAL_DEMO software
is included in the STM3210B-EVAL demonstration software user manual (UM0435)
download file. STM3210B-EVAL_DEMO version 1.1 and later support both types of LCD.

2.2 Power supply
The STM3210B-EVAL board is designed to be powered by a 5 V DC power supply and to be
protected by PolyZen U6 in case of incorrect power supply configuration. It is possible to
configure the evaluation board to use any of the following sources for the power supply.
●5 V DC power adapter connected to CN4, the power supply jack labeled “PSU” (for
Power Supply Unit) on the silkscreen
●5 V DC power with 500 mA limitation from CN1, the type-B USB connector on the
evaluation board labeled “USB” on the silkscreen
●5 V DC power from both CN12 and CN13, the daughterboard extension connectors
labeled “DTB” (for daughterboard) on the silkscreen
The power supply is configured by setting the related jumpers JP4, JP9 and JP11 as
described in Table 2.

2.9 RS-232
Two type D 9-pin connectors, CN6 (USART1) and CN5 (USART2) are available on the
STM3210B-EVAL board. The USART1 connector is connected to the RS-232 transceiver
U10, and the USART2 connector with RTS/CTS handshake signal support is connected to
the RS-232 transceiver U9.
2.10 Motor control
The STM3210B-EVAL board supports induction motor control via a 34-pin connector, CN14,
which provides all required control and feedback signals to and from a motor power-drive
board. Available signals on this connector include emergency stop, motor speed, 3-phase
motor current, bus voltage, heatsink temperature coming from the motor drive board and 6
channels of PWM control signals going to the motor drive circuit.
Special motor current sampling operation is enabled by setting jumper JP8.
2.11 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 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.

selection is managed by the standard I/O port PC12.
2.13 Temperature sensor
One I2C interface temperature sensor STLM75 (–55°C to +125°C), which is connected to
I2C1 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 I2C bus.
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.
2.16 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.
