STM32100B-EVAL

evaluation board

Introduction

The STM32100B-EVAL is an evaluation board for STMicroelectronic’s ARMTM Cortex-M3

core-based STM32F100VBT6 microcontroller. It is designed as a complete development

environment with HDMI CEC, two I2C channels, two SPI channels, three USART channels,

8 KB internal SRAM and 128 KB internal Flash, and JTAG and SWD debugging support.

With a complete range of hardware evaluations features, the STM32100B-EVAL board is

designed to help developers evaluate all device peripherals (such as HDMI CEC, motor

control, LCD, MicroSD Card™, serial Flash, speaker, IrDA and USART) and develop their

own applications. Extension connectors make it possible to easily connect a daughterboard

or wrapping board for a specific application.

An ST-LINK is integrated on the board as an embedded in-circuit debugger and programmer

for the STM32F100VBT6 MCU.

2.1 Power supply

The STM32100B-EVAL board is designed to be powered by a 5 V DC power supply and to

be protected by PolyZen U10 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 CN8, the power supply jack labeled “PSU” (for

power supply unit) on the silkscreen.

●5 V DC power with 500 mA limitation from CN12, the ST-LINK type-B USB connector

labeled “USB” on the silkscreen.

●5 V DC power from both CN4 and CN5, the daughterboard extension connectors

labeled “DTB” (for daughterboard) on the silkscreen.

The power supply is configured by setting jumpers JP9 and JP10 as described in Table 1.

To enable MCU power consumption measurement, JP8 and JP12 should be re-configured

as described in Table 2. (PCB rev B only. See Section 4.5: IDD standby measurement for

details.)

LED LD5 is lit when the STM32100B-EVAL board is correctly powered by 5 V.

Note: The AC220V to DC5V power adapter PSU-5V2A (recommended and can be ordered from

ST, it is not provided with board by default) or equivalent power adapter (polarity compatible

with CN8) can be used to power STM32100B-EVAL board via power jack CN8 on the board.

To order the recommended power supply, use the order code PSU-5C2A.

Table 1. Power jumpers

Jumper Description

JP10

JP10 is used to select one of the three possible power supply resources.

For power supply from the power supply jack (CN8) to the

STM32100B-EVAL only, JP10 is set as shown:

For power supply from the daughterboard connectors (CN4 and CN5)

to the STM32100B-EVAL only, JP10 is set as shown:

For power supply from the ST-LINK USB connector (CN12) to the

STM32100B-EVAL only, JP10 is set as shown (default setting):

For power supply from power supply jack (CN8) to both the

STM32100B-EVAL board and to a daughterboard connected on CN4

and CN5, JP10 is set as shown: The daughterboard must not have its

own power supply connected.

2.2 Boot option

The STM32100B-EVAL board can boot from:

●Embedded user Flash

●System memory with boot loader for ISP

●Embedded SRAM for debugging

The boot option is configured by switches SW1 and SW2 as shown in Table 3.

Note: The hardware implementation of JP4 and the RS-232 interface can be only used when the

Boot0 is at a high level through the onboard switch SW2, which is not the most common

case of usage.

Table 2. MCU power consumption measurement jumpers

Jumper Description

JP8

VDD power is directly connected to MCU VDD when JP8 is set as shown:

(Default setting)

Note: For manual IDD measurement JP8 must be removed and replaced by an ammeter

connected between JP8 pins 1 and 2.

Connect VDD power to MCU with current-sampling resistor, 1Ωor 1KΩ, in series

for IDD current measurement when JP8 is set as shown:

JP12 (Available only on PCB rev B.) Connect IDD_CNT_EN (PE14) to Anti-tamper (PC13) for

IDD current measurement in standby mode when JP12 is closed.

Default setting: Not fitted

2.3 Clock source

Two clock sources are available on the STM32100B-EVAL board for the STM32F100VBT6

microcontroller and RTC.

●X1, 32 KHz crystal for embedded RTC

●X2, 8 MHz crystal with socket for the STM32F100VBT6 microcontroller. It can be

removed from the socket when the internal RC clock is used.

2.4 Reset source

The reset signal of the STM32100B-EVAL board is active low and the reset sources include:

●Reset button B1

●Debugging tools from JTAG connector CN3

●Daughterboard from CN5

●Embedded ST-LINK

●Bootloader_Reset from RS-232 connector CN10

2.5 Audio

The STM32100B-EVAL board supports playback based on a speaker on the board. This

can be disabled or enabled by jumpers JP1 and JP2. The audio volume can be adjusted

using the potentiometer RV1. See Section 4.4: Audio amplifier volume.

2.6 Serial Flash

A 128 Mbit serial Flash connected to SPI1 of the STM32F100VBT6 microcontroller shares

the same SPI port with the MicroSD Card using a different chip select signal. Serial Flash

chip select is managed by the standard I/O port PD9.

2.7 RS-232

Two type D 9-pin connectors, CN10 (USART1) and CN9 (USART2) are available on the

STM32100B-EVAL board.

●CN10 connects to the RS-232 transceiver U15 with Bootloader_Reset and

Bootloader_BOOT0 support.

●CN9 connects to the RS-232 transceiver U13 with RTS/CTS handshake signal support.

2.8 Motor control

The STM32100B-EVAL board supports induction motor control via a 34-pin connector, CN6,

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, heat sink 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 JP7.

Note: On MB871 PCB rev A MC_CurrentA shares PC1 with VBAT_ADCIN through JP3 so the

jumper JP3 must be removed for motor control applications. See Section 4.3: Jumper JP3.

2.9 MicroSD Card

The 1 Gbyte MicroSD Card connected to SPI1 of the STM32F100VBT6 microcontroller

(shared with serial Flash), is available on the board. MicroSD Card chip selection is

managed by the standard I/O port PC12 while the MicroSD card defect signal is managed

by I/O port PE7.

2.10 Temperature sensor

One I2C interface temperature sensor STLM75 (–55°C to +125°C) connected to I2C1 of the

STM32F10x microcontroller, is available on the board.

2.11 Development and debug support

An embedded ST-LINK STM32 JTAG interface developed by STMicroelectronic’s is

available on the STM32100B-EVAL as the default debugger hardware interface.

Of course, third-party debugger interfaces are also supported by the JTAG connector CN3.

Table 6. Motor control jumpers

Jumper Description

JP7

The special motor current sampling operation is enabled when JP7 is fitted (PD2

connected to PB0). The I/O pins PD2 and PB0 are disconnected and can be used by

daughterboard when JP7 is not fitted.

Default setting: Not fitted

JP6 JP6 should be kept open when encoder signal is from pin 31 of motor control connector

CN6. It should be kept closed when analog signal is from pin 31 of CN6 for special motor.

Default setting: Not fitted (open)
