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 3. MCU power consumption measurement jumpers
Jumper
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
JP8
connected between JP8 pins 1 and 2.
Connect VDD power to MCU with current-sampling resistor, 1
series for IDD current measurement when JP8 is set as shown:
(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.
JP12
Default setting: Not fitted

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
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.
