5.5 Thermal recommendation

STLINK-V3PWR is recommended to operate at the temperature range specified in T STLINK-V3PWR uses precision components that are affected by temperature changes. It is recommended to use
it at a place where the thermal gradient or airflow is minimum. A typical laboratory bench or table might be an optimal location.
Accordingly, airflow cooling holes on the top and the bottom of STLINK-V3PWR must be kept free to ease air cooling.
Hence it is recommended to start the measurement after waiting for a few minutes after the product is plugged into the USB port and a connection is established. This ensures the entire product selfheating to reach thermal equilibrium and avoid triggering a selfcalibration sequence during measurement acquisition (refer to
Section 7.2.3 Selfcalibration management).

SMU output (OUT)
The STLINK-V3PWR’s SMU operates as a 1quadrant voltage source and current meter area is illustrated in Figure 8.

7.2.1 Voltage source

The SMU output voltage is programmable from +1.6 to +3.6 V by 100 mV step. The SMU output voltage keeps stable and accurate over the operating measurement area (refer to Figure 8),
even with a large capacitive load (order of 100 µF) that usually causes SMU oscillating. It has excellent load transient response, even for a transient starting from very low current to high current with
fast current rise time (refer to V operating from STANDBY mode (very low current) to RUN mode (high current) without impacting its power supply
voltage. The SMU can source a 500 mA continuous output current. Above 500 mA and up to OCPTH (550 mA) output current, the SMU output starts entering self-protection mode.
Output voltage decreases slowly as output current increases. It can safely tolerate overcurrent and short circuits (refer to Section 7.2.4 Overcurrent and short circuit
management).

The voltage source is OFF after STLINK-V3PWR powers up (USB cable insertion).
The default output voltage is 3.3 V. Any voltage change must be performed before turning on the voltage source.
By default, the voltage source is automatically turned ON when a current measurement acquisition is started.
By default, the voltage source stays ON after a current measurement acquisition ends or stops.

7.2.2 Current measurement

The STLINK-V3PWR SMU is composed of four analog current measurement paths having 50 kHz analog bandwidth. Current sample acquisitions of the four measurement paths are performed by an STM32H745 using two 12bit ADCs working in parallel, each at a 1.6 MHz sampling frequency algorithms aim to manage current range selection and to perform noise reduction. SMU provides a sampling rate of up to 100 kSPS (kilosamples per second) and down to 1 SPS to the host PC via a USB interface.
. The embedded postprocessing

SMU output (OUT)
The four measurement paths have a fixed current range (refer to Figure 9). Range selections are fully automated at run time by postprocessing algorithms allowing a continuous current acquisition from a few nA to 500 mA.

Impact of noise on sampling rate selection
The sampling rate selection has significant impacts on measurements. Using the maximum sampling rate allows the user to catch fast current transient activities but it intrinsically
increases the noise level making small current variations hidden in the noise level. Reciprocally
, using the minimum sampling rate allows the user to measure small current variations and average
the noise but it smooths fast current transient activities.
Note: Sampling rate selection does not impact the current measurement DC accuracy.

7.2.3 Selfcalibration management

STLINK-V3PWR has builtin selfcalibration circuitry to compensate for the current measurements of temperature variation.
A self-calibration is automatically performed during current measurements acquisition every +/- 5°C temperature change inside STLINK-V3PWR.
During the self-calibration sequence, STLINK-V3PWR keeps the SMU output voltage (OUT) enabled but STLINK­V3PWR stops sending measurement data to the host PC. Once the selfcalibration sequence ends, STLINK­V3PWR restarts sending measurement data to the host PC.
A selfcalibration sequence duration is approximately 15 ms and does not require user intervention. Each time a self-calibration occurs:
A popup is displayed on the STM32CubeMonitor-Power windows to inform the user that acquisition data is stopped for self-calibration sequence duration.
The OUT LED turns in orange color (refer to Table 8. OUT LED).

7.2.4 Overcurrent and short circuit management

The SMU output is protected against overcurrent higher than OCPTH (refer to T It can safely tolerate short overcurrent or peak current before triggering an OCP (overcurrent protection). This is
suitable to keep the target application operating without crashing during peak transient activities where current consumption is higher than OCPTH.

Note: Long overcurrent and short circuits are considered fatal errors. Accordingly, the user must disconnect and
reconnect STLINK-V3PWR from the host PC to restart STLINK-V3PWR.
Warning: As mentioned, STLINK-V3PWR tolerates overcurrent and short circuits. Consequently, as
STLINK-V3PWR is supplied from a host PC USB port, the host PC USB port must support the equivalent amount of power consumed during the overcurrent or the short circuit. Else, the host PC USB port OCP might trigger; making STLINK-V3PWR turn OFF. Accordingly,
it is recommended to connect STLINK-V3PWR to a 5 V/3 A USB Type-C® port for a target application running peak activities above STLINK-V3PWR’s operating measurement area.

7.3 Auxiliary power source output (AUX)

The auxiliary power source output is a regulated voltage source programmable from +1.6 to +3.6 V by 100 mV step.
Note:
When STLINK-V3PWR is managed by STM32CubeMonitor-Power, the auxiliary power source output voltage is a mirror of the SMU output voltage.
The auxiliary power source output is generated by a programmable SMPS step-down converter allowing a high powerefficiency conversion from the host PC USB port.
The auxiliary power source can supply a 2000 mA continuous output current with excellent load transient response.
It has a built-in OCP. It can safely tolerate overcurrent and short circuits up to the OCP
Table 13).
Warning: As STLINK-V3PWR is supplied from a host PC USB port, the host PC USB port should be
able to support the equivalent amount of power consumed on the AUX output. Else, the host PC USB port OCP might trigger; making STLINK-V3PWR turn OFF. Accordingly, it is
recommended to connect STLINK-V3PWR to a 5 V/3 A USB Type-C® port.

7.4 Debugger interfaces (SWD/JTAG/VCP)

The STLINK-V3PWR debugger functionalities are detailed in this section. These functionalities are split on the following
Debug: for SWD, JTAG, and SWV protocols
Virtual COM port (VCP): for UART protocol
Bridge: for SPI, I2C, CAN, and GPIOs protocols
Level shifters are integrated with STLINK-V3PWR to adapt debug, bridge, and VCP interface voltage to target application I/Os voltage from 1.6 to 3.6 V.

Debugger interfaces (SWD/JTAG/VCP)

7.4.1 Target voltage connection (T_VCC)

The target voltage (T_VCC) must always be provided from the target application (I/Os voltage reference) to STLINK-V3PWR when the debug interface and bridge functionalities are used.
When connecting the DEBUG connector (using the to pin 3 of the DEBUG connector (refer to Section 9.3 DEBUG (STM32 JTAG/SWD and VCP)). When using the BRIDGE functionalities only, without connecting the DEBUG connector to the target, the target voltage must be
provided through the TVCC pin of the BRIDGE connector (refer to Section 9.4 BRIDGE (I2C, CAN, SPI, UART,
and GPIO)).
Warning: If target voltage is not provided, the VCP interface, debug interface, trigger, and bridge
functionalities do not work.

7.4.4 Virtual COM port (VCP)

The serial interface VCP (UART) is directly available as a Virtual COM port of the PC, connected to the STLINK­V3PWR USB connector exclusively on one or the other connector (UART signals are internally connected).
On the DEBUG connector, the functionality is available without flow control, T_VCP_RX (or RX) signal is the Rx for the target (Tx for STLINK-V3PWR), T_VCP_TX (or TX) signal is the Tx for the target (Rx for STLINK-V3PWR).
On the BRIDGE connector, the functionality is available with or without hardware flow control (CTS/RTS). On the BRIDGE connector TXD signal is the Rx for the target (Tx for STLINK-V3PWR), the RXD signal is the Tx for the target (Rx for STLINK-V3PWR), the CTS signal is the RTS for the target (CTS for STLINK-V3PWR) and the RTS signal is the CTS for the target (RTS for STLINK-V3PWR). The hardware flow control might be activated by physically connecting UART_RTS and/or UART_CTS signals to the target. If not connected, the virtual COM port works without hardware flow control. Note that the hardware flow control activation/deactivation cannot be configured by software from the host side on a Virtual COM port. Consequently configuring a parameter related to that on the host application does not affect the system behavior.
To reach a high UART frequency, it is recommended to use a flat ribbon on the DEBUG connector with all unused signals tied to the ground on the target side.

7.4.5 Baud rate computing

Some interfaces (VCP and SWV) are using the UART protocol. In that case, the baud rate of STLINK-V3PWR must be aligned as much as possible with the target one.
Below is a rule allowing the computation of the baud rates achievable by the 192 MHz/prescaler with prescaler = [24 to 31] then 96 MHz/prescaler with prescaler = [16 to 65535]
Note: The UART protocol does not guarantee data delivery (all the more without hardware flow control). Consequently,
at high frequencies, the baud rate is not the only parameter impacting the data integrity. The line load rate and the capability of the receiver to process all the data also affect communication.

7.5 Bridge functions

STLINK-V3PWR implements a USB interface dedicated to bridging functions from USB to SPI/I2C/CAN/GPIOs of the STM32 microcontroller target. This interface is mainly used by
programming through SPI/I2C/CAN bootloader. An API host software, STLINK-V3-BRIDGE, is provided to extend the use cases and be used for customized needs.
For details regarding performance, refer to Section 8.5 Debug and bridge performance.
