2.1 Development and debug supportVersion 2 of the ST-LINK, called ST-LINK/V2, is embedded on the board. This tool allows on-board program loading and debugging of the STM32L using the JTAG or SWD interface. Third-party debug tools are also supported by the JTAG (CN9) or Trace (CN8) connectors.

To communicate with the embedded ST-LINK/V2, a specific driver needs to be installed on your PC. To download and install this driver, refer to the Software and development tools page for the ultra low power STM32L family available on www.st.com (the install shield is called ST-LINK_V2_USBdriver.exe).

The embedded ST-LINK/V2 connects to the PC via a standard USB cable from connector CN11. The bicolor LED LD5 (COM) advises on the status of the communication as follows:

1. Slow blinking Red, then Off: At power-on before USB initialization.

2. Fast blinking Red, then Off: After the first correct communication between PC and ST-Link/V2 (enumeration).

3. Red On: When initialization between PC and ST-LINK/V2 is successfully finished.

4. Green On: After successful target communication initialization.

5. Blinking Red/Green: During communication with target.

6. Green On: Communication finished and OK.

7. Orange On: Communication failure.

Note: It is possible to power the board via CN11 (embedded ST/LINK/V2 USB connector) even if an external tool is connected to CN8 (trace) or CN9 (external JTAG and SWD).

2.2 Power supplyThe STM32L152-EVAL is designed to be powered by a 5 V DC power supply and to be protected by PolyZen from a wrong power plug-in event. It is possible to configure the evaluation board to use any of the following four power supply sources by setting jumpers JP12, JP13 and JP4 (see Table 1).

● 5 V DC power adapter connected to CN12, the power jack on the board (power supply unit (PSU on silk screen)). The external power supply is not provided with the board but can be ordered separately.

Note: The AC220V to DC5V power adapter PSU-5V2A (recommended, can be ordered from ST order code PSU-5V2A) or equivalent (polarity compatible with CN12) can be used to power the STM32L152-EVAL board via its power jack CN12.

● 5 V DC power with 500 mA limitation from CN11, the USB type B connector of ST-LINK/V2 (USB 5 V power source (ST-LINK/V2 on silkscreen)).

● 5 V DC power with 500 mA limitation from CN1, the USB type B connector (5 V power source (USB on silkscreen)).

● 5 V DC power from CN6, the extension connector for daughterboard (daughterboard power source (Daughter board on JP12 silkscreen).

Various LEDs indicate the power status:

● Red LED LD9 is lit when the STM32L152-EVAL board is powered correctly by 5 V.

● Red LED LD8 is lit when MCU is powered by low voltage (VDD < 1.8 V).

● Yellow LED LD7 is lit when MCU is powered by voltage (1.8 V<VDD<2.2 V).

● Green LED LD6 is lit when MCU is powered by voltage (2.2 V<VDD).

2.16 IDD measurement The built-in IDD measurement circuit implemented allows the consumption measurement of the STM32L152C6T6 while the MCU is in Run or Low power saving modes.

For IDD measurement the circuit below is implemented on STM32L152-EVAL.

Figure 4. STM32L152-EVAL IDD measurement circuit

2.16.1 Run mode

In Run mode, IDD current is measured using the operational amplifier MAX9938FEUK+ (U10) connected to the 1 Ohm shunt resistor (R36).

In this case IDD_CNT_EN remains high during measurement, so R35 remains in short-circuit during the measurement because of transistor T4 which remains ON permanently. Jumper JP4 must be connected between pins 2 and 3.

2.16.2 Low power mode

In Low power modes (Stop or Standby), the operational amplifier MAX9938FEUK+ (U10) is connected to the 1 KOhm shunt resistor (R35), controlled by the analogue switch T4.

In this case the counter 74HC4060 (U6) enabled by IDD_CNT_EN manages the measurement timing according to Figure 5.

Figure 5. STM32L152-EVAL IDD low power modes measurement timing diagram

The principle used to measure a current when the STM32L is in Low power mode is:

1. Configure ADC to measure voltage on the IDD_Measurement pin (PA5).

2. Configure PA0 to serve as wakeup pin.

3. Enter Low power mode after setting IDD_CNT_EN signal low.

4. IDD_WAKEUP rising edge wakes up the MCU after around 300 ms.

5. Start ADC conversion as soon as possible after wakeup in order to measure the voltage corresponding to Low power mode on capacitor C25.

6. Reset the counter by programming IDD_CNT_EN high (in less than 70 ms after the wakeup) to avoid the R35 (1 KOhm) resistor being connected later in Run mode.

In Low power modes, the 1 KOhm resistor is connected when T4 goes off after entering Low power mode. Q12 output of the counter allows connection of the 1 K resistor when the current IDD becomes very low.Figure 5 shows how the counter and T4 ensure that, 150 ms after IDD_CNT_EN falling edge, the shunt resistor R35 is connected between VDD_MCU and the power supply in order to reduce the measurement range to 30 uA full scale when VDD = 1.8 V. Then after another 150 ms for current stabilization, R35 is shorted, the IDD measurement is stored in C25, and the MCU is woken up. After wakeup the MCU can measure the IDD current corresponding to the Low power mode stored in C25.

Note: It is recommended to maintain VDD on the STM32L at a value lower than 3.5 V during low power current measurement to avoid extra current consumption on the NRST pin (U11 pin 14). The reason for this is that the NRST pin of the STM32L is connected to the ST-LINK MCU T_NRST signal (U23 pin 18), and as the ST-LINK is powered at 3.3 V a leakage current is injected into the STM32L NRST pin when MCU VDD becomes equal to or greater than 3.5 V.

2.16.3 Ibias current measurement procedure

In Low power mode the bias current of operational amplifier input (U10 pin 4) is not negligible compared to IDD current (typical Ibias is ~240 nA). To obtain a reliable MCU IDD measurement it is possible to subtract the bias current from the IDD low power measurement since this current is not sinked by the MCU.

The procedure for accurate IDD measurement is:

1. Set jumper on JP4 pins 1 and 2.

2. Follow the Low power mode procedure to measure I1 = I bias.

3. Remove jumper on JP4 pins 1 and 2 and place it on JP4 pins 2 and 3.

4. Follow the low power mode procedure to measure I2 = IDD + I bias.

5. Calculate actual IDD: IDD = I2 - I1.

Note: When jumper JP4 is removed the current consumption of the STM32L can be measured by connecting an ammeter between jumper JP4 pin 1 and pin 2.

Note: RDS (on) typical value of analog switch T4 = 50 micro Ohm, so to improve measurement accuracy it is recommended to take into account the RDS in series with R36 (1 Ohm) in the Idd Run mode current calculation.

Table 12. IDD measurement related jumpers

3.3 Power connector (CN12)Your STM32L152-EVAL evaluation board can be powered from a DC 5 V power supply via the external power supply jack (CN12) shown in Figure 7. The central pin of CN12 must be positive.

Figure 7. Power supply connector CN12 (viewed from front)

3.4 Daughterboard extension connectors (CN6 and CN7)Two 50-pin male headers CN6 and CN7 can connect a daughterboard or standard wrapping board to the STM32L152-EVAL evaluation board. All GPIOs are available on it. The space between these two connectors and position of power, GND and RESET pins are defined as a standard which allows common daughterboards to be developed for several evaluation boards. The standard width between CN6 pin1 and CN7 pin1 is 2700 mils (68.58 mm). This standard is implemented on the majority of evaluation boards.

Each pin on CN6 and CN7 can be used by a daughterboard after disconnecting it from the corresponding function block on the STM32L152-EVAL evaluation board. Please refer to Table 15 and Table 16 for details.
