STM32L152-EVAL evaluation board
Introduction
The STM32L152-EVAL evaluation board is a complete demonstration and development
platform for STMicroelectronics' ARM cortex-M3 core-based STM32L152VBT6
microcontroller supporting two I2C, two SPI and three USART channels, 12-bit ADC, 12-bit
DAC, 16 KB internal SRAM and 128 KB Flash, USB FS, LCD controller, touch sensing and
JTAG debugging support.
The full range of hardware features on the board helps you evaluate all peripherals (USB
FS, USART, Audio DAC, microphone ADC, dot-matrix LCD, LCD glass, IrDA, light
TM
dependant resistor (LDR), MicroSD Card
and temperature sensor amongst others) and
develop your own applications. Extension headers make it possible to easily connect a
daughter board or wrapping board for your specific application.
An ST-LINK/V2 is integrated on the board as embedded in-circuit debugger and
programmer for the STM32 MCU.

  • Page 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...
  • Page 17 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.

  • Page 18: Ibias Current Measurement Procedure

    Hardware and layout UM1018 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.
