IDD measurement and comparator
For IDD measurement the circuit shown in Figure 9 is implemented on the STM8L1526EVAL.
Figure 8.
STM8L1526-EVAL IDD measurement circuit
In Run mode, IDD current is measured using MAX9938FEUK+ (U20) connected to the
2ohm shunt resistor. In this case IDD_CNT_EN remains at a high level during measurement
and the jumper must be connected between pin 1 and pin 2 of JP11.
In Halt mode, the operational amplifier MAX9938FEUK+ (U20) is connected on the 2 Kohm
shunt resistor. To measure a current corresponding to the Halt mode the procedure is:
1.
Configure ADC to measure voltage on IDD_measurement pin.
2.
Configure PE6 as interrupt input on falling edge.
3.
Enter in Halt or active Halt mode with IDD_CNT_EN low.
4.
LP_WAKEUP falling edge wakeup the MCU after 150 ms.
5.
Start ADC conversion as soon as possible after wakeup in order to measure the
voltage corresponding to low power mode on 1 uF capacitor.
6.
Reset the counter by programming IDD_CNT_EN high to avoid 2 Kohm to be
connected later on VDD_MCU.
In Halt mode, the 2 K resistor is connected when T3 goes off after entering Halt mode. Q12
output of the counter allows connection of the 2 K when the current IDD becomes very low.
The measurement timing is given in Figure 9.

The Halt mode measurement procedure can be used in Halt mode and slow or fast active
Halt modes if the IDD current does not exceed 12 uA else the Run measurement procedure
should be used up to 12 mA.
Comparator
Three I/Os are used to implement a comparator feature to be used as low precision ADC in
Figure 10.
●
Comparator noninverting input PD1 connected to the reference capacitor (Cref).

The measurement is performed in three steps:
2.17
1.
Internal reference voltage VREFINT is connected to the comparator inverting input and
Cref to noninverting input to measure the time required to charge the capacitor to
internal reference voltage VREFINT by PE0 used as output through Rref.
2.
The potentiometer is connected to inverting input to measure the time required to
charge Cref to the voltage on potentiometer.
3.
The potentiometer voltage is calculated by software interpolation or using a conversion
table.
IR LED
One IR LED, LD6, is driven by either PA0 through two transistors T1 and T8, or PA0 directly;
depending on the setting of the solder bridge SB7.
Table 12.
IR LED related solder bridges

Description
LD6 is driven by PA0 through two transistors, T1 and T8, when SB7 is set as pad1
connected to pad2 (default setting).
LD6 is driven by PA0 directly when SB7 is set as pad2 connected to pad3.
Note:
20/46
JP6 needs to be set correspondingly for IR LED, please refer to Table 9 for details.

Daughterboard extension connector CN4 and CN10
Two 26-pin male headers CN4 and CN10 can be used to connect the daughterboard or
standard wrapping board to the STM8L1526-EVAL evaluation board. All GPI/Os are
available on it. The space between these two connectors and position of power, GND and
RESET pin are defined as a standard which allows to develop common daughterboards for
several evaluation boards. The standard width between CN4 pin1 and CN10 pin1 is
2700 mils (68.58mm). The standard was implemented on the majority of evaluation boards.
Each pin on CN4 and CN10 can be used by a daughterboard after disconnecting it from the
corresponding function block on the STM8L1526-EVAL evaluation board. Please refer to
Table 14 and Table 15 for details.
