STM8L101-EVAL
evaluation board
Introduction
The STM8L101-EVAL is composed of two boards:
■
An STM8L1/L2 motherboard called MB709 which includes all peripherals which are
connected to the MCU on the daughterboard. The motherboard connects to the
daughterboard via two 36-pin connectors.
■
An STM8L1 daughterboard called MB710 which has an STM8L101 MCU.
The motherboard and daughterboard are a complete development platform for
STMicroelectronic's STM8L101 microcontroller with comparator, I2C, SPI, USART and
SWIM debugging support.
The full range of hardware features on the STM8L101-EVAL helps you to evaluate all
peripherals (MicroSD cardTM, USART, EEPROM, LCD, for example) and develop your own
applications.

STM8L1/L2 motherboard
This motherboard is designed to work with an STM8L1 daughterboard.
2.1
Power supply
The motherboard is designed to be powered by a 5 V DC power supply and to be protected
from a wrong power plug-in event by PolyZen Inc. (auto rearmable fuse) U13. It is possible
to configure the evaluation board to provide 5 V power to the daughterboard through the
daughterboard connector.
●
The motherboard is powered by a 5 V DC power adapter connected to CN10, the
power jack on the board (PSU on silk screen for power supply unit).
●
5 V DC power is provided to the daughterboard through an extension connector and
can be set by jumper JP12 (DTB for daughterboard on silk-screen).
●
MCU_VDD can be selected by setting jumper JP11 and is connected to the
daughterboard directly through the daughterboard connector.
The power supply is configured by setting the jumpers JP11 and JP12 as described in
Table 1.
The LED LD6 is lit when the motherboard is powered correctly. JP3 is no longer used.

Reset source
The reset signal of the motherboard is low active. Reset sources include:
●
Reset button B1.
●
Debugging tools from connectors CN5, CN6.
The reset pin PA1 of the STM8L101 is either connected to the reset button B1 or to GND by
the setting of jumper JP1:

Audio
The motherboard supports both audio recording and playback, but audio recording
components (U11 microphone and U12 amplifier) cannot be used with the STM8L101.
The speaker can be disabled or enabled by the setting of jumper JP10.
Audio volume can be adjusted using the potentiometer RV2.

RS-232
One D-type 9-pin RS-232 connector CN8 is available on the motherboard.
RS-232 interface behavior is not guaranteed when the MCU is powered by an adjustable
voltage lower than 3 V.
Note:
To communicate with an RS-232 port on a PC, a 9-pin straight RS-232 cable (direct pin to
pin connection) is needed because:
●
On CN8 the RX signal is connected on pin2 and the TX data on pin 3,
●
On the PC side the RX signal is generally on pin 3 and the TX signal on pin 2.
This standard 9-pin straight RS-232 cable is not provided with the board. Refer to
Section 2.15 for details on RS-232 connector pinout.
2.6
MicroSD card
The 1GByte (or more) MicroSD card connected to the SPI of the STM8L101 through a
voltage level translator U1 (shared with LCD) is available on the board. MicroSD card chip
select is managed by standard I/O port PB4.
2.7
Analog input
The BNC connector footprint present on the board (CN7) cannot be used as it is not
connected to the MCU.
2.8
Development and debug support CN5 and CN6
The two debug connectors are available on the motherboard.

●
CN5, ERNI 4-pin connector (reference 284697 or 214017) for SWIM debugging. It fits

Bi-color LED
A bi-color LED is connected to PB0 through a voltage translator which guarantees that the
bi-color LED works when the STM8L101 is powered by an adjustable voltage from 1.8 V to
3.3 V.
2.11
Economic measurement and potentiometer RV1
The economic measurement solution is demonstrated based on the internal comparator
inside the STM8L101 and potentiometer RV1.
As shown in Figure 5, the voltage divided by resister bridge R10 and R11 can be measured
by using an internal comparator of the STM8L1, with Vref connected to channel 2 of the
comparator and an RC charge circuit connected to the COM channel of the comparator.
To measure the voltage Vin from the potentiometer:
1.
Compare Vref with the voltage on C8 which is charged by a series of pulses generated
by PC4.
2.
Record pulse number PN_Vref when the voltage on C8 reaches voltage reference Vref.
3.
Another charge pulse PN_Vin can be obtained with voltage connected to CH1 also like
PN_Vref.
4.
The voltage Vin can be calculated based on both numbers PN_Vref and PN_Vin.
