STM8L1528-EVAL evaluation board
Introduction
The STM8L1528-EVAL evaluation board is designed as a complete demonstration and
development platform for the STM8 core based STM8L152M8T6 microcontroller with I2C,
two SPI channels 3 USART channels, 12-bit ADC, two 12-bit DACs, LCD driver, internal
4 KByte SRAM, 2 Kbyte data EEPROM and 64 KByte Flash program memory as well as
SWIM debugging support.
The full range of hardware features on the board is provided to help you evaluate all the
MCU peripherals (motor control, USART, microphone, audio DAC, LCD, IR LED, IrDA, SPI
Flash, MicroSD card, temperature sensor, EEPROM… etc.) 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 STM8 MCU.

Hardware layout and configuration
The STM8L1528-EVAL evaluation board is designed around the STM8L152M8T6 (80-pin
LQFP package). The hardware block diagram
Figure 2
illustrates the connection between
STM8L152M8T6 and peripherals (LCD glass, dot matrix LCD, serial Flash, EEPROM,
temperature sensor, USART, IrDA, audio, MicroSD card, Motor Control and embedded ST-
LINK/V2) and
