Hardware

4.1.1

STM8L162M8 microcontroller

High-density STM8L162M8 Ultralow power devices feature an enhanced STM8 CPU core

providing increased processing power (up to 16 MIPS at 16 MHz) while maintaining the

advantages of a CISC architecture with improved code density, a 24-bit linear addressing

space and an optimized architecture for low power operations.

All high-density STM8L162M8 microcontroller features include data EEPROM and low

power low-voltage single-supply program Flash memory.

The devices incorporate an extensive range of enhanced I/Os and peripherals, a 12-bit

ADC, two DACs, two comparators, a real-time clock, an AES, 8x40 or 4x44-segment LCD,

four 16-bit timers, one 8-bit timer, as well as standard communication interfaces such as two

SPIs, an I2C interface, and three USARTs. The modular design of the peripheral set allows

the same peripherals to be found in different ST microcontroller families including 32-bit

families.

The STM8L162M8 can be used with the STM8L1528_EVAL board.

STM8L1528_EVAL board (Rev. A) connectors

The STM8L1528-EVAL evaluation board is designed as a complete demonstration and

development platform for the STM8 core based STM8L152M8T6 microcontroller with an I2C

interface, 2 SPI channels, 3 USART channels, a 12-bit ADC, two 12-bit DACs, an LCD

driver, an internal SRAM, data EEPROM and 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 applications.
