8-bit microcontroller with extended functionality STM8L050

Cost-effective and energy-efficient is a typical advantage of 8-bit microcontrollers. STMicroelectronics has expanded the 8-bit uC family of STM8L series with integrated analog functionality, a version of the DMA controller and a separate data EEPROM in the SO-8 package.


The new microcontroller STM8L050 adds ST's functional integration in the low-cost, low-power 8-bit microcontroller field. High Energy Aware Design The newest member of the STM8L family includes a wide range of analog devices with up to six user I/O DMA controllers and separate data EEPROMs in a cost SO-8 package.


Taking into account the STM8 core ST with a frequency up to 16MHz, it offers STM8L050 economical and efficient products with tight supply of resources such as industrial sensors, toys, access cards, electric bicycle controllers, home automation and lighting products, smart printer cartridges And battery charger.


The built-in Direct Memory Access (DMA) controller reduces power consumption by enabling data transfer between peripherals and storage or from storage to storage, making applications faster. A separate EEPROM memory with 256 bytes of capacity allows the application to store important program data even when the microcontroller is powered down. At the same time, flash memory can be used to the maximum extent possible in program code.


In addition to the two comparators STM8L050 four-channel analog-to-digital converter (ADC) with 12 bits and low-power RTC (real-time clock) with programmable alarms and periodic wake-ups, allows designers to make the most of the external analog components. In addition, support for external clocks or internal clocks up to 16 MHz provides greater flexibility in balancing performance and component count.


Other features include 8 KB of on-chip flash, 1 KB of RAM, two 16-bit timers, an 8-bit timer and popular interfaces such as SPI, I2 C and UART.


Based on ST, it offers an ultra-low-power technology STM8L050 low-power mode with current consumption reduced to only 350 nA. In addition, it can operate at voltages between 3.6 V and 1.8V. The microcontroller's operating temperature range is -40 ° C to 125 ° C, which guarantees full specification of the durability and reliability of demanding applications such as industrial control or lighting products.
