What the STM8L052C6 family does
The STM8L052C6 is an 8-bit ultra-low-power microcontroller featuring 32-KB Flash, 256-byte EEPROM, and 2 Kbytes of RAM. It operates on a 1.8 V to 3.6 V supply across a -40 °C to 85 °C temperature range. Key specifications include a maximum clock frequency of 16 MHz, a 12-bit ADC sampling up to 1 Msps, and five distinct low-power modes with consumption as low as 350 nA in Halt. The device supports multiple communication interfaces including SPI, I2C, and USART, along with advanced timers for motor control and quadrature decoding. It integrates an LCD driver for up to 4x28 segments and includes a real-time clock with alarm capabilities. This MCU is designed for applications requiring minimal power consumption, such as battery-operated devices, smart meters, and portable electronics, while maintaining full production status for reliable industrial use.
