.The STM8L001J3M3 is an 8-bit microcontroller with 8 Kbytes Flash, 16 MHz CPU, and integrated EEPROM manufactured by STMicroelectronics. It is part of the MCU Mainstream Value line, optimized for low-cost and code efficiency. With 8 Kbytes of Flash, it can be used for cost sensitive applications, such as consumer electronics, building automation and metering, and portable medical devices. It features an instruction set optimized for code efficiency, with up to 1.25 CoreMark/MHz. It also has an extensive range of peripheral functions and features, such as two 16-bit Timers and two PWM outputs, a UART, I²C, SPI, 12-bit ADC, and 7 channels of 10-bit DAC. With low-power operation down to 0.9 mA/MHz, the STM8L001J3M3 is ideal for battery powered applications.
