STM8L050J3 Description

Short technical summary and product information.

The STMicroelectronics STM8L050J3 is a value-line, 8-bit microcontroller designed for ultra-low-power applications. It features 8 Kbytes of Flash program memory and 256 bytes of data EEPROM, along with 1 Kbyte of RAM. The device supports a wide operating supply voltage range of 1.8 V to 3.6 V and operates within a temperature range of -40 °C to 125 °C.

 

Key features include multiple low-power modes, an advanced STM8 core capable of 16 MHz operation, and various peripherals such as a 12-bit ADC, timers, SPI, I2C, and USART interfaces. The microcontroller also includes a low-power Real-Time Clock (RTC) with calendar functions and digital calibration.

 

This MCU is housed in an SO8N package, making it suitable for space-constrained designs. Its ultra-low-power consumption and robust feature set make it ideal for battery-powered devices and embedded systems requiring efficient performance.
