STM8L051F3 Description

Short technical summary and product information.

The STM8L051F3 is a member of the STM8L ultra-low-power 8-bit microcontroller family from STMicroelectronics. It features an enhanced STM8 CPU core capable of processing up to 16 MIPS at 16 MHz, combined with a CISC architecture for improved code density and optimized low-power operations.

 

Key electrical specifications include an operating supply voltage range of 1.8 V to 3.6 V and a temperature range of -40 °C to 85 °C. The device offers 8 Kbytes of Flash program memory and 256 bytes of data EEPROM, along with 1 Kbyte of RAM. It includes a 12-bit ADC with a sample rate up to 1 Msps and a fast I2C interface operating at 400 kHz.

 

Designed for low-power applications, the STM8L051F3 incorporates five distinct low-power modes, including Halt mode with a current consumption as low as 350 nA and fast wakeup times of 5 μs. It also features an integrated debug module with a SWIM hardware interface for non-intrusive debugging and programming.

 

The microcontroller includes a variety of peripherals such as two 16-bit timers, one 8-bit timer, two watchdog timers, a real-time clock (RTC) with a BCD calendar, SPI, I2C, and USART communication interfaces. Up to 18 I/Os are available, all mappable on interrupt vectors, making it suitable for a wide range of embedded applications.
