STM8L151F3U6TR·UFQFPN-20 MCU

explain

The low-density stm8l151x2 / 3 ultra-low power device has an enhanced stm8cpu core to provide increased processing capacity (16mhz up to 16mips), while maintaining the advantages of CISC architecture, 24 bit linear addressing space and optimized structure for low-power operation.

The series includes an integrated debugging module with hardware interface (swim), which allows non-invasive in application debugging and ultra fast flash programming.

All low-density stm8l151x2 / 3 microcontrollers have embedded data EEPROM and low-power low-voltage single power program flash memory.

The device includes * * * enhanced I / O and peripherals, a 12 bit ADC, two comparators, a real-time clock, two 16 bit timers, an 8-bit timer, and standard communication interfaces such as SPI, an I2C interface and a USART. The modular design of the peripheral set allows the same 32-bit family of peripherals to be included in the st microcontroller family of different st microcontroller families. This makes it easy for any transition to a different family and is made easier by using a common set of development tools.
