2 Description
The Low density STM8L15xxx Ultralow power devices feature an enhanced STM8 CPU
core providing increased processing power (up to 16 MIPS at 16 MHz) while maintaining the
advantages of a CISC architecture with improved code density, a 24-bit linear addressing
space and an optimized architecture for low power operations.
The family includes an integrated debug module with a hardware interface (SWIM) which
allows non-intrusive in-application debugging and ultrafast Flash programming.
All Low density STM8L15xxx microcontrollers feature embedded data EEPROM and low
power low-voltage single-supply program Flash memory.
The devices incorporate an extensive range of enhanced I/Os and peripherals, a 12-bit
ADC, two comparators, a real-time clock, two 16-bit timers, one 8-bit timer, as well as
standard communication interfaces such as an SPI, an I
2
C interface, and one USART. The
modular design of the peripheral set allows the same peripherals to be found in different ST
microcontroller families including 32-bit families. This makes any transition to a different
family very easy, and simplified even more by the use of a common set of development
tools.
