The high density value line STM8L05xxx devices are members of the STM8L ultra low power 8-bit family.The value line STM8L05xxx ultra low power family features the 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 ultra-fast Flash programming.High density value line STM8L05xxx microcontrollers feature embedded data EEPROM and low-power, low-voltage, single-supply program Flash memory.All devices offer 12-bit ADC, real-time clock, four 16-bit timers, one 8-bit timer as well as standard communication interface such as two SPIs, I²C, three USARTs and 8×24 or 4×28-segment LCD. The 8×24 or 4x 28-segment LCD is available on the high density value line STM8L05xxx.The STM8L05xxx family operates from 1.8 V to 3.6 V and is available in the -40 to +85 °C temperature range.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.All value line STM8L ultra low power products are based on the same architecture with the same memory mapping and a coherent pinout.
