2.1 STM8L Ultralow power 8-bit family benefits
High density and medium+ density STM8L15xx devices are part of the STM8L Ultralow
power family providing the following benefits:
• Integrated system
– Up to 64 Kbytes of high-density embedded Flash program memory
– Up to 2 Kbytes of data EEPROM
– Up to 4 Kbytes of RAM
– Internal high-speed and low-power low speed RC.
– Embedded reset
• Ultralow power consumption
– 1 µA in Active-halt mode
– Clock gated system and optimized power management
– Capability to execute from RAM for Low power wait mode and Low power run
mode
• Advanced features
– Up to 16 MIPS at 16 MHz CPU clock frequency
– Direct memory access (DMA) for memory-to-memory or peripheral-to-memory
access.
• Short development cycles
– Application scalability across a common family product architecture with
compatible pinout, memory map and modular peripherals.
– Wide choice of development tools
STM8L Ultralow power microcontrollers can operate either from 1.8 to 3.6 V (down to 1.65 V
at power-down) or from 1.65 to 3.6 V. They are available in the -40 to +85 °C and -40 to
+125 °C temperature ranges.
These features make the STM8L Ultralow power microcontroller families suitable for a wide
range of applications:
• Medical and handheld equipment
• Application control and user interface
• PC peripherals, gaming, GPS and sport equipment
• Alarm systems, wired and wireless sensors
• Metering
The devices are offered in four different packages from 48 to 80 pins. Different sets of
peripherals are included depending on the device. Refer to Section 3 for an overview of the
complete range of peripherals proposed in this family.
All STM8L Ultralow power products are based on the same architecture with the same
memory mapping and a coherent pinout.
