1 Introduction
This document describes the features, pinout, mechanical data and ordering information of 
the medium density STM8L15x devices (STM8L151Cx/Kx/Gx, STM8L152Cx/Kx 
microcontrollers with a 16-Kbyte or 32-Kbyte Flash memory density). These devices are 
referred to as medium density devices in the STM8L15x and STM8L16x reference manual 
(RM0031) and in the STM8L Flash programming manual (PM0054).
For more details on the whole STMicroelectronics ultra-low-power family please refer to 
Section 2.2: Ultra-low-power continuum on page 12.
For information on the debug module and SWIM (single wire interface module), refer to the
STM8 SWIM communication protocol and debug module user manual (UM0470).For 
information on the STM8 core, please refer to the STM8 CPU programming manual 
(PM0044).
The medium density devices provide the following benefits:
 Integrated system
– Up to 32 Kbytes of medium-density embedded Flash program memory 
– 1 Kbyte of data EEPROM
– Internal high speed and low-power low speed RC
– Embedded reset
 Ultra-low power consumption 
– 195 µA/MHZ + 440 µA (consumption)
– 0.9 µA with LSI 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
All devices offer 12-bit ADC, DAC, two comparators, Real-time clock three 16-bit timers, one 
8-bit timer as well as standard communication interface such as SPI, I2C and USART. A 
4x28-segment LCD is available on the medium-density STM8L152xx line. Table 2: Medium 
density STM8L15x low power device features and peripheral counts and Section 3 on page 
13 give an overview of the complete range of peripherals proposed in this family.
The medium density STM8L15x microcontroller family is 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
Figure 1 on page 13 shows the general block diagram of the device family.
