Doc ID 018780 Rev 4 9/112
1 Introduction
This document describes the features, pinout, mechanical data and ordering information for
the Low density STM8L15xxx devices: STM8L151x2 and STM8L151x3 microcontrollers
with a Flash memory density of up to 8 Kbytes.
For further details on the STMicroelectronics Ultralow power family please refer to
Section 2.2: Ultra-low-power continuum on page 13.
For detailed information on device operation and registers, refer to the reference manual
(RM0031).
For information on to the Flash program memory and data EEPROM, refer to the
programming manual (PM0054).
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, refer to the STM8 CPU programming manual (PM0044).
Low density devices provide the following benefits:
● Integrated system
– Up to 8 Kbytes of low-density embedded Flash program memory
– 256 bytes of data EEPROM
– 1 Kbyte 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
