Introduction

This document describes the features, pinout, mechanical data and ordering information for

the low-density STM8L151x2/3 devices: STM8L151x2 and STM8L151x3 microcontrollers

with a Flash memory density of up to 8 Kbyte.

For further details on the STMicroelectronics ultra-low-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 Kbyte of low-density embedded Flash program memory

–

256 byte of data EEPROM

–

1 Kbyte of RAM

–

Internal high-speed and low-power low speed RC.

–

Embedded reset

•

Ultra-low-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
