Introduction

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

the high density value line STM8L052R8 microcontroller with a Flash memory density of

64 Kbytes.

For further details on the whole STMicroelectronics high density family please refer to

Section 2.2: Ultra low power continuum.

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).

High density value line devices provide the following benefits:

●

Integrated system

–

64 Kbytes of high density embedded Flash program memory

–

256 bytes of data EEPROM

–

4 Kbytes 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

These features make the value line STM8L05xxx ultra low power microcontroller family

suitable for a wide range of consumer and mass market applications.

Refer to Table 1: High density value line STM8L05xxx low power device features and

peripheral counts and Section 3: Functional overview for an overview of the complete range

of peripherals proposed in this family.

Figure 1 shows the block diagram of the high density value line STM8L05xxx family.
