1 Introduction
This document describes the features, pinout, mechanical data and ordering information of
the medium density value line STM8L052C6 microcontroller with 32-Kbyte Flash memory
density. For further details on the whole STMicroelectronics medium 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).
Medium density value line devices provide the following benefits:
● Integrated system
– 32 Kbytes of medium density embedded Flash program memory
– 256 bytes of data EEPROM
– 2 Kbytes of RAM
– 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
