Overview

The STM8L052C6T6 is an 8-bit EnergyLite microcontroller from STMicroelectronics designed for power-sensitive applications. It features a 16MHz STM8 core with 32KB of Flash, a dedicated LCD controller with a step-up converter, and ultra-low-leakage power modes. Operating down to 1.8V, it is optimized for battery-powered devices requiring a balance between performance and minimal current consumption.

Why Choose This Part

This MCU offers a highly efficient power profile with a halt mode current of approximately 0.35uA and the ability to run at 1.8V. The inclusion of a 256-byte EEPROM and a 28-segment LCD controller reduces external component count in user-interface designs. It also features a 3-stage pipeline architecture and DMA to handle data transfers without stalling the core.

Applications

Battery-Powered Handheld Meters
Utilizes the integrated LCD driver and low-power modes to extend battery life in portable instrumentation.
Smart Utility Sensors
Ideal for water or gas meters requiring long-term operation on a single cell with periodic RTC wake-ups.
Wearable Health Monitors
The small footprint and 0.35uA shutdown current suit simple fitness trackers or monitoring patches.
Industrial Remote Terminals
Supports reliable communication via I2C, SPI, and USART for distributed sensor networks.

Getting Started

Developers can begin by using the STM8L0528-DISCOVERY kit or a similar evaluation board. Software development is typically performed using the ST Visual Develop (STVD) or IAR Embedded Workbench for STM8, with debugging handled via the Single Wire Interface Module (SWIM) protocol and an ST-LINK/V2 probe.
