STM8L052R8T6 STM8 STM8L EnergyLite Microcontroller IC 8-Bit 16MHz 64KB (64K x 8) FLASH 64-LQFP (10x10)
The STM8L052R8T6 is an ultra-low-power 8-bit microcontroller from STMicroelectronics, based on the STM8L core and optimized for energy-efficient embedded applications. This device features up to 64KB of Flash memory, 2KB of RAM, and 1KB of EEPROM, providing ample storage for firmware, data, and configuration parameters. Operating at a maximum frequency of 16MHz, the STM8L052R8T6 integrates a rich set of peripherals, including ADC, DAC, timers, communication interfaces (SPI, I2C, UART), and a 12-bit ADC with up to 16 channels, making it suitable for industrial, medical, and consumer electronics applications where power efficiency is critical.
Designed for ultra-low-power operation, the STM8L052R8T6 supports multiple low-power modes, including Active-Halt, Wait, and Low-Power Run modes, consuming as little as 0.3µA in standby mode and 1.0µA in active-halt mode with RTC. The device is manufactured using ST's 130nm embedded non-volatile memory (NVM) technology, which reduces power consumption while maintaining high reliability. Its wide operating voltage range (1.8V to 3.6V) and temperature range (–40°C to +85°C or –40°C to +125°C for industrial versions) make it ideal for battery-powered and portable devices.
The STM8L052R8T6 integrates advanced power-saving features, such as dynamic voltage scaling, peripheral clock gating, and low-power timer operation, ensuring optimal energy efficiency without compromising performance. It includes up to 38 I/Os with interrupt capability, a 16MHz internal RC oscillator, and a real-time clock (RTC) with calendar function, enhancing its versatility in embedded designs. The microcontroller also supports in-application programming (IAP) and in-circuit debugging (ICD), simplifying development and firmware updates.
This device is widely used in smart meters, wearable devices, home automation, and industrial sensors, where low power consumption, cost-effectiveness, and reliable performance are essential. Its integrated analog peripherals (12-bit ADC, DAC, and temperature sensor) reduce the need for external components, further lowering system costs and power usage. The STM8L052R8T6 is available in a compact 48-pin LQFP package, ensuring easy integration into space-constrained designs.
