STMicroelectronics has introduced the STM8L050, a new 8-bit microcontroller designed to increase feature integration in low-cost, low-power applications. As part of the ultra-energy-efficient STM8L series, the STM8L050 comes in a low-cost SO-8 package and integrates extensive analog peripherals, a DMA controller, and independent data EEPROM across its six user I/O pins.
Built on the energy-efficient 16 MHz STM8 processor core, the STM8L050 delivers a balance of performance and cost-effectiveness for resource-constrained applications. Target uses include industrial sensors, toys, access cards, e-bike controllers, home automation systems, lighting products, smart printer cartridges, and chargers.
The integrated Direct Memory Access (DMA) controller simplifies data transfers between peripherals and memory, or from memory to memory, which enhances processing performance and reduces power consumption. Additionally, 256 bytes of independent EEPROM allow for critical data storage when the MCU is powered off, maximizing the available flash memory for application code.
In addition to two comparators, the STM8L050 features a 4-channel, 12-bit ADC and a low-power RTC with programmable alarm and periodic wakeup capabilities, enabling designers to reduce external analog component count. The device supports both internal and external clock sources up to 16 MHz, offering flexibility in balancing performance against Bill of Materials (BOM) cost.
Other features include 8 KB of flash memory, 1 KB of RAM, two 16-bit timers, one 8-bit timer, and standard communication and debug interfaces such as SPI, I2C, UART, and SWIM.
As an STM8L microcontroller featuring ST's ultra-low-power technology, the STM8L050 has a power-saving mode that consumes just 350 nA and operates on a wide voltage range of 1.8V to 3.6V. The device is rated for a temperature range of -40°C to 125°C, ensuring reliable operation in demanding applications such as industrial controls and lighting systems.
