Applications

1:Consumer Electronics andamp; Personal Care Devices

Application Examples: Electric toothbrushes, razors, electronic scales, smartwatches/bands (early or basic models), beauty devices, remote controls, toys.

Reason: These devices are typically battery-powered, requiring extremely low standby power to extend battery life. Their functional complexity

can be adequately handled by the 8-bit core and the on-chip 64KB Flash/4KB RAM.

2:Industrial Sensors andamp; Automation

Application Examples: Temperature/humidity/pressure sensors, data loggers, alarms, proximity detectors, handheld instruments (e.g., multimeters, distance meters).

Reason: The built-in 12-bit ADC and DAC can efficiently process analog sensor signals. The ultra-low power feature allows these sensor nodes to operate for long periods in the field or hard-to-power locations. The extended temperature range (-40anddeg;C to +125anddeg;C) ensures reliability in harsh industrial environments.

3:Medical andamp; Health Monitoring

Application Examples: Portable medical devices, blood glucose meters, blood pressure monitors, pulse oximeters, disposable medical sensors.

Reason: Extremely sensitive to power consumption, requiring devices to be ready-to-use or capable of long-term monitoring. The on-chip analog peripherals (ADC, DAC, comparator) can connect directly to biosensors, reducing external components, cost, and enabling miniaturized designs.

4:Smart Metering andamp; Remote Control

Application Examples: Water meters, gas meters, heat meters, smart home sensors (door/window contacts, temperature/humidity sensors), wireless remote control valves.

Reason: This is a classic application scenario for the STM8L series. These devices require battery life spanning years or even decades. The STM8Land#39;s ultra-low power modes (Halt, Active-Halt) are crucial. They are often paired with low-power wireless modules like Sub-1GHz or LoRa to form IoT end nodes.

5:PC Peripherals andamp; Accessories

Application Examples: Wireless keyboard/mouse receivers, USB dongles, game controllers.

Reason: Power-sensitive, need to wake up quickly from sleep, and have strict cost controls.

Description

The high density value line STM8L05xxx devices are members of the STM8L ultra low power 8-bit family.

The value line STM8L05xxx ultra low power family features the enhanced STM8 CPU core providing increased processing power (up to 16 MIPS at 16 MHz) while maintaining the advantages of a CISC architecture with improved code density, a 24-bit linear addressing space and an optimized architecture for low power operations.

The family includes an integrated debug module with a hardware interface (SWIM) which allows non-intrusive In-application debugging and ultra-fast Flash programming.

High density value line STM8L05xxx microcontrollers feature embedded data EEPROM and low-power, low-voltage, single-supply program Flash memory.

All devices offer 12-bit ADC, real-time clock, four 16-bit timers, one 8-bit timer as well as standard communication interface such as two SPIs, I2C, three USARTs and 8x24 or 4x28 segment LCD. The 8x24 or 4x 28-segment LCD is available on the high density value line STM8L05xxx.

The STM8L05xxx family operates from 1.8 V to 3.6 V and is available in the -40 to +85 anddeg;C temperature range.

The modular design of the peripheral set allows the same peripherals to be found in different ST microcontroller families including 32-bit families. This makes any transition to a different family very easy, and simplified even more by the use of a common set of development tools.

All value line STM8L ultra low power products are based on the same architecture with the same memory mapping and a coherent pinout.
