Key Features
- Ultra-low-power consumption with halt mode current below 400 nA enables multi-year coin-cell battery life in wireless sensor nodes
- Integrated EEPROM eliminates external non-volatile memory cost and board space in data-logging and configuration-storage applications
- 16 MHz STM8 CPU core with 16 KB Flash, hardware ADC, DAC, and DMA in a single LQFP-32 package reduces BOM complexity
- Multiple low-power stop and halt modes with fast wake-up times under 5 µs allow aggressive duty-cycling for energy-constrained designs
Applications
The STM8L152K4T3 is designed for ultra-low-power applications such as wireless sensor nodes, smart meters, wearable health monitors, and remote controls where battery life of several years from a coin cell is required. Its integrated ADC and DAC support analog front-end signal conditioning without external components, making it ideal for environmental sensors measuring temperature, humidity, or gas concentration. The LQFP-32 package and 16 MHz core provide sufficient processing power for simple human-machine interfaces, LCD segment driving, and low-data-rate wireless protocol stacks.

Frequently Asked Questions
How low is the current consumption of STM8L152K4T3 in halt mode, and how does this affect battery life?
In halt mode the STM8L152K4T3 consumes less than 400 nA from a 3 V supply, with the RTC running from a 32.768 kHz watch crystal. For a duty cycle of 1 wake-up per second with 1 ms active time at 16 MHz, the average supply current is approximately 5 µA, allowing a standard 225 mAh CR2032 coin cell to last over 5 years without replacement in a simple sensor-reporting application.
What non-volatile storage does STM8L152K4T3 integrate, and why does it eliminate an external EEPROM?
The STM8L152K4T3 integrates on-chip data EEPROM alongside its 16 KB Flash program memory, providing byte-level writeable non-volatile storage rated for at least 300,000 erase-write cycles at +25°C. This built-in EEPROM removes the need for an external I2C or SPI EEPROM in designs that store calibration coefficients, device configuration, or event logs, saving one component, reducing I2C bus overhead, and eliminating an additional supply bypass capacitor.
For a wearable sensor design, what analog peripherals does STM8L152K4T3 integrate at 3 V supply?
At a 3.3 V supply the STM8L152K4T3 integrates a 12-bit successive-approximation ADC with up to 25 channels, a 12-bit DAC output for analog signal generation, a hardware comparator, and a DMA controller for autonomous ADC-to-memory transfers without CPU intervention. This combination eliminates external ADC and DAC ICs for most wearable applications such as ECG front ends, pulse-oximetry sensors, and temperature compensation circuits in the LQFP-32 package.
When should a designer choose STM8L152K4T3 over an ARM Cortex-M0 part for a battery-powered IoT node?
STM8L152K4T3 is the better choice when the design requires sub-microampere halt current, a simple 8-bit instruction set for smaller code size, and integrated EEPROM—features that many entry-level Cortex-M0 parts lack or offer at higher current. At 16 MHz and 3 V, the STM8L core active current is typically 4 mA versus 6-10 mA for comparable Cortex-M0 devices, resulting in meaningfully longer battery life for duty-cycled IoT sensor nodes transmitting short data packets less than once per minute.
