Frequently Asked Questions
What is the maximum clock frequency and core architecture of the STM32L011K4T7?
The STM32L011K4T7 uses an ARM Cortex-M0+ core operating at up to 32 MHz. It integrates 16 KB Flash, 2 KB SRAM, 512 B EEPROM, and a 12-bit ADC, providing a balanced feature set for ultra-low-power embedded control at minimal silicon area.
How does the STM32L011K4T7 achieve long battery life in IoT sensor nodes?
The STM32L011K4T7 is built on STMicroelectronics' ultra-low-power process, achieving stop-mode current below 1 µA with RTC active. Running at 32 MHz from a 1.65 V to 3.6 V supply, the device can operate for years from a coin cell in duty-cycled sensor applications.
What non-volatile storage does the STM32L011K4T7 provide beyond program Flash?
In addition to 16 KB of program Flash, the STM32L011K4T7 integrates 512 bytes of internal EEPROM that supports byte- and word-level writes without erase cycles, enabling reliable storage of calibration data, device parameters, and configuration settings across more than 300,000 write endurance cycles.
When would an engineer choose the STM32L011K4T7 over a larger STM32L0 variant?
An engineer selects the STM32L011K4T7 when the application fits within 16 KB Flash and 2 KB SRAM and requires the smallest possible footprint — the LQFP-32 package with 26 I/O lines and a die optimized for sub-1-µA stop current, making it a lower-cost and smaller-area option than 64 KB or 128 KB STM32L0 variants.
