STMicroelectronics STM32L010K8T6TR

Overview

STM32L010K8T6TR from STMicroelectronics is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller in LQFP32 package, featuring 64-Kbyte Flash, 8-Kbyte SRAM, 256-byte EEPROM, 12-bit ADC (1.14 Msps), and integrated low-power timers including RTC and ultra-low-power LPTIM. It operates from 1.8 V to 3.6 V across –40 to +85 °C and targets battery-powered sensor nodes and compact IoT endpoints.

For engineers reviewing the STM32L010K8T6TR datasheet, STM32L010K8T6TR pinout, STM32L010K8T6TR application, or STM32L010K8T6TR equivalent, key selection criteria include standby current (0.27 µA), wakeup time (5 µs from Flash), 45 5-V-tolerant I/Os, and dual UART support (USART + LPUART) for energy-aware serial communication.

Technical Context

The device implements a hierarchical low-power architecture with six operational modes (Run, Sleep, Low-power Run, Low-power Sleep, Stop, Standby), where Stop mode retains RTC and 8-Kbyte RAM at 0.8 µA. Its clock system integrates factory-trimmed 16-MHz HSI (±1%), 32-kHz LSE for RTC calibration, and MSI RC (65 kHz–4.2 MHz) for dynamic voltage scaling.

Peripheral interconnect uses a single AHB bus matrix supporting DMA-driven transfers between ADC, SPI, I2C, USART, and timers. The 32-bit Cortex®-M0+ core delivers 0.95 DMIPS/MHz and executes from Flash with zero-wait-state access up to 32 MHz under VDD ≥ 2.4 V.

FAQ

What is the maximum operating frequency of the STM32L010K8T6TR?

The STM32L010K8T6TR operates up to 32 MHz when powered at VDD ≥ 2.4 V, enabled by its 16-MHz factory-trimmed HSI oscillator and PLL. At lower voltages (1.8–2.4 V), maximum frequency drops to 16 MHz per dynamic voltage scaling rules in Section 2.2 of DS12325 Rev 3.

Does the STM32L010K8T6TR support hardware encryption or secure boot?

No. The STM32L010K8T6TR does not include hardware cryptographic accelerators (AES, SHA, PKA) or secure boot circuitry. Security relies on software-implemented algorithms and the 96-bit unique ID for device binding; for certified secure boot, consider STM32L4 or STM32H5 series.

Can the 256-byte EEPROM be used for storing calibration data across power cycles?

Yes. The integrated 256-byte data EEPROM supports byte/word erase and write operations with guaranteed endurance of 100,000 cycles and data retention of 20 years at 85 °C (Section 6.3.9). It is accessed via dedicated PEC (Program/Erase Controller) registers and requires no external components.

Is SWD debugging supported, and what pins are required?

Yes. Serial Wire Debug (SWD) is fully supported using two dedicated pins: SWDIO (PA13) and SWCLK (PA14). No additional pins or configuration are needed; debug access remains functional in all low-power modes except Standby, where the debug domain is powered down.
