Product details
Overview
STM32L010R8T6 from STMicroelectronics is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller in LQFP64 package, featuring 64-Kbyte Flash, 8-Kbyte SRAM, 256-byte EEPROM, 12-bit ADC (1.14 Msps), and integrated RTC with 0.4 µA Stop mode current. It operates from 1.8 V to 3.6 V across –40 to +85 °C and targets battery-powered sensor nodes and smart meters.
For engineers reviewing the STM32L010R8T6 datasheet, STM32L010R8T6 pinout, STM32L010R8T6 application, or STM32L010R8T6 equivalent, key selection criteria include ultra-low-power Stop/Standby modes, 51 fast I/Os (45 5-V tolerant), dual UART support (including LPUART), SPI up to 16 Mbit/s, and hardware CRC unit for firmware integrity verification.
Technical Context
The STM32L010R8T6 integrates a Cortex-M0+ core running at up to 32 MHz with 0.95 DMIPS/MHz performance and dynamic voltage scaling. Its clock system includes factory-trimmed 16 MHz HSI (±1%), 32 kHz LSE for RTC, and PLL for CPU clock multiplication.
Power management features ultra-low-power BOR with five threshold levels, POR/PDR, and multiple low-power modes: Standby (0.27 µA), Stop (0.4 µA), and Stop+RTC+RAM retention (0.8 µA). The device supports serial wire debug (SW-DP) and pre-programmed USART/SPI bootloader.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32L011K4T6 | 32-Kbyte Flash, 2-Kbyte RAM, no EEPROM, LQFP32 package (32-pin) | Lower memory capacity and pin count; suited for simpler sensor endpoints with minimal firmware footprint | Select when cost and board space are constrained and EEPROM or >32 KB Flash is unnecessary |
| STM32L031K6T6 | 32-Kbyte Flash, 8-Kbyte SRAM, 256-byte EEPROM, LQFP32, adds AES-128 accelerator | Same memory layout as L010R8 but in smaller package; lacks LPUART and has fewer I/Os (up to 25) | Choose for security-critical edge devices needing encryption but with lower I/O and communication bandwidth requirements |
Compared with STM32L010R8T6, the L011K4T6 trades memory and peripherals for cost and size reduction, while the L031K6T6 adds cryptographic capability in a compact form factor but sacrifices I/O count and LPUART - making the R8T6 optimal for feature-rich, battery-constrained applications requiring full peripheral flexibility.

FAQ
What is the maximum operating frequency and core architecture of the STM32L010R8T6?
The STM32L010R8T6 uses an Arm Cortex-M0+ core with a maximum CPU frequency of 32 MHz and delivers 0.95 DMIPS/MHz. It supports dynamic voltage scaling to optimize performance versus power consumption across three voltage ranges, enabling efficient operation from 1.8 V to 3.6 V.
Does the STM32L010R8T6 support hardware encryption or secure boot features?
No, the STM32L010R8T6 does not include hardware cryptographic accelerators (e.g., AES, SHA) or secure boot functionality. It provides a 96-bit unique ID for device identification and supports standard flash write protection, but advanced security features require higher-series variants like the STM32L031 or STM32L4xx families.
How many I/O pins are 5-V tolerant, and what is the significance of this specification?
45 of the 51 fast I/O pins on the STM32L010R8T6 are 5-V tolerant. This allows direct interfacing with legacy 5 V logic, sensors, or peripherals without external level shifters - reducing BOM cost and PCB complexity in mixed-voltage industrial or consumer designs.
What development tools and debug interfaces are supported by the STM32L010R8T6?
The STM32L010R8T6 supports Serial Wire Debug (SW-DP) for full-featured debugging and programming via ST-LINK/V2 or compatible probes. It also includes a pre-programmed system memory bootloader accessible via USART or SPI, enabling firmware updates without a debugger in deployed units.
