STMicroelectronics STM32L010RBT6TR

Overview

STM32L010RBT6TR from STMicroelectronics is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller in LQFP64 package, featuring 128-Kbyte Flash, 20-Kbyte SRAM, 512-byte EEPROM, 12-bit ADC (1.14 Msps), and operation from 1.8 V to 3.6 V. It delivers 0.95 DMIPS/MHz performance and supports sub-100 µA/MHz active power consumption - ideal for battery-powered gas meters, wearable health sensors, and wireless sensor nodes.

For engineers reviewing the STM32L010RBT6TR datasheet, STM32L010RBT6TR pinout, STM32L010RBT6TR application, or STM32L010RBT6TR equivalent, key selection criteria include verified low-power mode current (0.29 µA Standby, 0.86 µA Stop + RTC), 45 5-V-tolerant I/Os, integrated bootloader (USART/I2C/SPI), SWD debug support, and LQFP64 mechanical compatibility with industrial PCB layouts.

Technical Context

The device implements a dual-voltage domain architecture with separate VDD/VDDA rails, enabling precise analog measurement down to 1.8 V while maintaining digital core operation. Its clock system integrates six independent sources: HSE (0–32 MHz), LSE (32.768 kHz), HSI16 (16 MHz ±1%), LSI (37 kHz), MSI (65 kHz–4.2 MHz), and PLL - all configurable via RCC registers for dynamic voltage scaling across Run, Sleep, Stop, and Standby modes.

Power management includes ultra-low-power BOR with five programmable thresholds, POR/PDR, and dedicated regulator control logic that enables seamless transitions between 1.8 V (Range 3) and 3.6 V (Range 1) supply conditions. The 7-channel DMA controller supports concurrent transfers for ADC, USART, SPI, I2C, and timers without CPU intervention - critical for deterministic real-time sensing in energy-constrained systems.

FAQ

What is the maximum operating frequency of the STM32L010RBT6TR?

The STM32L010RBT6TR operates at up to 32 MHz using its internal HSI16 oscillator (±1% accuracy) or external crystal. Frequency scaling is dynamically managed via the RCC and PWR registers to maintain ultra-low power consumption across voltage ranges - with full 32 MHz operation supported at VDD ≥ 2.4 V (Range 1).

Does the STM32L010RBT6TR support hardware encryption or secure boot?

No, the STM32L010RBT6TR does not include hardware cryptographic accelerators (AES, SHA, PKA) or secure boot functionality. It features a 96-bit unique ID for device identification but relies on software-based security implementations. For certified secure applications, ST recommends the STM32L5 series with TrustZone and cryptographic peripherals.

Can the 512-byte EEPROM be used for storing calibration data across power cycles?

Yes, the integrated 512-byte EEPROM supports byte-level read/write operations with 100,000 write/erase cycles and 20-year data retention at 55 °C. It is accessed via dedicated HAL drivers (HAL_FLASHEx_DATAEEPROM_Unlock/Lock) and retains data independently of main Flash - ideal for storing sensor offsets, user preferences, or firmware configuration parameters.

Is the LQFP64 package RoHS and REACH compliant?

Yes, the STM32L010RBT6TR in LQFP64 package is ECOPACK2-compliant, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free matte tin finish, halogen-free molding compound, and fully traceable material declarations are provided in ST's official product change notifications and material declarations.
