STMicroelectronics STM32L010C6T6TR

Overview

STM32L010C6T6TR from STMicroelectronics is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller in LQFP48 package, featuring 32-Kbyte Flash, 8-Kbyte SRAM, 256-byte EEPROM, 12-bit ADC (1.14 Msps), and integrated RTC with 0.6 µA Stop mode + RTC + RAM retention. It targets battery-powered metering and sensor nodes requiring long runtime and robust analog acquisition.

For engineers reviewing the STM32L010C6T6TR datasheet, STM32L010C6T6TR pinout, STM32L010C6T6TR application, or STM32L010C6T6TR equivalent, key selection criteria include ultra-low-power mode current (0.23 µA Standby), 31 I/Os with 5-V tolerance, 76 µA/MHz active efficiency, and LPUART/low-power timer support for intermittent sensing and wake-on-event operation.

Technical Context

The STM32L010C6T6TR implements a dual-voltage domain architecture with separate VDD/VDDA supplies, enabling precise analog measurement down to 1.8 V while maintaining digital operation. Its clock system integrates factory-trimmed 16 MHz HSI (±1%), 32 kHz LSE for RTC calibration, and multispeed MSI (65 kHz–4.2 MHz) for dynamic power scaling.

Low-power operation is enforced via five hierarchical modes: Run, Sleep, Low-power Run, Stop, and Standby - each disabling specific peripherals and clocks. The 5 µs wakeup from Flash and hardware-accelerated CRC unit support rapid event response and secure firmware integrity verification in constrained-edge devices.

FAQ

What is the maximum operating frequency and core type of the STM32L010C6T6TR?

The STM32L010C6T6TR features an Arm Cortex-M0+ core with a maximum CPU frequency of 32 MHz. It delivers 0.95 DMIPS/MHz, supporting deterministic real-time execution. The core operates across a 32 kHz to 32 MHz range, enabled by internal oscillators (HSI16, MSI) and external clock sources, with dynamic voltage scaling to optimize power versus performance.

Does the STM32L010C6T6TR support 5-V tolerant I/Os, and how many are available?

Yes, the STM32L010C6T6TR provides 31 5-V tolerant I/Os out of its total 38 GPIOs. These pins tolerate up to 5.5 V regardless of VDD level, allowing direct interfacing with legacy 5-V sensors, displays, and logic without external level-shifting circuitry - a key advantage in mixed-voltage industrial and metering systems.

What are the lowest power consumption modes and their typical current draw?

The lowest power modes are Standby (0.23 µA with 2 wakeup pins) and Stop mode with RTC + 8-Kbyte RAM retention (0.6 µA). Both retain critical state and support fast wake-up: Standby achieves 5 µs wakeup from Flash, while Stop mode maintains real-time clock accuracy and low-jitter timing for periodic sensor sampling in battery-constrained deployments.

Is there built-in EEPROM, and what is its endurance and retention specification?

Yes, the STM32L010C6T6TR integrates 256 bytes of true EEPROM with 100,000 write/erase cycles endurance and 20-year data retention at 55 °C (per DS12324 Rev 3, Table 42). This eliminates need for external nonvolatile memory in applications requiring frequent parameter updates, such as calibration data storage or usage counters in metering devices.
