Product details
Overview
STM32L010F4P6TR from STMicroelectronics is an ultra-low-power 32-bit Arm® Cortex®-M0+ microcontroller in TSSOP20 package, featuring 16 KB Flash, 2 KB SRAM, 128-byte EEPROM, 12-bit ADC (1.14 Msps), and integrated low-power timers including LPTIM and RTC. It operates from 1.8–3.6 V, achieves 0.23 µA Standby current, and supports 5 µs wakeup from Flash-ideal for battery-powered sensor nodes and smart metering endpoints.
For engineers reviewing the STM32L010F4P6TR datasheet, STM32L010F4P6TR pinout, STM32L010F4P6TR application, or STM32L010F4P6TR equivalent, key selection criteria include ultra-low active/standby current, 23 I/Os with 5-V tolerance, integrated bootloader (USART/SPI), SWD debug support, and dual clock domains (HSI16 ±1%, LSE for RTC calibration).
Technical Context
This MCU implements a hierarchical low-power architecture with seven operational modes (Run, Sleep, Low-power Run/Sleep, Stop, Standby), where peripheral clocks and voltage regulators are selectively gated. Its interconnect matrix enables flexible routing of DMA channels to ADC, USART, SPI, I2C, and timers without CPU intervention.
The core integrates a factory-trimmed 16 MHz HSI RC oscillator (±1%), programmable MSI (65 kHz–4.2 MHz), LSE (32.768 kHz) for RTC, and PLL for CPU clock scaling. Reset management includes ultra-low-power BOR with five threshold levels and independent window/independent watchdogs for safety-critical firmware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm Cortex-M0+, 32-bit, up to 32 MHz - delivers 0.95 DMIPS/MHz for deterministic real-time control in resource-constrained systems. |
| Memory | 16 KB Flash + 2 KB SRAM + 128 B EEPROM - supports field firmware updates, data logging with wear leveling, and retention during Stop mode. |
| Power Consumption | 0.23 µA Standby (2 wakeup pins), 0.54 µA Stop+RTC+2 KB RAM - enables >10-year battery life in coin-cell-powered IoT endpoints. |
| ADC | 12-bit, 1.14 Msps, 10-channel, down to 1.8 V - enables high-resolution analog sensing (e.g., temperature, pressure) without external signal conditioning. |
| Clock Sources | HSI16 (±1%), MSI (65 kHz–4.2 MHz), LSE (32.768 kHz), HSE (0–32 MHz) - provides precision timing for RTC, low-jitter communication, and dynamic voltage scaling. |
| I/O Capability | 23 I/Os, 20 of which are 5-V tolerant - simplifies interface with legacy peripherals and mixed-voltage sensor buses without level shifters. |
| Debug & Boot | Serial Wire Debug (SW-DP), pre-programmed USART/SPI bootloader - enables in-system programming and secure firmware recovery without JTAG hardware. |
Pinout & Package
TSSOP20 (6.5 × 4.4 mm, 0.65 mm pitch), ECOPACK2-compliant, surface-mount package optimized for compact PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Main 1.8–3.6 V supply rail; decoupling required per datasheet layout guidelines to ensure stable low-power operation. |
| VSS | Ground reference | Digital ground plane connection; separate analog ground not required due to integrated VREFINT and single-supply ADC design. |
| NRST | Active-low reset input | Asynchronous reset pin with internal pull-up; accepts 5-V tolerant signals and supports external reset supervisor integration. |
| PA0–PA15 | General-purpose I/O | Configurable as GPIO, alternate functions (ADC_IN0–IN9, USART/LPUART TX/RX, SPI/I2C), or wakeup sources in Stop/Standby. |
| PA13/PA14 | SWD debug interface | Serial Wire Debug clock (SWCLK) and data (SWDIO); enables full debugging and flash programming using standard ST-LINK tools. |
| PA15 | SPI1_NSS / TIM2_CH1 | Hardware slave select for SPI master mode or timer capture input - supports synchronous sensor interfacing and precise event timing. |
| BOOT0 | Boot mode selection | High at power-on forces boot from system memory (bootloader); tied low for normal Flash execution - critical for field firmware recovery. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power BOR | Five selectable brownout thresholds (1.65–2.9 V) enable robust operation across wide battery discharge curves without external supervisors. |
| LPTIM ultra-low-power timer | Independent 16-bit timer running from LSE or MSI, consuming <150 nA - ideal for periodic wakeups, pulse counting, or time-stamping in Standby mode. |
| Integrated VREFINT | Internal 1.22 V reference with factory calibration stored in system memory - eliminates need for external reference in ADC measurements and reduces BOM cost. |
| 5-V tolerant I/Os | 23 pins tolerate 5 V on inputs while powered from 1.8–3.6 V - enables direct connection to industrial sensors, RS-232 transceivers, and legacy logic families. |
| Hardware CRC unit | Dedicated 32-bit CRC calculator supporting multiple polynomials - accelerates firmware integrity checks and secure OTA update validation without CPU overhead. |

FAQ
What is the maximum operating frequency and corresponding power supply range?
The STM32L010F4P6TR runs up to 32 MHz when supplied between 2.4 V and 3.6 V (Voltage Range 1). At 1.8–2.4 V (Range 2), max frequency drops to 16 MHz; below 1.8 V, operation is unsupported. These ranges are enforced by the internal voltage regulator and verified in DS12323 Rev 3 Section 6.3.1.
Does this MCU support hardware encryption or secure boot features?
No. The STM32L010F4P6TR does not include hardware cryptographic accelerators (AES, SHA, PKA) or secure boot ROM. Security relies on software-implemented algorithms and external secure elements. For certified secure boot, ST recommends STM32L5 or STM32U5 series MCUs with TrustZone and embedded secure firmware installers.
Can the 128-byte EEPROM be used for storing calibration data across power cycles?
Yes. The 128-byte data EEPROM is independently erasable and writable (10⁵ write/erase cycles, 40-year data retention at 55 °C) and retains contents during all low-power modes including Standby. It is accessed via dedicated HAL drivers and supports byte-level writes without block erasure.
Is the TSSOP20 package RoHS and REACH compliant?
Yes. The STM32L010F4P6TR uses ST's ECOPACK2 packaging standard, fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free matte tin finish and halogen-free molding compound are confirmed in ST's official material declaration (Doc ID 17625).
