STM32L010R8T6 - 32MHz Cortex-M0+ 64KB MCU | STMicroelectronics
부품 번호: STM32L010R8T6 ✓ 활성STM32L010R8T6 개요
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and communication interfaces on one device. The STM32L010 belongs to the STM32L0 value line, a low-power branch of the STM32 family of 32-bit embedded processors. Its Cortex-M0+ architecture provides a simple instruction set and deterministic interrupt handling for control, measurement, communications, and low-energy sensor applications.
Low-current operation is a central benefit of the STM32L010R8T6. The manufacturer identifies 0.27 µA in Standby mode with two wakeup pins, 0.4 µA in Stop mode with 16 wakeup lines, and 0.8 µA in Stop mode with the real-time clock and 8 KB of RAM retained. The documented running-current figure reaches 88 µA per MHz, helping designers estimate battery life when active-processing duty cycle is controlled.
The device combines 64 KB of Flash with 8 KB of SRAM and executes code at up to 32 MHz. This combination is appropriate for compact control systems that need more program space than a basic 8-bit controller but do not require a higher-end Cortex-M processor. Its low-power modes allow the processor to remain dormant between external events, reducing unnecessary energy consumption in battery-operated products.
Typical uses include low-power sensor nodes, building-access peripherals, compact industrial controls, portable measurement equipment, and connected products that wake periodically to sample data. The 64-pin LQFP package also provides a practical choice for prototype boards, cost-sensitive production assemblies, and designs requiring a broad selection of exposed GPIO and peripheral connections.
Designers should treat the 1.8 V to 3.6 V range as the operating boundary and confirm every external peripheral voltage before connection. Low-power performance also depends on firmware: disable unused peripherals, select the lowest suitable clock configuration, and use the documented wakeup sources rather than polling continuously. Board-level leakage, pull-up resistors, sensor standby current, and regulator quiescent current can dominate battery life in a complete product.
This page consolidates manufacturer specifications, package details, application guidance, design considerations, and confirmed replacement information for engineers evaluating the STM32L010R8T6. It also distinguishes true footprint-compatible replacements from parts that merely use similar microcontroller features, helping prevent unsuitable substitutions in an existing 64-LQFP design.

일반적인 애플리케이션
STM32L010R8T6 적합 용도: 6 애플리케이션s: Battery-Powered Sensor Node, Building Access Control Peripheral, Compact Industrial Control Module, Portable Measurement Instrument, Remote Environmental Monitor, Connected Appliance Controller.
Battery-Powered Sensor Node
The STM32L010R8T6 fits battery-powered sensor nodes because its 32 MHz Cortex-M0+ core handles sampling, filtering, and control while its 0.27 µA standby and 0.4 µA stop-mode currents limit dormant consumption. A typical design places the MCU in a low-power state between timer or sensor events, wakes through a documented wakeup source, processes the measurement, and returns to sleep. The 1.8 V to 3.6 V supply range also supports compact energy-harvesting and coin-cell power architectures. Battery-life estimates must include the sensor, regulator quiescent current, pull resistors, and radio duty cycle because the MCU alone does not determine total system consumption.
추천
Building Access Control Peripheral
The STM32L010R8T6 is appropriate for compact access-control peripherals that periodically authenticate a credential, update an indicator, or supervise a lock input. Its 64 KB of Flash supports the communication stack and application firmware, while 8 KB of SRAM handles short protocol buffers and control state. The 64-pin LQFP package exposes more pins than a minimal controller package and can simplify implementation of multiple I/O, serial, and status functions. Low-power modes are valuable in battery-backed installations, although the complete design must account for the lock mechanism, credential radio, and wired bus currents.
추천
Compact Industrial Control Module
The STM32L010R8T6 can serve as the control processor in a compact industrial module that reads sensors, evaluates thresholds, and drives discrete outputs. Its Cortex-M0+ architecture and 32 MHz operating speed are sufficient for deterministic control loops, while the -40 °C to 85 °C range supports industrial-temperature designs. The 64-pin LQFP package provides a practical route for bringing out GPIO, communication, and peripheral signals on an assembly-friendly footprint. Designers should still verify system-level EMC, isolation, surge protection, and environmental requirements rather than treating the MCU temperature rating as complete product certification.
추천
Portable Measurement Instrument
The STM32L010R8T6 is well suited to portable measurement instruments that combine sensor acquisition, local display control, and serial data transfer. The 32-bit Cortex-M0+ core supports control logic and communication firmware, and the 64 KB of Flash provides useful program space for calibration and filtering code. Its low-power modes can extend operating time between charging cycles, while the 1.8 V to 3.6 V operating range supports multiple low-voltage power architectures. Front-end accuracy, display current, analog noise, and reference quality remain separate design considerations and should not be inferred from the MCU specifications.
추천
Remote Environmental Monitor
The STM32L010R8T6 supports remote environmental monitoring when measurements are collected periodically and transmitted through a short-range communications interface. The MCU can remain in Stop mode between scheduled samples, using its documented wakeup behavior to reduce energy use, and then process the reading before activating the radio. Its 64 KB of Flash and 8 KB of SRAM are sufficient for lightweight sampling and communication protocols. The system’s effective current should be calculated across the complete operating cycle, including sensor warm-up, radio transmission, voltage-regulator loss, and board leakage.
추천
Connected Appliance Controller
The STM32L010R8T6 can act as the low-cost supervisory controller in a connected appliance, coordinating buttons, indicators, sensors, and a communications link. Its Cortex-M0+ core and 64 KB of Flash are appropriate for small embedded applications, while the 64-pin LQFP package offers access to a broad peripheral set for mixed signal and communication connections. Low-power modes help when the appliance is idle but the control logic must still respond to user input. Product-level safety, EMC, motor-drive protection, and standby-current requirements must be addressed by the complete appliance design rather than by the MCU alone.

설계 노트
Design the power tree around the STM32L010R8T6 operating range of 1.8 V to 3.6 V. Estimated battery-current analysis should include the MCU sleep current, regulator quiescent current, sensor standby current, and external pull resistors rather than using the 0.27 µA standby figure alone. Select the regulator dropout and transient response for the highest load transient, and verify that the complete system remains inside the operating range during wake-up and brownout transitions.
Place decoupling and supporting components close to the device pins, and follow the manufacturer layout guidance in the STM32L010R8 datasheet. Keep sensitive analog and communication routes away from fast-switching nodes and maintain a continuous ground reference beneath signal paths. Because the package is a 64-pin LQFP, use a land pattern and pin-1 orientation verified against the exact ordering code before releasing the PCB artwork.
Do not treat the STM32L010K8T6 as a drop-in substitute for the STM32L010R8T6 because their package options and pin arrangements differ. Also avoid assuming that a microcontroller with a similar CPU frequency has equivalent peripherals, firmware behavior, or current consumption. For a redesign, compare the complete pin table, memory map, peripheral set, clock tree, low-power modes, package dimensions, and application code against the manufacturer documentation.
Although the STM32L010R8T6 is specified from -40 °C to 85 °C, the enclosure, PCB, regulator, and any nearby power component can make the internal temperature higher than ambient. Validate the worst-case operating condition at maximum clock activity and supply voltage. Use the manufacturer thermal information for junction and package-limit calculations, and avoid deriving an unverified thermal resistance or lifetime value.
