STM8L151C2T6 - 16MHz 8-Bit 4KB MCU | STMicroelectronics
部品番号: STM8L151C2T6 ✓ 生産中STM8L151C2T6 概要
An ultra-low-power microcontroller is a semiconductor controller designed to minimize energy use while monitoring inputs, processing data, and controlling outputs. The STM8L151 belongs to the STM8L family, which combines an 8-bit core, low-power operating modes, analog sensing resources, and serial communication peripherals in a compact embedded-control device. This hierarchy places it between general-purpose processing and dedicated sensing-and-control ICs.
Verified features include operation from 1.8 V to 3.6 V, a 16 MHz maximum clock, 4 KB Flash, 1 KB RAM, a 12-bit ADC, and an industrial temperature range from -40 °C to +85 °C. The low-density memory profile is appropriate for compact products that manage sensors, actuators, user interfaces, or communication nodes without requiring a high-performance application processor.
The enhanced STM8 CPU provides up to 16 MIPS at 16 MHz, balancing processing throughput against the device's low-power positioning. Its integrated analog and digital resources can reduce the number of external components in a design, although the verified web data does not enumerate every peripheral, GPIO count, timer, or communication block. Those details must be confirmed in the manufacturer datasheet before final schematic or firmware decisions.
Typical uses include industrial sensor nodes, compact environmental monitors, low-power control panels, battery-powered measurement equipment, motor-control interfaces, and connected industrial modules. The 48-LQFP package provides enough pin access for mixed analog and digital designs while remaining manageable for automated PCB assembly.
When designing around the STM8L151C2T6, verify the selected operating frequency against the available supply voltage and verify the ADC, timer, and communications requirements against the datasheet. Place decoupling capacitors close to the supply pins and reserve adequate PCB area for thermal dissipation and signal routing.
This page consolidates verified manufacturer and distributor information, package constraints, sourcing details, and honest replacement guidance. It also distinguishes verified drop-in candidates from related devices whose memory or architecture makes them unsuitable as direct substitutes, helping engineers compare alternatives without assuming that a shared package guarantees compatibility.

主な用途
STM8L151C2T6 の用途: 6 件s: Industrial Environmental Sensor Node, Battery-Powered Measurement Instrument, Compact Motor and Actuator Controller, Low-Power Industrial Interface Module, Smart Sensor Front End, Compact Building-Control Endpoint.
Industrial Environmental Sensor Node
The STM8L151C2T6 fits compact environmental sensing because it combines a 12-bit ADC, 16 MHz processing capability, and low-power operation in a 48-LQFP package. The MCU can sample analog sensors, apply calibration and filtering, and report measurements through a serial interface. Its 1.8 V to 3.6 V operating range supports low-voltage sensor systems, while the -40 °C to +85 °C rating suits industrial equipment. The 4 KB Flash limit means firmware should be compact, and the 1 KB RAM requires careful buffer management during acquisition and communications.
おすすめ
Battery-Powered Measurement Instrument
The STM8L151C2T6 is appropriate for battery-powered measurement instruments that spend much of their operating cycle acquiring data rather than performing sustained computation. Its low-power STM8L architecture supports duty-cycled operation, while the 16 MHz core provides up to 16 MIPS when active. The 12-bit ADC supports moderate-resolution measurements, and the 1.8 V to 3.6 V supply range facilitates low-energy rail design. Designers should confirm sleep currents, wake-up timing, and analog accuracy in the manufacturer datasheet because those figures were not included in the supplied search results.
おすすめ
Compact Motor and Actuator Controller
The STM8L151C2T6 can serve as the supervisory controller in a compact actuator system where its 16 MHz 8-bit core handles command decoding, state-machine logic, and fault monitoring. The 48-LQFP package offers more I/O connectivity than a small-outline controller, while 4 KB of Flash is adequate for focused control firmware. The MCU is better suited to supervisory or low-complexity motor-control functions than sophisticated field-oriented control. Exact timer outputs, comparator resources, and pin assignments must be verified before assigning a motor-control topology.
おすすめ
Low-Power Industrial Interface Module
The STM8L151C2T6 is well matched to low-power industrial interface modules that translate sensor inputs or control commands into a serial protocol. Its 1.8 V to 3.6 V range supports compact embedded electronics, while the enhanced STM8 core provides up to 16 MIPS for protocol handling and diagnostic logic. The 48-LQFP footprint is useful when the module requires both analog measurement and multiple digital connections. Because the verified data does not identify the exact UART, SPI, or I2C configuration, firmware and hardware decisions should rely on the manufacturer datasheet rather than assumptions.
おすすめ
Smart Sensor Front End
The STM8L151C2T6 can act as a smart front end for a compact sensor assembly, using its 12-bit ADC to digitize analog inputs and its 8-bit core to apply offset, gain, filtering, and threshold logic. The 4 KB Flash storage favors concise algorithms, while 1 KB of RAM supports limited buffering. A 16 MHz clock provides useful timing headroom for sampling and digital filtering. The MCU should not be assumed to replace a high-resolution analog front end; its converter resolution and accuracy must be checked against the sensor’s noise, dynamic range, and calibration requirements.
おすすめ
Compact Building-Control Endpoint
The STM8L151C2T6 is suitable for compact building-control endpoints that monitor inputs and control simple outputs over a low-power communications link. Its industrial temperature range of -40 °C to +85 °C supports equipment deployed beyond room-temperature environments, and the 48-LQFP package provides a practical pin count for status indicators, sensors, and bus connections. The device’s 4 KB Flash and 1 KB RAM keep it best for endpoint rather than gateway duties. Product-level ESD, surge, isolation, and environmental testing must be added according to the installation requirements.

設計ノート
The verified supply range is 1.8 V to 3.6 V. Before finalizing the power tree, confirm the minimum operating voltage for the selected 16 MHz operating mode and each analog or digital peripheral. Place the MCU supply-decoupling network directly beside the relevant power and ground pins, keep sensitive analog returns separated from switching-current paths, and verify brownout behavior during power transitions. These checks are especially important when the device controls battery-powered equipment where supply voltage can vary over time.
Use the manufacturer pinout and 48-LQFP land pattern rather than inferring connections from the package dimensions. Confirm every multiplexed and alternate-function assignment in the datasheet, especially pins used for ADC inputs, serial communication, and debug functions. Preserve access to programming and debug signals in the production layout, avoid routing fast or switching signals beneath the MCU, and provide a stable ground reference around analog inputs to minimize conversion error.
Do not treat the 4 KB Flash and 1 KB RAM limits as negligible. Include the bootloader, library code, interrupt handlers, configuration tables, and protocol overhead when sizing firmware, and avoid RAM-heavy buffering or recursive routines. Also do not assume that every 48-LQFP microcontroller is a drop-in replacement: shared package dimensions do not guarantee identical pins, voltage ratings, peripheral functions, or firmware-compatible startup behavior.
