STM8L162R8T6 - 16MHz 64KB Ultra-Low-Power MCU | STMicroelectronics
MPN: STM8L162R8T6 ✓ نشطSTM8L162R8T6 نظرة عامة
An ultra-low-power microcontroller is a semiconductor controller designed to minimize energy consumption during active operation and standby periods. The STM8L162 family sits within the broader hierarchy of microcontrollers, embedded processors, and semiconductor control devices. Its 8-bit architecture is suited to compact control tasks that collect sensor information, operate human-interface elements, manage communications, and sequence external hardware without requiring a high-end application processor.
The STM8L162R8T6 combines a 16 MHz maximum clock with 64 KB of program Flash in an LQFP-64 package. The STM8L family designation identifies the device as an EnergyLite low-power MCU family, while the L162x8 group provides a larger pin count and greater peripheral integration than lower-density members. This combination is useful when a design needs more I/O than a small package can provide but does not require a 32-bit processor.
Its 8-bit STM8 CPU core offers up to 16 MIPS at 16 MHz, giving designers deterministic performance for control-loop and firmware workloads. The 64 KB Flash capacity provides room for application code, boot logic, configuration data, and communication routines. Its 64-LQFP package also provides a generous pin count for external sensing, actuators, serial links, and discrete power-control functions, although the exact peripheral assignment must be confirmed against the pin-description table in the manufacturer documentation.
Typical applications include low-power sensor nodes, industrial monitoring equipment, compact control panels, connected accessories, building and automation controllers, and battery-operated embedded products. In these systems, the MCU can manage local inputs, coordinate peripheral functions, and support serial data exchange while conserving energy during inactive intervals. The larger package is particularly useful where field wiring, status indicators, analog channels, or multiple communication interfaces are required.
When designing around the STM8L162R8T6, begin with the manufacturer pin-description table and reference manual because no complete public pin assignment is reproduced on this page. Preserve the supply, ground, reset, and debug connections required by the device, and account for the thermal and electrical requirements of every connected peripheral. Firmware should also be tested across the intended voltage and temperature conditions before deployment.
This product page combines the manufacturer's core device information, package and memory details, sourcing structure, drop-in alternatives, and practical engineering guidance. It is designed to help engineers identify the correct MCU, verify PCB compatibility, compare family alternatives, and plan power-aware embedded designs without requiring repetitive searches across technical documents.

التطبيقات النموذجية
STM8L162R8T6 مناسب لـ 6 التطبيقs: Battery-Powered Sensor Nodes, Industrial Monitoring and Control, Connected Home and Building Devices, Compact HMI and Control Panels, Low-Power Motor and Actuator Control, Portable Measurement and Wearable Devices.
Battery-Powered Sensor Nodes
STM8L162R8T6 fits compact, battery-powered sensor nodes that periodically read external sensors and transmit the results. Its STM8L EnergyLite architecture is intended for low-power operation, while the 8-bit CPU can execute up to 16 MIPS at 16 MHz for control and communication routines. The 64 KB Flash provides room for acquisition logic, filtering, protocol handling, and configuration data. Its 64-pin LQFP also exposes more signal options than a small MCU package. Validate sleep current, active current, analog accuracy, and wake-up timing against the application's duty cycle before deployment.
Industrial Monitoring and Control
The STM8L162R8T6 is suitable for industrial monitoring modules that combine digital inputs, status indicators, local sensing, and serial communications. Its 16 MHz maximum clock provides responsive 8-bit control processing, and 64 KB Flash accommodates application firmware, diagnostics, and protocol stacks. The 64-LQFP package provides a useful pin budget for field-wiring interfaces, actuators, and communication peripherals. For industrial deployment, verify operating voltage, temperature limits, isolation strategy, ESD requirements, and watchdog behavior against the manufacturer documentation.
Connected Home and Building Devices
STM8L162R8T6 can serve as the low-power controller in connected building devices, access controls, environmental controllers, and compact smart-home accessories. The 8-bit STM8 core handles local logic efficiently, while the 64 KB Flash supports control firmware and communication protocols. Its 64-pin LQFP allows several peripherals to share a small board without immediate pin exhaustion. Designers should use the manufacturer GPIO alternate-function table, confirm communication peripheral availability, and evaluate radio standby-current effects before assigning it to mains-powered or battery-powered products.
Compact HMI and Control Panels
The STM8L162R8T6 is appropriate for compact human-interface and control-panel assemblies requiring multiple push buttons, indicators, displays, and local control functions. Its 64-LQFP footprint offers more GPIO and peripheral routing options than low-pin-count packages, and the 16 MHz 8-bit core can manage scanning and state-machine tasks. The 64 KB Flash provides room for interface logic and diagnostics. Confirm LCD or display interface requirements, timer resources, debouncing strategy, and update latency before finalizing the controller architecture.
Low-Power Motor and Actuator Control
STM8L162R8T6 can coordinate stepper-motor, solenoid, valve, or relay-based actuator sequences where the design needs deterministic local control without an application processor. The enhanced STM8 CPU core reaches up to 16 MIPS at 16 MHz, and the 64-pin package provides connections for position inputs, drive controls, and diagnostics. Firmware can implement motion steps, limits, and fault handling locally. Validate timer outputs, minimum pulse widths, supply current, inductive transient protection, and thermal margins with the selected actuator and driver circuitry.
Portable Measurement and Wearable Devices
STM8L162R8T6 suits portable measurement devices and wearable-adjacent controllers that prioritize low energy use and local signal management. The STM8L EnergyLite family provides the low-power foundation, while the 8-bit core processes readings, performs threshold decisions, and updates indicators or a communications link. With 64 KB Flash and a 64-LQFP package, the device provides more firmware and routing capacity than basic low-density MCUs. Confirm analog characteristics, sleep behavior, startup timing, and sensor-interface requirements before committing to the design.

ملاحظات التصميم
Assign the PCB from the manufacturer pin-description table and package drawing rather than from distributor summaries. Route every required power and ground connection, preserve the exposed debug and reset functions, and place decoupling capacitors close to their associated pins. Because the device is a 64-pin LQFP, check routing density between the 0.5 mm leads and maintain adequate assembly clearance around the package perimeter.
Design the power tree around the manufacturer's accepted supply limits, including separate limits that may apply to digital, analog, and peripheral domains. The STM8L162R8T6 is intended for low-power operation, so regulator quiescent current and load-switch leakage can materially affect battery life. Validate active and standby current with the final firmware, clock configuration, sensor load, and external circuitry rather than relying only on nominal core frequency.
Do not treat matching packages as proof of drop-in equivalence. STM8L162R6T6 provides half the Flash of STM8L162R8T6, while STM8L152R8T6 and STM8L151R8T6 belong to different peripheral families. Verify startup code, interrupt vectors, timer channels, communication peripherals, GPIO alternate functions, memory size, and development-tool support before releasing a replacement for production.
Keep switching-capacitor, high-current load, and sensitive analog input routes separated as far as the 64-pin package allows. Use a quiet ground reference for measurement paths, provide local bypass capacitance, and avoid routing fast edges beneath sensitive inputs where practical. If the board supports sensor inputs, communications, and actuator outputs, review return-current paths during schematic capture so these loads do not inject noise through shared supply impedance.
