STM8L152M8T6 - 16MHz 64KB Low-Power MCU | ST
N.º da peça: STM8L152M8T6 ✓ AtivoSTM8L152M8T6 Visão geral
An ultra-low-power microcontroller is a semiconductor designed to complete control, measurement, and communication tasks while minimizing energy consumption during active operation, standby, and low-power states. The STM8L152M8T6 belongs to the STM8L family, combining a CISC-based STM8 core with embedded Flash and EEPROM in a surface-mount package. This hierarchy places it between general-purpose 8-bit microcontrollers and highly integrated embedded control devices.
Key features include a maximum CPU frequency of 16 MHz, an 8-bit data bus, 64 KB of programmable Flash, and 2 KB of data EEPROM. The integrated RTC supports timekeeping-oriented designs, while LCD support reduces the component count of segmented human-interface panels. The STM8L152M8 series also provides dedicated timer resources, allowing the MCU to measure intervals, generate timing signals, and coordinate periodic system functions without an external timing IC.
The enhanced STM8 CPU core provides increased processing power compared with earlier low-power members of the STM8 family, with operation up to 16 MHz. The device combines 64 KB Flash with a separate 2 KB EEPROM area for persistent data. Its 80-LQFP package provides a large pin count relative to the device footprint, supporting extensive peripheral routing while remaining compatible with standard surface-mount assembly. Operating voltage, RAM capacity, and detailed temperature limits are not stated in the supplied source data and should be confirmed in the manufacturer documentation before design release.
Typical applications include low-power sensor-hub controllers, battery-operated instruments, industrial monitoring nodes, LCD-based user interfaces, real-time-clock systems, and compact embedded products that require more I/O than a small-package MCU can offer. The combination of 64 KB Flash, 16 MHz processing speed, EEPROM, RTC, LCD support, and timers allows a single device to consolidate several peripheral functions.
Designers should confirm the complete pin assignment, supply-voltage limits, decoupling requirements, and low-power configuration strategy against the manufacturer datasheet before PCB release. Because the LQFP footprint contains 80 fine-pitch leads, board assembly should provide suitable land patterns, thermal-via strategy, and soldering profiles. Firmware must also validate the active, standby, and wake-up behavior required by the final power budget.
This page consolidates verified manufacturer and distributor information, source-linked pricing, same-package alternatives, comparison parameters, and practical selection guidance. It is intended to accelerate engineering review while clearly identifying parameter areas that still require datasheet confirmation.

Aplicações típicas
STM8L152M8T6 é adequado para 6 aplicaçãos: Battery-Powered Sensor Hub, LCD Instrument Control Panel, Industrial Monitoring Node, Real-Time Clock Data Logger, Low-Power Metering Device, Battery-Powered Keypad Controller.
Battery-Powered Sensor Hub
STM8L152M8T6 fits a battery-powered sensor hub because its STM8L EnergyLite architecture targets ultra-low-power operation while providing 16 MHz processing and 64 KB of Flash. The MCU can collect readings from compatible sensors, apply local control logic, and store calibration or event data in the 2 KB EEPROM. Its RTC support is useful for timestamped logging without a separate clock IC, while timers can schedule sampling and sensor wake-ups. Before release, verify the numerical active and standby currents and wake-up time in the manufacturer datasheet, because these figures are not present in the supplied source data.
Recomendado
LCD Instrument Control Panel
The integrated LCD support in STM8L152M8T6 makes the device suitable for compact instrument panels where a dedicated display controller would add cost and board area. A 16 MHz STM8 core can manage display updates, button events, and system logic, while 64 KB of Flash provides room for menus and calibration routines. The 2 KB EEPROM can preserve user settings or configuration. The 80-LQFP package also offers more pins than a small MCU for display segments, inputs, and communication functions, although the exact LCD pin mapping must be confirmed from the manufacturer datasheet.
Recomendado
Industrial Monitoring Node
STM8L152M8T6 can serve as the local controller in an industrial monitoring node that combines periodic sensing, status logging, and low-power idle behavior. Its 16 MHz maximum CPU frequency supports responsive control logic, while the integrated timers provide the timing foundation for sampling, watchdog-style supervision, and communication scheduling. The 64 KB Flash capacity accommodates application firmware, and the RTC can preserve event timestamps independently of the external network. The 80-pin LQFP is useful for discrete sensor inputs and industrial interfaces, but supply voltage and environmental ratings must be verified before deployment.
Recomendado
Real-Time Clock Data Logger
The integrated RTC in STM8L152M8T6 supports a compact real-time-clock data logger that must retain accurate timestamps during short power interruptions. The MCU can wake on a timer event, read an external sensor, append a record, and return to a low-power state, while the 2 KB EEPROM provides nonvolatile storage for a small number of configuration values or recent events. At 16 MHz, the core can also handle local filtering or protocol framing. Firmware should define EEPROM endurance, write-cycle handling, and data-retention behavior because those numerical limits are not included in the supplied verified data.
Recomendado
Low-Power Metering Device
STM8L152M8T6 is appropriate for a metering device that combines periodic measurement, local display, and long periods of reduced activity. Its ultra-low-power STM8L positioning, 16 MHz processing capability, and integrated timers allow a design to measure at controlled intervals instead of running continuously. The 64 KB Flash can hold measurement routines and calibration logic, and 2 KB of EEPROM can retain device settings without using Flash wear. The 80-LQFP footprint provides ample external pin access for a sensor interface, LCD, and communications, subject to confirmation of the exact electrical ratings.
Recomendado
Battery-Powered Keypad Controller
The STM8L152M8T6 can implement a battery-powered keypad and status-display controller where fast wake-up, debouncing, and low idle consumption are important. Its 16 MHz core provides ample processing for keypad scanning, menu handling, and status reporting, while timers support periodic scanning or long-press detection. The LCD support can drive a local segmented display without a separate display controller, and EEPROM can store calibration or user preferences. The 80-LQFP package simplifies access to multiple keypad rows and display signals, although actual matrix size and LCD routing must match the verified pin assignment.

Notas de projeto
Calculate the complete power budget from the active current, standby current, RTC state, LCD state, and peripheral wake-up conditions before selecting a battery. Use the manufacturer datasheet for numerical current limits because none are present in the verified snippets. Disable unused peripherals, configure clock and I/O states before sleep, and measure the assembled design with the intended sensor load. A low-power MCU can still consume significant energy if sensors, pull-ups, or communication modules remain active.
Use the exact STMicroelectronics 80-LQFP land pattern and pin-1 orientation rather than a generic LQFP footprint. Place decoupling capacitors close to the device supply pins and route them through the shortest practical path to the ground plane. Keep clock, programming-debug, and sensitive analog routes away from noisy switching nodes. The supplied data does not specify pin-level decoupling assignments, so verify capacitor values, allowed ESR, and placement against the current datasheet before layout sign-off.
Do not substitute an STM8L family member solely because the memory size and package look similar. The supplied cross-reference data identifies candidates, but it does not provide complete pin tables. Compare power pins, ground pins, NRST, oscillator pins, LCD outputs, ADC channels, timer inputs, programming interfaces, and alternate-function mappings. Also verify Flash and EEPROM endurance, operating voltage, and temperature ratings. A true drop-in replacement should preserve both the PCB footprint and the required peripheral connections.
Treat the advertised $3.2526 STM8L152M8T6 price as a market reference rather than a guaranteed five-tier quotation. LCSC showed the component out of stock when the verified result was retrieved, whereas DigiKey stated that orders could ship immediately. For production, obtain a written quotation that specifies quantity breaks, stock, lead time, date code, warranty, and authorized-distributor traceability. The displayed tiers repeat the only verified numeric price because volume-specific prices were not supplied.
Informações de conformidade
The verified Arrow listing states EU RoHS compliant, SVHC Yes, and Automotive No. REACH, lead-free, halogen-free, and conflict-minerals declarations are not present in the supplied data.
