STM8L152K4T6 - 16MHz 16KB Flash Ultra-Low-Power MCU | STMicroelectronics
料号： STM8L152K4T6 ✓ 量产中STM8L152K4T6 概述
An ultra-low-power microcontroller is a compact embedded controller designed to maintain accurate digital control while minimizing energy use. The STM8L family belongs to the 8-bit microcontroller hierarchy and is intended for battery-powered, portable, industrial, sensing, and control products where low active and standby power can extend operating time between maintenance events. The STM8L152K4T6 combines that low-power positioning with a broad collection of mixed-signal and communications peripherals.
Key features include 16 KB of Flash for firmware, 16 MHz maximum operating frequency, 1 KB of data EEPROM, and dedicated 2.5 V or 3.3 V supply operation. Integrated LCD support is useful in meter, keypad, and panel designs, while the RTC and low-power modes suit timekeeping applications. USART, I2C, and SPI interfaces provide practical options for sensors, transceivers, memory, and external controllers.
The STM8L152K4T6 also integrates a 12-bit-class ADC, DAC, and comparators according to the family-level device description, allowing compact designs to perform analog measurement and control without requiring every conversion function in a separate IC. Its 32-pin LQFP package exposes the mixed-signal and digital resources required for medium-density embedded designs while remaining compatible with conventional leaded PCB assembly methods.
Typical uses include low-energy sensor nodes, LCD utility meters, industrial condition-monitoring terminals, small appliance controllers, battery-powered instruments, and compact data-acquisition systems. The LCD interface, RTC, EEPROM, serial ports, ADC, DAC, and comparators make it especially useful when a single controller must combine display, measurement, timekeeping, and external communication.
Designers should verify the exact pin configuration, operating limits, memory map, and peripheral electrical characteristics in the manufacturer datasheet before layout or production release. Production quantities also require board-level checks for decoupling, analog reference stability, LCD drive requirements, clock configuration, and low-power mode transitions. The verified distributor data supports availability and pricing references, but the available excerpts do not provide a complete timing, power-consumption, or absolute-maximum-rating table.
This product page combines verified manufacturer and distributor information with practical purchasing, comparison, and design guidance. It distinguishes true same-package alternatives from broader functional alternatives and identifies unavailable technical details explicitly instead of estimating them.

典型应用
STM8L152K4T6 适用于 6 应用s: Battery-Powered Sensor Nodes, LCD Utility Meters, Industrial Condition Monitoring, Battery-Powered Instruments, Small Appliance Control, Compact Data-Acquisition Systems.
Battery-Powered Sensor Nodes
The STM8L152K4T6 fits compact battery-powered sensor nodes because it combines a 16 MHz 8-bit core with 1 KB of data EEPROM, low-power-oriented operation at 2.5 V or 3.3 V, and integrated low-power peripherals. Its USART, I2C, and SPI interfaces allow the controller to connect environmental, motion, or industrial sensors without requiring several dedicated interface ICs. The ADC can acquire analog sensor signals locally, while the comparators support threshold-based events with less processing overhead. The 16 KB Flash capacity is suitable for compact protocols and control firmware, although RAM limits must be checked from the official datasheet. For a low-power design, engineers should also review wake-up sources, run-mode timing, peripheral clock requirements, and the exact state of every interface during sleep. The MCU should be paired with high-value leakage control at the board level so that unneeded sensors, pull-ups, and external logic do not dominate standby consumption.
推荐
LCD Utility Meters
The STM8L152K4T6 is well suited to LCD utility meters because its verified feature set includes an LCD interface, real-time clock, 1 KB EEPROM, ADC, and comparators. A metering product can therefore display measurements, retain tariff or calibration values, and implement threshold alarms without a separate display controller. The 16 MHz processor provides control headroom for acquisition and display updates, while the integrated analog blocks reduce board complexity. The 32-pin LQFP 7 x 7 mm package is practical for instrument and panel-oriented designs where a leaded surface-mount package remains acceptable. Engineering validation must include the exact LCD segment and common-drive capability of the selected STM8L152K4 variant, as well as ADC accuracy requirements and EEPROM endurance. The RTC also enables time-stamped metering records, subject to the applicable operating conditions and backup-power arrangement specified in the manufacturer documentation.
推荐
Industrial Condition Monitoring
The STM8L152K4T6 can serve as the local controller in industrial condition-monitoring equipment that must combine analog measurement, serial communications, and low standby demand. Its ADC and comparators support direct sensing of temperature, pressure, vibration, or level signals, while USART, I2C, and SPI provide interfaces to local sensors, memory, or a communications module. The 16 MHz clock and 16 KB Flash are appropriate for compact protocols and supervisory logic, and the 1 KB EEPROM can retain configuration or counters. Because industrial deployments can experience temperature extremes and electrical noise, the design should include proper grounding, filtering, surge protection, and decoupling rather than relying only on the MCU ratings. Firmware should use the watchdog and verified low-power modes where available. A qualification review should confirm the precise operating-temperature grade, analog accuracy, and pin-level behavior in the official STM8L152K4 documentation.
推荐
Battery-Powered Instruments
The STM8L152K4T6 supports battery-powered instruments where a conventional higher-power MCU would add unnecessary energy use. Its ultra-low-power STM8L family positioning, 2.5 V or 3.3 V operating options, RTC, and flexible serial interfaces allow a controller to wake, acquire a reading, communicate the result, and return to a low-energy state. The integrated ADC, DAC, and comparators broaden the design options for excitation, measurement, and threshold detection without requiring separate analog devices. Its 16 KB Flash is suitable for focused instrument firmware, but projects needing extensive calibration tables or complex user interfaces should verify RAM and storage requirements or consider the 32 KB STM8L152K6 family. Hardware design should minimize leakage from pull-up networks and sensors, while firmware should avoid unnecessary polling. Confirm run, standby, and wake-up current from the manufacturer documentation before finalizing the battery-life target.
推荐
Small Appliance Control
The STM8L152K4T6 can control compact appliances where the required interface mix is broader than a simple GPIO-only device. Its timer resources support periodic control functions, the ADC and comparators can evaluate analog feedback or protection signals, and the DAC provides an analog output where the selected variant provides it. USART, I2C, and SPI permit connection to a display, keypad controller, sensor, or external memory. The 32-pin LQFP package provides access to these mixed-signal resources while keeping the assembly compatible with leaded SMD manufacturing. The 16 MHz speed and 16 KB Flash are adequate for compact control logic, provided the application does not exceed the unavailable RAM limit. Designers should review pin multiplexing carefully, because LCD, analog, and serial functions can share package pins. Accurate timing, motor-drive isolation, fault handling, and safe-state behavior must be validated in the system rather than inferred solely from the MCU feature list.
推荐
Compact Data-Acquisition Systems
The STM8L152K4T6 is appropriate for compact data-acquisition systems that need local conversion, control, and communications without a high-power processor. The ADC acquires sensor inputs, the comparators can implement fast threshold events, and the DAC can generate an analog reference or test waveform where required. USART, I2C, and SPI allow the controller to aggregate readings, configure external hardware, or forward results to a host. Its 16 MHz processing capability supports moderate sampling and filtering workloads, while 1 KB of EEPROM can preserve configuration information. Firmware designers must confirm the exact ADC resolution, sampling characteristics, and acquisition timing from the manufacturer datasheet because those figures were not present in the supplied excerpts. Practical implementations should isolate analog inputs, provide local bypass capacitors, maintain a clean reference arrangement, and use shielded or differential signal routing where noise could affect measurements.

设计说明
Design the supply network around the verified 2.5 V or 3.3 V operating options and place the manufacturer-recommended bypass capacitors close to the supply pins. Because the supplied excerpts do not include complete active, standby, and power-down current curves, do not estimate battery life from the operating frequency alone. Review the official datasheet for current by mode, identify which peripherals remain active during sleep, and disable unused board-level loads to preserve the intended low-power advantage.
Separate analog and digital routing and provide a clean, low-impedance ground reference for the ADC, DAC, and comparators. Keep the MCU supply bypass path short, route sensitive analog inputs away from switching nodes and high-current outputs, and use the package pin multiplexing information in the official device documentation before assigning multiplexed LCD, serial, or analog functions. A complete 32-pin pinout was not available in the verified excerpts, so the layout must not be released from distributor summaries alone.
Do not treat STM8L151K4T6 or the STM8L152K6 devices as unconditional drop-in replacements. The K4T3 is the closest documented same-family candidate, but ordering-code behavior must still be checked; the K6 devices double Flash from 16 KB to 32 KB; and the STM8L151 family may differ in peripheral availability. Confirm LCD requirements, peripheral assignment, firmware, memory organization, temperature grade, and package pin compatibility against the official data before approving a substitution.
合规信息
The verified excerpts identify the lifecycle as active but do not explicitly provide RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is not applicable because this is a general-purpose microcontroller rather than an automotive-qualified variant in the supplied data.
