STM8L152K6U6 - 16MHz 32KB Ultra-Low-Power MCU | STMicroelectronics
MPN： STM8L152K6U6 ✓ 啟用中STM8L152K6U6 概覽
An ultra-low-power 8-bit microcontroller is a compact embedded-control platform designed to consume little energy while performing sensor reading, timing, communications, data acquisition, and local control functions. The STM8L family hierarchy connects this device to 8-bit microcontrollers, embedded controllers, and semiconductor components suited to battery-operated, industrial, and always-on equipment. Its small package also supports space-constrained designs.
The verified product information identifies 32 KB of Flash, operation up to 16 MHz, and an STM8L152K6-class configuration in a 32-pin UFQFPN package. The product family also provides LCD support, timers, USART, I2C, SPI, ADC, DAC, and comparators according to the supplied datasheet search result. These interfaces make the device suitable for connected sensing, low-power instrumentation, and compact control panels.
The STM8L152K6U6 combines an 8-bit CPU architecture with a broad set of embedded peripherals rather than relying on external interface devices. Timer resources can support periodic measurement and PWM generation, while the ADC and comparators can monitor analog inputs. USART, I2C, and SPI options permit integration with sensors, transceivers, memory, and human-interface modules. The 32 KB Flash capacity provides room for application firmware and configuration data.
Typical uses include low-energy sensor nodes, compact environmental monitors, LCD-driven utility meters, industrial condition-monitoring equipment, and battery-powered accessories. In each case, the device can consolidate several small functions into one controller while keeping the board area limited by the 5 mm by 5 mm package. Designers must still verify operating limits, peripheral availability, and pin multiplexing against the complete manufacturer documentation.
The principal design consideration is package and pin planning. A 32-pin UFQFPN footprint requires careful escape routing, exposed-pad thermal management where applicable, and reflow-profile control. Exact pin names, alternate functions, and electrical limits are not included in the supplied verified excerpts, so they should not be inferred from generic STM8 family diagrams before the complete manufacturer datasheet and package drawing are reviewed.
This page consolidates the verified distributor and manufacturer information, package details, interface capabilities, pricing references, and constrained drop-in alternatives. It also identifies where complete electrical, pinout, lifecycle, and compliance data remain necessary for production qualification rather than presenting unverified values as specifications.

典型應用
STM8L152K6U6 適用於 6 應用s: Battery-Powered Sensor Node, Compact LCD Utility Meter, Industrial Condition Monitoring, Portable Medical Accessory, Smart Home Controller, Low-Power Data Acquisition Module.
Battery-Powered Sensor Node
The STM8L152K6U6 fits battery-powered sensor nodes because its STM8L architecture targets ultra-low-power embedded control and its 16 MHz processing rate supports responsive local measurement and control. The verified peripheral set includes an ADC, comparators, timers, USART, I2C, and SPI, allowing a board to read analog sensors, drive external switches, and communicate with a radio or memory device. Its 32 KB Flash accommodates application firmware, while the 5 mm by 5 mm UFQFPN package preserves space. The primary engineering trade-off is that actual battery life depends on sleep current, wake time, and peripheral activity, which must be measured from the full manufacturer datasheet rather than inferred from the product family description.
推薦
Compact LCD Utility Meter
The STM8L152K6U6 is suitable for compact LCD utility meters because the verified device feature set includes LCD support alongside timers, ADC, DAC, and serial interfaces. An energy meter or flow meter can use the ADC and comparators for signal conditioning, timers for accurate periodic sampling, and USART or I2C for calibration equipment and external sensors. The 32 KB Flash provides room for measurement algorithms and display handling, and the compact 32-pin UFQFPN supports meter enclosure constraints. Because the supplied excerpts do not specify segment count, LCD drive characteristics, or operating voltage, the LCD mapping and bias configuration must be confirmed against the complete datasheet before layout release.
推薦
Industrial Condition Monitoring
The STM8L152K6U6 can serve as the local controller in industrial condition-monitoring equipment that combines vibration, temperature, or level sensing with a low-power communications link. Its 16 MHz clock supports responsive timer and serial-interface handling, while the verified ADC, DAC, and comparator resources support analog measurement and threshold detection. USART, I2C, and SPI provide options for connecting sensors, memory, and industrial transceivers. The 32 KB Flash is useful for local filtering, event logging, and parameter storage. For factory use, engineers should verify transient immunity, supply limits, temperature range, and any required industrial qualification because those details are not present in the supplied excerpts.
推薦
Portable Medical Accessory
The STM8L152K6U6 is appropriate for compact, energy-conscious medical accessories that perform simple sensing, control, and local user-interface functions. Its ultra-low-power 8-bit architecture can manage measurements and timers while its verified USART, I2C, and SPI interfaces connect to sensors or a companion processor. The 32-pin UFQFPN package is useful in handheld products where board volume is constrained, and the 32 KB Flash supports embedded application logic. However, the verified data does not establish medical qualification, electrical safety, leakage current, or operating-temperature limits. Such products therefore require a separate risk assessment and component-qualification review rather than assuming that a general-purpose ultra-low-power MCU is suitable for every medical function.
推薦
Smart Home Controller
The STM8L152K6U6 supports compact smart-home control nodes where low standby power, local sensing, and multiple serial interfaces are valuable. A node can read a sensor through the ADC, control outputs with timers and PWM, and connect to a wireless module through SPI, I2C, or USART. The verified 32 KB Flash capacity is sufficient for moderate embedded applications, while the 5 mm by 5 mm UFQFPN package leaves room for radio and power circuitry. Selection should account for the number and electrical type of I/O pins actually required. If the enclosure is permanently powered, standby current and wake-up behavior may dominate the energy budget; if battery operated, the complete active and sleep current specification must be obtained before selecting the MCU.
推薦
Low-Power Data Acquisition Module
The STM8L152K6U6 can form the core of a compact data-acquisition module because the verified feature set includes an ADC, DAC, comparators, timers, and three common serial interfaces. The 16 MHz clock is suitable for coordinating samples and control traffic, and the 32 KB Flash can hold buffering and configuration routines. I2C or SPI can connect external sensors or nonvolatile storage, while USART can simplify host-controller communication. The DAC permits stimulus generation in suitable low-speed applications, although its exact resolution and output range require confirmation from the full datasheet. The 32-pin package reduces board area, but analog return paths, reference design, and digital isolation must be planned carefully to prevent switching and peripheral activity from degrading measurement accuracy.

主要差異化特點
- Broader verified STM8L152 feature set (對比STM8L151K6U6)
- Twice the Flash memory of the K4 alternatives (對比STM8L152K4U6TR)

設計說明
Treat the 32-pin UFQFPN as a fine-pitch, high-density footprint rather than a generic QFN. Confirm land pattern, terminal length, exposed-pad dimensions, paste mask, and solder mask from the official package drawing before Gerber release. The verified excerpts identify a 5 mm by 5 mm package but do not provide the complete footprint geometry.
Do not select decoupling values or the external component set from family-level assumptions. The supplied data does not contain the STM8L152K6U6 input-voltage range, VDDA requirements, or application-bypass recommendations. Review the complete manufacturer datasheet and use its prescribed capacitor network, including separate treatment of analog supply pins when required.
Place decoupling capacitors immediately at the relevant supply and ground pins and provide a low-impedance ground return. For mixed analog and digital designs, keep ADC and DAC routing away from switching nodes and high-current LED or motor paths. Validate the final return-current arrangement because the supplied excerpts contain no pin names or recommended-layout artwork.
The principal substitution risk is assuming that every 32-pin STM8L device has the same peripheral mapping and memory capacity. STM8L151 and STM8L152 members differ in feature availability, while K4 and K6 densities differ in Flash size. Before replacing STM8L152K6U6, compare the complete pin table, alternate-function matrix, interrupt vector table, firmware image size, and electrical limits.
合規資訊
The supplied verified excerpts do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. These fields remain unknown rather than being inferred.
