STM8L152C4U6 - 16MHz, 16KB Low-Power MCU | STMicroelectronics
Teilenummer: STM8L152C4U6 ✓ AktivSTM8L152C4U6 Übersicht
An ultra-low-power microcontroller is an embedded processing device designed to maintain useful operation while minimizing energy consumption during active and sleep states. The STM8L family sits within the hierarchy of low-power 8-bit microcontrollers, embedded controllers, and general-purpose semiconductors. This positioning makes the STM8L152C4U6 suitable for metering, sensing, access-control, industrial control, consumer accessories, and connected low-power equipment in which battery life, display support, and mixed analog/digital functions matter.
The manufacturer identifies the STM8L152C4U6 as an 8-bit MCU with 16KB Flash, 16MHz operation, and a 48-UFQFPN package. Its documented feature set includes an RTC, 1KB data EEPROM, LCD support, timers, USART, I2C, SPI, ADC, DAC, and comparators. These resources can reduce external component count by consolidating communications, display control, data acquisition, and low-level timing into one device. The 16KB Flash configuration is suitable for compact control firmware that does not require the storage capacity of the larger members in the same family.
The STM8L architecture integrates an 8-bit CPU, memory, and multiple peripheral blocks on a single die. Its communication peripherals support serial links to sensors, transceivers, displays, and other embedded controllers, while the ADC, DAC, and comparators extend the device beyond basic digital logic control. The RTC provides timekeeping for data logging and scheduled operations, and the LCD interface is particularly useful in segmented-display products. Pin-count and exact peripheral availability should be checked against the manufacturer pin description before assigning board functions.
Typical uses include low-energy sensor nodes, compact industrial controllers, portable measurement equipment, LCD-driven utility meters, access terminals, and battery-assisted appliances. In a sensor-node design, the MCU can gather analog measurements, filter them digitally, timestamp them through the RTC, and transmit results through I2C, SPI, or USART. In a display-oriented product, the LCD interface can reduce parallel-display driver requirements while the timers and comparators support background measurement or threshold functions.
PCB planning should reserve the 48-pin UFQFPN land pattern, confirm exposed-pad requirements, and follow the manufacturer recommendations for decoupling and signal routing. Place input and output capacitors close to their associated supply pins, provide a stable clock implementation, and keep analog and communication routes away from noisy switching nodes. Firmware and peripheral allocation should be checked against the target device's 16KB Flash limit before enabling multiple complex functions.
This product page consolidates the manufacturer's core device identification, family positioning, package information, peripheral capabilities, pinout caveat, drop-in family comparisons, and practical PCB guidance into one engineering-focused reference.

Typische Anwendungen
STM8L152C4U6 ist geeignet für 6 Anwendungs: Low-Power Sensor Nodes, LCD Utility Meters, Industrial Control and Condition Monitoring, Battery-Powered Consumer Accessories, Access-Control and Keypad Terminals, Portable Measurement and Test Equipment.
Low-Power Sensor Nodes
The STM8L152C4U6 fits compact sensor nodes because its 16MHz 8-bit core can process measurements while the STM8L architecture supports low-power operating modes. The 12-bit-class application role can use the integrated ADC to acquire analog sensor data, then store parameters or counters in the 1KB data EEPROM. USART, I2C, and SPI provide options for connecting external sensors, radios, or data loggers without requiring a separate communication controller. Its 16KB Flash limit makes disciplined firmware sizing important, but it is adequate for focused acquisition, filtering, threshold detection, and packet-formatting routines. Power the node from the lowest practical system voltage and disable unused peripherals to reduce current consumption.

LCD Utility Meters
The STM8L152C4U6 is suitable for LCD utility meters because STMicroelectronics identifies both LCD support and an RTC in the device. A compact metering product can alternate between sensor acquisition, timekeeping, local display updates, and configuration through USART or I2C. The 16MHz maximum frequency provides useful processing margin for keypad handling, calibration logic, and display formatting, while the 16KB Flash configuration can support a focused firmware image. Validate the required number of LCD segments and the exact display-drive pins in the manufacturer documentation. Low-power operation is especially valuable in battery-powered meters, but the final standby-current target must include the LCD bias network, pull resistors, and any external sensor load.
Empfohlen
Industrial Control and Condition Monitoring
The STM8L152C4U6 can serve as the local controller in industrial condition-monitoring equipment that combines analog sensing, timing, and service communications. Its ADC and comparators support threshold and process-variable measurements, while the RTC can timestamp events or schedule periodic sampling. USART offers a straightforward path to a service connector or higher-level controller, and I2C or SPI can connect sensors and nonvolatile storage. The integrated peripherals allow a smaller controller board than a discrete design, while the 48-pin UFQFPN package supports compact assembly. For factory equipment, confirm the operating-temperature grade, isolation strategy, input protection, and grounding arrangement before installation. Firmware should include watchdogs, communication timeouts, and fault logging within the 16KB memory budget.
Empfohlen
Battery-Powered Consumer Accessories
The STM8L152C4U6 is appropriate for battery-powered accessories where an 8-bit MCU, LCD control, real-time clock, and serial peripherals are more useful than high processing throughput. A compact product can monitor a button or sensor, display status, maintain time, and communicate with a host through USART or I2C. The STM8L ultra-low-power positioning is valuable for extending battery life, while the 48-pin UFQFPN package reduces board area. Use the manufacturer sleep and low-power-mode guidance to define a periodic measurement duty cycle, disable unused clocks and peripherals, and select low-leakage external components. The 16KB Flash limit favors simple control logic and compact libraries, so validate application code and update requirements before committing the layout.
Empfohlen
Access-Control and Keypad Terminals
The STM8L152C4U6 fits access-control and keypad terminals that need local I/O, serial communication, event timing, and low standby consumption. The timers can manage debounce, lockout, and periodic activity, while the RTC supports time-based access schedules and event timestamps. I2C or SPI can connect proximity or credential readers, and USART can link the terminal to a door controller or network interface. The 16KB program space is suitable for a narrowly defined terminal application, particularly when display and communication code remain compact. Confirm the number and electrical type of GPIO pins required by the keypad and reader in the manufacturer pin table. Use watchdogs and validated input protection because physical access-control equipment is exposed to ESD, contact bounce, and long-term connector wear.
Empfohlen
Portable Measurement and Test Equipment
The STM8L152C4U6 is well matched to portable measurement equipment that must combine analog input conditioning, calibration, display support, and host communication within a compact board. The ADC and comparators can process sensor signals, the timers can establish acquisition intervals, and USART or I2C can transfer results and configuration. The RTC allows measured events to be timestamped without adding a separate real-time-clock component. Its 16MHz maximum core frequency and 16KB Flash capacity are appropriate for focused instrumentation firmware, including calibration tables, measurements, and a local menu. Design analog inputs with careful grounding and filtering, keep high-current drive paths separate from comparator and ADC routing, and confirm the device's electrical operating limits before selecting external excitation or protection components.

Wichtigste Unterscheidungsmerkmale
- Balanced 16KB Flash configuration for compact firmware (vs. STM8L152C2U6)
- Lower memory footprint than higher-capacity family members (vs. STM8L152C8U6)
- Direct STM8L152 family continuity with moderate memory expansion (vs. STM8L151C4U6)
Designhinweise
Use the manufacturer's 48-UFQFPN land pattern and verify the exposed-pad connection, pad dimensions, mask openings, and paste stencil before layout release. Keep each supply capacitor close to its corresponding power pin, provide a short return path for every supply connection, and route sensitive analog inputs away from switching-node copper. The target has 48 fine-pitch leads, so inspect the PCB stackup and solder mask with the assembly factory before a high-volume build.
Define the low-power strategy before finalizing peripheral assignments. Disable unused clocks and interfaces, select an appropriate STM8L operating mode, and account for ADC, RTC, LCD, pull-up, and external-sensor current when calculating battery life. Confirm the allowed supply range and absolute maximum limits in the manufacturer datasheet. Avoid driving analog or communication inputs above the verified logic levels, and ensure external pull resistors do not prevent the MCU from entering the intended sleep state.
Do not treat the 16KB Flash figure as the total firmware budget. Include startup code, the bootloader, runtime libraries, interrupt routines, calibration tables, communications protocols, and application code. Likewise, verify that every LCD segment, USART function, I2C address, SPI signal, ADC channel, DAC output, comparator input, and timer instance matches the exact package pinout. Firmware developed for a larger C6 or C8 device may not fit the 16KB C4 configuration even when the PCB footprint is unchanged.
Compliance-Informationen
Compliance status was not established by the manufacturer page or other cited product descriptions. Confirm RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals declarations for the exact ordering code and current regional requirements.
