STM8L152C8T6 - 16MHz 64KB Ultra-Low-Power MCU | STMicroelectronics
料号： STM8L152C8T6 ✓ 量产中STM8L152C8T6 概述
An ultra-low-power microcontroller is an energy-efficient embedded processing device designed to conserve battery energy while still providing real-time control, communications, data acquisition, and user-interface functions. The STM8L152 family belongs to the STM8L low-power MCU hierarchy, combining an 8-bit CPU architecture with integrated analog and communication peripherals for compact, battery-operated equipment.
Key features include 64 KB of Flash for firmware, 4 KB of data RAM, operation up to 16 MHz, and a 1.8 V to 3.6 V supply range. The integrated LCD controller supports compact segmented or matrix displays, while the RTC provides timekeeping for metering, logging, and scheduled control. The ADC, DAC, and comparators reduce the need for external discrete components in sensing and signal-generation systems.
The STM8L152C8T6 combines several embedded peripherals on one device: USART for serial communication, I2C and SPI for bus-connected sensors and memory, timers for periodic and event-driven control, and analog converters for measurements and low-level output control. Its enhanced STM8 CPU core provides increased processing power relative to earlier STM8 devices while retaining an 8-bit architecture suited to control-oriented products.
Typical applications include low-energy sensor nodes, compact industrial data loggers, battery-powered meters, LCD-equipped handheld instruments, smart building controls, and connected monitoring systems. Its 64 KB Flash capacity is useful for moderate protocol stacks, local configuration data, and application firmware, while the LCD and RTC simplify standalone instrument designs.
Designers should preserve the required input-voltage range of 1.8 V to 3.6 V and account for the device's specified low-power operating modes. PCB layout should provide a stable decoupling network near the supply pins and adequate signal-integrity routing for external LCD, communication, and analog interfaces. Firmware selection must also verify that the selected clock and peripheral settings remain compatible with the intended energy budget.
This product page combines verified manufacturer and distributor information with memory, interface, package, application, and replacement guidance. It also distinguishes confirmed drop-in candidates from options that require firmware, package, or feature verification before they can be used as true replacements.

典型应用
STM8L152C8T6 适用于 6 应用s: Battery-Powered Sensor Nodes, Low-Power Data Loggers, LCD-Equipped Handheld Instruments, Smart Building Controls, Industrial Monitoring and Control, Battery-Powered Meters.
Battery-Powered Sensor Nodes
The STM8L152C8T6 fits battery-powered sensor nodes because its ultra-low-power STM8L architecture combines a 16 MHz 8-bit CPU with 64 KB Flash and 4 KB RAM while operating from 1.8 V to 3.6 V. The integrated ADC, comparators, timers, I2C, and SPI allow a node to acquire sensor data, schedule measurements, and communicate through shared buses without several auxiliary devices. The RTC can maintain timestamps when the system sleeps, while the 48-LQFP package keeps the assembly compact. Firmware must select suitable low-power modes and ensure that radio or sensor wake events do not violate timing requirements.
Low-Power Data Loggers
The STM8L152C8T6 is suitable for compact data loggers that store periodic measurements between external transmissions. Its 64 KB Flash provides room for application firmware, configuration handling, and moderate local buffering, while 4 KB RAM supports working state and communication routines. The 16 MHz enhanced STM8 CPU core can service timers, USART, I2C, and SPI interfaces without a higher-power processor. Integrated ADC and comparators simplify front-end coordination, and the RTC provides time references for logging intervals. For long unattended operation, the firmware and external sensor circuitry must be evaluated together against the complete power budget.
LCD-Equipped Handheld Instruments
The STM8L152C8T6 supports LCD-equipped handheld instruments by combining an LCD controller with 64 KB Flash, 4 KB RAM, and a 16 MHz CPU in a 7 mm by 7 mm 48-LQFP package. The LCD controller can reduce the external driver burden for suitable display configurations, while the RTC supports timestamps and timers. USART, I2C, and SPI provide options for external sensors, calibration storage, or host communication. The MCU operates from 1.8 V to 3.6 V, allowing integration into compact battery-operated products. Designers must verify LCD segment or matrix compatibility, available pins, display voltage requirements, and low-power backlight behavior.
Smart Building Controls
The STM8L152C8T6 can serve as the local controller in a smart building node that coordinates sensors, actuators, and communications over a low-power bus. I2C and SPI support shared sensors and memory, USART provides a straightforward host or module interface, and the comparators can implement simple threshold detection with less external circuitry. The 16 MHz CPU and 64 KB Flash are sufficient for protocol handling, configuration, and actuator logic, while the RTC permits scheduled occupancy or environmental-control functions. Because the MCU is not a wireless device, radio selection remains an external design responsibility, and the supply rail must remain within the verified 1.8 V to 3.6 V range.
Industrial Monitoring and Control
The STM8L152C8T6 fits industrial monitoring modules where an 8-bit controller must combine analog measurement with multiple serial interfaces in a compact package. The ADC and comparators support sensor conditioning and threshold supervision, the timers help produce deterministic sampling and control events, and USART, I2C, and SPI cover common field-bus adapter, memory, and sensor connections. Its 64 KB Flash and 4 KB RAM are appropriate for supervisory logic that does not require a Cortex-M-class processor. Operation up to the verified 125 °C maximum specification supports demanding industrial environments, although the complete operating-temperature range and EMC requirements must be confirmed from official documentation.
Battery-Powered Meters
The STM8L152C8T6 is well matched to metering products that require low-power measurement, local display, and periodic communication. The integrated ADC and comparators support analog measurement, the LCD controller can drive a local readout, and the RTC supports time-based tariff, logging, or calibration functions. With 64 KB Flash and 4 KB RAM, the device can host substantial control firmware without external program memory, while I2C and SPI provide paths to metering sensors or nonvolatile storage. Its 1.8 V to 3.6 V operating range supports low-energy designs. Exact metrology accuracy, calibration strategy, and low-power performance must be established with the official electrical specifications.

关键差异点
- Double the Flash memory of the lower-density STM8L152 variant （对比 STM8L152C6T6)

- Broader verified feature set for display and analog control （对比 STM8L151C8T6)
设计说明
Keep the STM8L152C8T6 supply within the verified 1.8 V to 3.6 V operating range and design the system around the device's low-power modes. Place the manufacturer's recommended supply bypass capacitors immediately adjacent to the VDD and VSS pins, with a short return path to the ground plane. Avoid allowing switching-regulator ripple to fall outside the official operating limits. Because the complete electrical characteristics were not supplied, use the official STMicroelectronics datasheet to set voltage tolerances, load-current limits, and power-mode transition conditions.
Use a compact 48-LQFP 7 mm by 7 mm land pattern with exposed thermal and routing considerations handled according to the official package drawing. Provide unobstructed access for inspection and rework, route high-speed or sensitive analog signals away from switching nodes, and maintain a continuous ground reference beneath the device where practical. Pin assignments for LCD, ADC, DAC, comparator, USART, I2C, and SPI functions must be selected together because their alternate-function multiplexing can create conflicts.
Do not treat same-package candidates as automatic drop-in replacements. For STM8L152C6T6, verify that the reduced 32 KB Flash can hold the final firmware and boot code. For STM8L151C8T6, verify the exact pinout, peripheral availability, interrupt mapping, clock behavior, and low-power features. Also confirm any board-level differences in SWD access, supply sequencing, and display or analog functions. These checks prevent mechanical compatibility from being incorrectly interpreted as complete firmware and hardware equivalence.
