STM8L151K6T6 - 16MHz 32KB 8-Bit MCU | STMicroelectronics
部品番号: STM8L151K6T6 ✓ 生産中STM8L151K6T6 概要
An 8-bit microcontroller is a microprocessor core integrated with Flash memory, RAM, timers, serial interfaces, GPIO and other peripherals on one semiconductor package. The STM8L family sits within the broader embedded-controller hierarchy: MCU → microcontroller → embedded processing IC → semiconductor. Its low-power positioning makes it useful where the system must continue monitoring or controlling sensors while limiting energy consumption between active operations.
The verified feature set includes 16 MHz maximum clock speed, 32 KB of Flash organized as 32K x 8, 2 KB RAM, an 8-bit instruction set and a 32-pin LQFP package. One indexed source lists 41 I/O ports, although the exact pin names and exposed functions were not included in the supplied data. The LQFP-32 package provides a conventional surface-mount footprint with accessible leads, making the MCU suitable for compact control boards assembled with standard pick-and-place and reflow processes.
The STM8L151x4/6 architecture is designed for embedded control rather than high-compute workloads. Its Flash memory supports firmware storage, while the 2 KB SRAM provides working memory for control logic, state variables and peripheral buffers. Operating at up to 16 MHz provides sufficient processing bandwidth for digital control, sensor aggregation, human-interface input, communication tasks and supervisory functions without requiring a higher-complexity MCU.
Typical uses include low-power sensor controllers, compact industrial control modules, battery-operated instruments, LCD-oriented control panels, access-control terminals and small automation nodes. The 1.8 V minimum operating voltage supports low-energy system architectures, while the 3.6 V maximum accommodates conventional 3.3 V equipment when the designer applies suitable decoupling and verifies absolute maximum limits.
Designers should preserve the STM8L151x4/6 power and peripheral configuration during firmware bring-up, including clock initialization, flash programming, GPIO assignment and low-power mode transitions. Component availability, complete electrical characteristics and exact pin functions should be confirmed against the current STMicroelectronics datasheet before a production layout is released.
This product record combines verified distributor specifications, an official manufacturer resource, comparison data and engineering-oriented application guidance. It also distinguishes genuine package-compatible options from broader functional alternatives, helping procurement and design teams evaluate replacement risk without relying on part-name similarity alone.

主な用途
STM8L151K6T6 の用途: 6 件s: Low-Power Sensor Controller, Compact Industrial Control Module, Battery-Operated Measurement Instrument, LCD-Oriented Human Interface, Access-Control and Security Terminal, Small Automation Node.
Low-Power Sensor Controller
The STM8L151K6T6 fits compact sensor nodes that periodically sample inputs, perform local filtering and sleep between updates. Its 16 MHz clock provides useful control headroom, while 32 KB Flash and 2 KB RAM are sufficient for embedded firmware, configuration tables and short communication routines. The 1.8 V to 3.6 V operating range supports low-voltage battery architectures. A practical design can use the timers for periodic wake-up, but the final sleep current and wake-up latency must be measured because those values are not present in the supplied excerpts.
おすすめ
Compact Industrial Control Module
STM8L151K6T6 is appropriate for small industrial control modules that combine digital inputs, status indicators, timers and low-speed serial communication. Its 8-bit STM8L architecture keeps firmware and system complexity economical, while the 32-pin LQFP package exposes more pins than a small leadless package and remains suitable for automated PCB assembly. The 3.3 V-compatible upper supply limit supports conventional industrial logic. Engineers should retain adequate input filtering, supply decoupling and ESD protection, and should validate operation across the complete temperature range required by the end equipment.
おすすめ
Battery-Operated Measurement Instrument
The STM8L151K6T6 can serve as the control processor in a battery-operated measurement instrument that acquires sensor data, performs local calculations and records results. Its low-power-oriented STM8L EnergyLite architecture, 1.8 V minimum supply voltage and 16 MHz processing capability balance responsiveness with energy awareness. Flash accommodates firmware and calibration data, while the 2 KB RAM is suitable for working buffers. Run-time estimates should include radio, display and sensor activity because the supplied data does not provide the device's detailed current-consumption or standby-mode characteristics.
おすすめ
LCD-Oriented Human Interface
STM8L151K6T6 fits LCD-oriented control panels that need menu handling, button input, status feedback and periodic refresh. The available family description identifies LCD support, RTC and timers, allowing a single low-cost MCU to consolidate user-interface and supervisory tasks. At 16 MHz, the processor can service display updates and control logic without a complex external controller. The 32-pin LQFP footprint provides a practical route for connecting a display and controls. Exact LCD timing, GPIO alternate functions and segment counts must be checked against the manufacturer pin and peripheral tables before schematic capture.
おすすめ
Access-Control and Security Terminal
STM8L151K6T6 can coordinate credential input, lock or relay control, event logging and communication in an access-control terminal. Its 8-bit architecture and 32 KB Flash are appropriate for embedded supervisory logic, while timers can support keypad scanning and timing tasks. The 1.8 V to 3.6 V range permits integration with low-voltage power systems, although security functions such as cryptographic authentication are not established by the supplied excerpts. A production design should add appropriate tamper detection, credential protection and fail-safe actuator behavior rather than treating general-purpose MCU suitability as a security certification.
おすすめ
Small Automation Node
The STM8L151K6T6 is suitable for distributed automation nodes that monitor digital or analog-facing circuitry and report system status over a low-speed interface. The MCU's 32 KB Flash and 2 KB RAM are adequate for compact supervisory software, and its timers support periodic sampling and timeout management. The 32-LQFP package makes the design straightforward to inspect, rework and route on cost-sensitive control boards. For motor, relay or high-energy actuator outputs, the STM8L151K6T6 should control separate protection and driver circuitry rather than switching loads directly.

主な差別化要因

- Documented 2 KB RAM configuration （vs STM8L151C6T6)
設計ノート
Plan the STM8L151K6T6 power tree around its verified 1.8 V to 3.6 V operating range. Place the closest decoupling capacitors at the device supply pins, maintain a low-resistance return path and separate sensitive analog or timing paths from switching-node currents. The supplied data does not include detailed current-consumption curves, so battery and thermal budgets must be completed from the current manufacturer datasheet rather than assumed from the family description.
Use the 32-pin LQFP land pattern from the official STMicroelectronics package drawing and verify it against the PCB library before release. Provide accessible routing for programming and production test, and preserve the exposed perimeter leads required for soldering and inspection. Although the package is 7 mm x 7 mm, lead width, pitch, toe geometry and courtyard must come from the manufacturer drawing rather than from the abbreviated distributor package description.
Do not treat a related STM8L part as an automatic firmware-compatible replacement. Check every pin, alternate-function mapping, clock setting, timer channel, communication peripheral and memory requirement, then rebuild and regression-test the firmware. The cross-reference candidates are screened to the LQFP-32 class, but the supplied excerpts do not establish identical register sets, so blind substitution can create boot failures or peripheral conflicts.
Assign oscillator, reset and high-speed clock-related routes before general-purpose GPIO placement because early pin selection can prevent later routing changes. Keep switching-regulator and high-current actuator paths away from the MCU supply loop and communication lines. If the design uses RTC, timer inputs or LCD signals, account for their pin availability during schematic design and avoid assigning the same physical pin to incompatible peripheral functions.
コンプライアンス情報
