STM8S003K3T6

STM8S003K3T6 - 8-bit 16MHz MCU, 8KB Flash | STMicroelectronics

The STMicroelectronics STM8S003K3T6 is an 8-bit value-line STM8S microcontroller featuring a 16 MHz advanced STM8 core, 8 KB of Flash program memory and 128 bytes of true data EEPROM, housed in a 32-pin LQFP (7x7 mm) package. According to the manufacturer datasheet, the device integrates a 10-bit ADC, three general-purpose 16-bit timers, a UART, SPI and I2C communication interfaces, plus independent watchdog timers with separate clock source for safety-critical applications. The chip operates from 2.95 V to 5.5 V supply and is built on ST's state-of-the-art 130 nm embedded Flash process. A value-line microcontroller (often called an 8-bit MCU) is a small, low-cost processor optimised for embedded control tasks such as sensor reading, motor actuation, indicator driving, and user-interface handling. Within the broader semiconductor hierarchy, an MCU is a subset of microprocessors (MPU) and is differentiated by integrated Flash, RAM and peripherals on a single die. The STM8S003K3T6 occupies the entry-level value-line of the STM8S family, balancing die size, peripheral set and price for cost-sensitive designs where a 32-bit MCU is unnecessary. Key features that differentiate the STM8S003K3T6 in its class include 1 KB of RAM, the integrated 10-bit SAR ADC with up to 5 multiplexed channels, the clock security system (CSS) that detects external clock failure and switches to the internal RC oscillator, plus 100 k write/erase cycle endurance on the data EEPROM. Robust I/O design tolerates 5 V injection on adjacent pins, simplifying mixed-voltage interface to legacy 5 V peripherals. The 32-pin LQFP-32 (7x7) footprint provides easy hand-soldering and breadboard prototyping versus fine-pitch QFN options. Technically, the STM8S003K3T6 is engineered around the proprietary STM8 core with 16-bit index registers and a 20-bit program counter, executing most instructions in 1-2 clock cycles. The integrated voltage regulator and brown-out reset (BOR) circuitry protect the Flash against low-voltage write corruption. The 16 MHz system clock can be sourced from an external crystal, resonator, or the factory-trimmed internal 16 MHz RC oscillator with ±1 % accuracy across the full operating temperature range. Typical applications include low-cost consumer appliances (rice cookers, washing-machine user interfaces, induction cooktops), battery-powered sensor nodes, LED lighting controllers, simple BLDC/PMSM auxiliary motor drivers (fans, pumps), 5 V industrial control buttons, and Arduino-Nano-compatible hobbyist boards. The wide 2.95-5.5 V supply range and proven STM8 toolchain (STVD, IAR, Cosmic, SDCC) make it a frequent second source for legacy 8051 designs requiring a software refresh. When designing with the STM8S003K3T6, choose between the internal 16 MHz RC oscillator (saves BOM cost) and an external crystal (better UART baud-rate accuracy). Decouple VDD/VSS with 100 nF ceramic capacitors placed within 3 mm of each supply pin, and reserve the SWIM pin (single-wire debug) for in-circuit programming. For noisy environments, enable the CSS and the window watchdog for IEC 60730 class B compliance. This page synthesizes distributor pricing, drop-in alternatives and practical design notes not found in the manufacturer datasheet, and is intended as a faster reference than the 31-page ST datasheet for engineers evaluating the part for production.

When designing, verify the exact pin assignments, alternate-function selection, clock configuration, ADC input availability, and peripheral instance mapping from the STMicroelectronics datasheet. Place decoupling capacitors close to the supply pins and keep high-current or switching nodes away from sensitive analog inputs. Program the device with a compatible STM8 toolchain and validate startup, reset, clock, and watchdog behavior on the final PCB. This page synthesizes the verified manufacturer and distributor information, package details, application guidance, and engineering considerations for engineers evaluating the STM8S103F2M6. It emphasizes exact-ordering-code verification rather than assuming every STM8S103F2 family variant has identical resources.

The verified product information identifies a 2.95 V to 5.5 V supply range, 16 I/O ports, integrated true data EEPROM, and an 8 KB Flash organization of 8K × 8. Its lifecycle status is active. A microcontroller is a programmable semiconductor device that integrates a processor core, memory, and peripherals into one compact component. In the device hierarchy, the STM8S103F3 belongs to the STM8S 8-bit MCU family, a cost-conscious platform for embedded control. The STM8S103F3M6 is intended for products that need deterministic low-complexity control, local sensing, actuator output, and communication without adopting a higher-cost 32-bit MCU. The principal verified features include a 16 MHz clock, 8 KB Flash memory, true EEPROM, 16 I/O ports, and operation across a 2.95 V to 5.5 V supply range. The true data EEPROM is useful when persistent parameters must be retained outside the program Flash. Sixteen I/O ports give a compact design multiple digital connection points, while the 20-pin SOIC package supports conventional surface-mount assembly. The access-line positioning emphasizes general embedded utility rather than automotive qualification or extreme-performance processing. The STM8S architecture is suited to small control loops, keypad interfaces, indicator logic, sensor conditioning, and communication modules. Because only Flash memory and clock speed were explicitly quantified in the supplied verified results, detailed RAM, peripheral, timer, and electrical limits should be confirmed in the manufacturer documentation before design release. Firmware migration also requires reviewing the applicable STM8S103F3 device datasheet, reference manual, startup files, linker configuration, and toolchain settings. Typical applications include building controls, compact industrial interfaces, appliance controllers, instrumentation, and low-power sensor nodes. At 16 MHz, the MCU can service multiple time-sensitive I/O tasks while keeping the design centered on an economical 8-bit processor. Its 8 KB Flash capacity also makes it most appropriate for applications with modest code requirements and simple update behavior. Designers should confirm every peripheral assignment, alternate-function mapping, pin type, and electrical limit from the official STM8S103F3M6 documentation before PCB release. Decoupling, clock stability, programming access, and exposed-pin assignments must follow the manufacturer recommendations. This page combines verified distributor and manufacturer information with procurement context and engineering guidance rather than filling missing technical details with assumptions. The information below synthesizes official product positioning, distributor listings, verified pricing evidence, and application-specific design considerations. Missing RAM, timer, peripheral, and package details are intentionally marked for verification, preventing unsupported claims from entering a new design.

STM8S103F3P3

STM8S103F3P3 - 16MHz 8-Bit MCU, 8KB Flash | STMicroelectronics

The STMicroelectronics STM8S103F3P3 is an access-line, 8-bit STM8S microcontroller rated up to 16 MHz, with 8 Kbytes of Flash program memory, integrated true data EEPROM, and a 20-TSSOP package. It combines a 10-bit ADC, three timers, UART, SPI, and I2C interfaces in a compact surface-mount package suitable for cost-sensitive embedded control systems. The device operates from a 3.3 V or 5 V supply according to the verified distributor specifications. An STM8S microcontroller belongs to the 8-bit embedded-microcontroller hierarchy, where an MCU integrates a CPU core, program memory, data memory, peripherals, and interface logic on one semiconductor die. The STM8S103F3 access line is positioned for compact embedded applications where a modest processing rate, useful analog measurement, and multiple serial interfaces are more important than high-bandwidth computation. Its integrated true data EEPROM also allows frequently changed calibration or configuration data to be stored separately from program Flash. Three principal characteristics define this device: a maximum 16 MHz operating frequency, up to 8 Kbytes of Flash program memory, and a 10-bit ADC. The STM8S103F3P3 additionally provides three timers and UART, SPI, and I2C serial interfaces. These resources allow a design to measure analog inputs, control timing-dependent outputs, and communicate with sensors, transceivers, displays, or external nonvolatile memories without requiring several separate interface devices. The STM8S103F3P3 uses STMicroelectronics' STM8 8-bit architecture and is associated with the STM8S103F2/x3 access-line family. At 16 MHz, the device provides substantially more timing headroom than an 8 MHz-class MCU while retaining the straightforward programming model and integrated peripherals expected from an entry-level 8-bit platform. The available verified information does not specify RAM size, ADC resolution details beyond 10-bit capability, or individual peripheral timing ratings, so those details should be confirmed in the manufacturer datasheet before timing-critical design work. Typical uses include compact industrial controllers, appliance control boards, sensor acquisition modules, motor or actuator controllers, communication gateways, and low-cost consumer products. The three timers support periodic control and timing functions, the 10-bit ADC supports analog sensing, and UART, SPI, and I2C cover common embedded communication requirements. The 20-TSSOP package is particularly useful where a through-hole footprint is unnecessary but a fine-pitch surface-mount assembly is available. PCB implementation requires careful decoupling of each supply pin and a low-impedance connection between the MCU and its crystal or clock source when an external resonator is used. Firmware must preserve the device-specific reset, boot, and oscillator options, and peripheral inputs must remain within the electrical limits published by STMicroelectronics. Because the verified distributor result explicitly describes the STM8S103F3P3 as packed in a tube, procurement should use the manufacturer ordering information to confirm the shipping quantity and marking treatment. This page combines the verified STMicroelectronics family information with distributor pricing, package details, selection guidance, and practical design considerations. It distinguishes confirmed capabilities from parameters that still require datasheet verification, helping engineers identify the STM8S103F3P3 for compact, mixed-signal embedded-control designs without treating unverified electrical details as guaranteed specifications.

The C4T3 ordering identifies a device with 16 KB of Flash in the STM8S105C4 configuration and the 48-LQFP package. The 16 MHz operating speed is suitable for motor-control peripherals, communications, consumer accessories, industrial controllers, and embedded products that do not require a high-performance 32-bit core. The 38 available I/O pins make the 48-LQFP package useful when a design needs multiple control and monitoring signals while preserving a modest footprint. Available resources described by the verified data include 2 KB of RAM, integrated EEPROM, and the STM8S105xx access-line feature set. Detailed clock-tree options, ADC characteristics, timer resolutions, supply limits, and package thermal parameters were not included in the supplied search records and therefore require confirmation from the official manufacturer datasheet before design release. Typical applications include small motor controllers, sensor-hub boards, communication modules, panel interfaces, appliance controls, and compact industrial automation products. The 16 MHz core and 16 KB Flash are particularly useful for control loops and protocol state machines, while the 38 I/O pins simplify peripheral connection compared with smaller packages. Designers should confirm the complete 48-pin assignment, oscillator requirements, reset behavior, peripheral pin multiplexing, and electrical limits from the official STM8S105 datasheet. PCB layouts should preserve decoupling and exposed-pad thermal requirements where applicable, and firmware must account for alternate-function reassignment when using the numerous I/O pins.

It includes an embedded debug module (SWIM) for in-circuit debugging and programming, and a single-wire interface for firmware updates. The CAN controller supports CAN 2.0B active mode, enabling robust industrial networking. The device is manufactured using ST's proprietary 130nm process, balancing performance and power efficiency. Typical applications include industrial control systems, home appliances, automotive body electronics (non-safety), sensor nodes, and communication gateways. The CAN interface makes it particularly suitable for automotive and industrial CAN bus networks, while the multiple UARTs and SPI/I²C support diverse peripheral connectivity. When designing with this MCU, ensure proper decoupling of the VDD and VDDA pins with 100nF capacitors placed close to the pins. The SWIM pin should be pulled up with a 10kΩ resistor for reliable programming. For CAN applications, an external CAN transceiver (e.g., TJA1050) is required, and the bus termination resistor should be 120Ω at each end of the CAN bus.

STM8S207R6T6 - 24MHz 8-Bit MCU 32KB Flash LQFP-64 | STMicroelectronics

The STMicroelectronics STM8S207R6T6 is a performance-line 8-bit STM8S microcontroller built around a CISC Harvard architecture core running at 24 MHz (20 MIPS) with 32 KB of on-chip Flash program memory and up to 2 KB of SRAM plus an integrated EEPROM data area. It integrates a 10-bit ADC, two 16-bit timers plus one 8-bit timer, two UARTs, SPI, I2C, and CAN, all in a 64-pin LQFP (T6 suffix) package operating from 2.95 V to 5.5 V. The device is positioned in the STM8S20xxx family which scales from 32 KB to 128 KB Flash and is intended for cost-sensitive motor-control, appliance, and industrial-control applications. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripherals onto one silicon die. The STM8 family uses a CISC 8-bit core with a 16-bit instruction word, giving higher code density than legacy 8051 cores while retaining the predictable interrupt latency and deterministic timing that embedded control designers prefer. The STM8S207 series specifically belongs to the STM8S "performance line," sitting above the access-line STM8S103 and below the value-line STM8S105, and is paired with ST's Cosmic, IAR, and Raisonance toolchains plus the free STVD development environment. Key features of the STM8S207R6T6 include a 20 MIPS peak instruction throughput at 24 MHz, integrated CAN 2.0B interface, a 1 Mbyte linear address space, a single-wire SWIM debug interface, and an embedded bootloader stored in ROM for in-application Flash programming. The device offers 38 GPIOs with 5 V tolerance on most pins and supports up to 16 external interrupts. Watchdog, auto-wakeup, and a 4-level low-power run/wait/slow/halt scheme allow the device to drop quiescent current below 5 uA in Halt with full RAM retention. Architecturally, the STM8S core pairs a 32-bit program address bus with a 24-bit data address bus and supports up to 16 Mbytes of linear addressing for data, while code is read from a separate Flash bus. This Harvard split removes fetch-decode stalls that plague older 8-bit Von Neumann designs and is the reason the family reaches 20 MIPS at 24 MHz without wait states. A 32 KB Flash variant such as the STM8S207R6 sits at the low-memory end of the family, sharing the same peripheral set as the larger 64 KB (R8) and 128 KB (RB) siblings. Typical applications include BLDC/PMSM motor control in appliances, HVAC fan and pump control, smart metering, lighting ballast control, industrial sensor hubs, and CAN-connected remote I/O nodes. The integrated CAN controller, combined with 32 KB Flash, makes the part a good fit for distributed industrial nodes that need deterministic on-chip comms without an external transceiver MCU. When designing with the STM8S207R6T6, pay attention to the 5 V I/O tolerance (most pins are true 5 V tolerant, but a few high-current pins are FT-compat only) and to the SWIM pin shared with NRST; the debug probe needs a tri-state buffer on the SWIM line for in-circuit debugging without disabling reset. The internal 16 MHz HSI RC is accurate to about 1 percent after user trimming, but designs that need CAN bit-time accuracy must select the external HSE crystal option.

STM8S207RBT6 - 24MHz 128KB 8-Bit MCU | STMicroelectronics

The STMicroelectronics STM8S207RBT6 is an 8-bit STM8S performance-line microcontroller with a 24 MHz maximum CPU frequency, 128 KB of Flash program memory, 20 MIPS performance, and a 64-pin LQFP package measuring 10 x 10 mm. It is designed for embedded control applications requiring integrated communications, mixed-signal measurement, and broad peripheral support. An 8-bit microcontroller is a compact embedded computing device that executes firmware from nonvolatile Flash memory while using timers, serial interfaces, and analog inputs to control a target system. The STM8S207RBT6 belongs to the STM8S performance-line hierarchy of 8-bit RISC microcontrollers, combining an advanced Harvard-architecture core with integrated EEPROM, analog, timing, and communication peripherals. Key features include a maximum CPU frequency of 24 MHz, 128 KB of Flash, a three-stage pipeline, a 10-bit ADC, two UARTs, SPI, I2C, and CAN connectivity. According to the STM8S207RBT6 product information, these peripherals allow the device to consolidate functions that would otherwise require separate interface and conversion ICs. The LQFP-64 package also provides numerous general-purpose I/O pins for external sensing, actuation, and communication connections. The STM8 core uses Harvard architecture, separating instruction and data access paths, while the three-stage pipeline supports efficient instruction throughput. At the maximum 24 MHz operating frequency, the device delivers up to 20 MIPS. Integrated EEPROM supports parameter and configuration storage, although its exact capacity must be confirmed from the complete manufacturer datasheet before it is reserved in firmware. Typical applications include industrial controllers, motor-control and automation equipment, communication modules, building-control interfaces, consumer appliances, and compact embedded control panels. CAN, SPI, I2C, and UART support is particularly useful for systems that must connect sensors, actuators, human-interface modules, or service buses while retaining a compact embedded-control architecture. Designers should verify the complete 64-pin pinout, peripheral alternate-function mappings, clock configuration, and decoupling requirements against the manufacturer datasheet. The 10 x 10 mm LQFP footprint is easy to inspect after soldering, but its fine-pitch leads still require careful land-pattern and paste-volume control for reliable assembly. This product page consolidates verified manufacturer and distributor information, package details, sourcing data, application guidance, and temperature-grade replacement options into an engineering-focused reference. It distinguishes exact drop-in options from broader functional comparisons so designers can make a package- and pin-compatible selection without overlooking software or qualification constraints.
