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.

STM8S005K6T6C

STM8S005K6T6C - 16MHz 8-Bit MCU, 32KB Flash, LQFP-32 | STMicroelectronics

The STMicroelectronics STM8S005K6T6C is a value-line 8-bit microcontroller (MCU) with a 16 MHz core, 32 KB of Flash program memory, 2 KB of RAM and 128 bytes of data EEPROM, packaged in a 32-pin LQFP (7x7 mm). It is the 32-pin member of the STM8S005C6/K6 family and is intended for cost-sensitive, high-volume embedded control designs. What is an 8-bit value-line microcontroller? An MCU is a complete single-chip computer: a CPU core, program Flash, data RAM, embedded EEPROM, and on-chip peripherals on one die. The "value line" designation means ST optimized the STM8S005 for low cost and low power rather than for maximum performance or peripheral count. In the hierarchy it sits as: 8-bit MCU -> embedded microcontroller -> general-purpose IC -> semiconductor. The 8-bit core naturally handles small state machines, sensor conditioning, key scanning, and actuator control where 16- or 32-bit processing is unnecessary. Key features include a maximum 16 MHz core clock, 32 KB Flash, 2 KB SRAM, 128 bytes of EEPROM, a 10-bit successive-approximation ADC, and the ST 8-bit peripheral set: one UART, one SPI interface, one I2C interface, 16-bit timers with PWM channels, and an internal 8 MHz RC oscillator with external clock support. All timers can be clocked from the internal RC source, allowing cost savings on the crystal/ceramic resonator. Architecturally the STM8S005 core uses a single-cycle Harvard architecture with an 8-bit data bus, so Flash is accessed in a single cycle and the pipeline executes most instructions in one to three cycles. This gives real-world performance well above what the 16 MHz headline number suggests for typical control code. On-chip debug and programming are handled through the standard ST 8-bit debug interface (SWIM plus optional SWD on related devices), and the toolchain is the free ST-LINK / STM8CubeProgrammer ecosystem. Typical applications include small home appliances, kitchen and white-goods control boards, simple sensor-hub nodes, LED and lighting controllers, toys, security keypads, and low-cost industrial control modules where a small pin count and low unit cost matter more than processing headroom. One design consideration dominates: this is a 32-pin LQFP, so GPIO and peripheral breakout is modest. Plan pin multiplexing for I2C, SPI, and UART carefully before finalizing the PCB, and confirm the ADC reference and operating supply range in the manufacturer datasheet before committing to a power rail. This page consolidates manufacturer specifications, package and pinout detail, drop-in replacement options, and practical design notes so you can qualify the STM8S005K6T6C for a new design or a board repair without piecing together information from multiple sources.

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.

STM8S103F3P6

STM8S103F3P6 - 8-bit 16MHz MCU, 8KB Flash, 20-TSSOP | STMicroelectronics

The STMicroelectronics STM8S103F3P6 is an access-line 8-bit microcontroller from the STM8S family, featuring a 16 MHz STM8 core, 8 KB of Flash program memory, and an integrated true data EEPROM, housed in a 20-pin TSSOP package. The device delivers 1 Kbyte of SRAM, a 10-bit ADC, three 16-bit timers, plus UART, SPI, and I²C communication interfaces, with 16 programmable I/O pins for general-purpose use. Operating from a 2.95 V to 5.5 V supply, the STM8S103F3P6 provides a balance of small footprint, low power, and rich peripherals for cost-sensitive embedded designs. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripheral interfaces. The STM8 core uses an advanced Harvard architecture with a 16-bit instruction word and 32-bit program counter extension for efficient code density. The "Access line" designation indicates this part targets cost-optimized designs with sufficient peripherals for general control tasks. This positions the STM8S103F3P6 within the broader taxonomy: MCU -> 8-bit microcontroller -> STM8 family -> STM8S access line -> STMicroelectronics 8-bit portfolio. Key features include 8 KB Flash with in-application programming (I2AP) capability, 640-byte true data EEPROM rated for 300 k write/erase cycles, a 10-bit ADC with up to 5 channels, and a 4-channel 16-bit PWM/timer structure supporting capture, compare, and one-pulse modes. The integrated SWIM debug interface and on-chip watchdog with window option simplify development and field reliability. The 20-pin TSSOP package offers a compact 6.5 mm × 4.4 mm footprint suitable for space-constrained PCBs. Typical applications include low-cost consumer appliances, sensor interface nodes, LED lighting controllers, battery chargers, simple motor drivers, and replacement of legacy 8051 or PIC16 designs. The wide 2.95-5.5 V supply range also supports 3.3 V and 5 V industrial systems without level shifters. Designers should note that the STM8S103F3P6 (industrial grade, -40 °C to 85 °C) and the STM8S003F3P6 differ in feature set; the '103 part includes a beeper and AWU peripherals absent on the '003. For higher memory needs, the STM8S105 series provides 32 KB Flash in larger packages. This page synthesizes distributor pricing, drop-in alternatives, and design notes not found in the manufacturer datasheet alone.
