Key features include 8 KB Flash with in-application/in-circuit programming, 128 bytes of true byte-erasable EEPROM rated for 100 k cycles, 1 KB SRAM, 5 ADC channels with 10-bit resolution and up to 12-bit oversampling, a 16 MHz internal RC oscillator calibrated to ±1%, and a 1.8 V to 5.5 V supply range. The 8-pin SOIC exposes just enough I/O to drive a handful of switches, LEDs, sensors, or a serial link, and the integrated brown-out reset and watchdog timer simplify safety-critical designs. Two 16-bit timers and one 8-bit timer provide PWM, input capture, and output compare functions for motor, LED, and timing control. Architecturally, the STM8S001J3 is a derivative of the STM8S003F3 with the same silicon die repackaged into an 8-pin SOIC, dropping most GPIOs in favor of a tiny PCB footprint. The integrated voltage regulator lets the chip run from a single 1.8-5.5 V rail without external components. With an active-mode current in the single-digit mA range and multiple low-power modes down to a few microamps, it is well suited to battery-powered gadgets and always-on sensor nodes. Typical applications include low-cost sensor interface boards, replacement of ATtiny13/ATtiny85 designs, smart LED controllers, IR remote transmitters/receivers, simple motor and fan controllers, battery chargers, and hobby/educational platforms such as the STM8 eForth project. The wide operating temperature range (-40C to +125C) and 5 V tolerance on most pins also make it viable for industrial control front-ends. When designing with this device, note that only 6 of the 8 pins are usable as GPIO because NRST and power pins are mandatory. Use the SWIM debug interface for in-circuit programming and debugging, and place a 100 nF decoupling capacitor as close as possible to the VDD pin. Compare pinout carefully against ATtiny85 migration paths before re-using existing PCB layouts.

The STMicroelectronics STM8S003F3P6 is a value line 8-bit microcontroller based on the STM8 core, running at up to 16 MHz with 8 KB of Flash memory, 1 KB of RAM, and 128 bytes of true data EEPROM in a 20-pin TSSOP package. An 8-bit microcontroller (MCU) is a single-chip computer integrating an 8-bit CPU, program memory, data memory, and programmable peripherals. The STM8S003F3P6 belongs to the STM8S series within the STM8 family, positioned below the 32-bit STM32 series in STMicroelectronics' product hierarchy and targeting cost-sensitive embedded control. Key features include 8 KB Flash with integrated true EEPROM (up to 100,000 write/erase cycles), a 10-bit ADC with 5 channels, and UART, SPI, and I2C interfaces. The device operates from 2.95V to 5.5V, supporting both 3.3V and 5V systems, with 16 programmable I/Os and 7 timers/counters including a 16-bit timer, an 8-bit timer, and watchdog timers. The STM8 core uses a Harvard-architecture 3-stage pipeline delivering 16 MIPS at 16 MHz. An internal 16 MHz RC oscillator eliminates the need for an external crystal in many designs. Low-power modes include Halt, Active-Halt, and Wait, with 3.6 mA typical in Run mode at 16 MHz and about 1 uA in Halt mode. Typical applications include home appliances, industrial control, consumer electronics, motor control helpers, and sensor interfaces. Its wide voltage range and robust I/O make it popular in white goods, power tools, and battery-powered devices, while the integrated EEPROM removes external non-volatile memory from the BOM. Design tip: decouple VDD with a 100 nF capacitor placed close to the pin. The internal RC is accurate to approximately 2%, so use an external crystal when precise timing is required. SWIM single-wire in-circuit programming simplifies firmware updates.
