STM8AF6223PAX

STM8AF6223PAX is an 8‑bit microcontroller from STMicroelectronics, part of the STM8 AF family. It targets low‑power, cost‑efficient embedded control with on‑chip flash, RAM, and a rich peripheral set. Features typically include an STM8 8‑bit core running up to tens of MHz, I/O ports, timers, ADC, and communication interfaces such as USART/SPI/I2C, plus standard power‑management modes. The PAX suffix identifies the device’s package type and temperature grade. Applications include general embedded control in consumer, industrial, and automotive segments where reliable, small-footprint MCUs are needed. For precise specs—flash/RAM size, pin count, operating voltage, clock speed, package outline, and temperature range—see the official STM8AF6223PAX datasheet on ST’s website. Toolchain support is available from ST’s development tools and third‑party IDEs, with HAL/LL driver libraries provided by ST.

Pin count: 20 pins (PAX package).
Function: 8-bit STM8 microcontroller (STM8AF62x family) with on-chip Flash/RAM and peripherals (GPIOs, timers, ADC, and standard serial interfaces such as UART, SPI, and I2C) for embedded control.

- Manufacturer: STMicroelectronics (ST).
- What kind of company: A multinational electronics and semiconductor company that designs, manufactures, and sells a broad range of semiconductor devices and components (including microcontrollers like the STM8 family) for automotive, industrial, consumer, and other markets. Headquarters in Geneva, Switzerland, with global operations.

Here are typical application areas for the STM8AF6223PAX:
- Automotive body electronics and sensor interfaces
- Industrial automation, control panels, and instrumentation
- Home/building automation: lighting, HVAC, security, meters
- Consumer electronics and small appliances (remote controls, UI/controllers)
- IoT and battery-powered sensor nodes
- Motor control for small DC motors/stepper devices
These 8‑bit MCUs are suited for cost-effective, low‑to‑mid‑complexity embedded tasks with moderate peripherals and power efficiency.

It uses a plastic Small Outline package, 20 pins (SO-20). The PAX suffix denotes the plastic SO package.
