STM8AF52A6UCY

STM8AF52A6UCY is an STMicroelectronics 8‑bit microcontroller from the STM8AF52A6 family. It combines the STM8 8‑bit CPU core with on‑chip flash and RAM and a rich set of peripherals for embedded control.
Key points
- Core and memory: STM8 8‑bit architecture with program flash and RAM (sizes vary by variant; check datasheet for exact numbers).
- Peripherals: multiple USARTs (serial), SPI, I2C, general‑purpose timers, ADCs (and sometimes DAC), analog comparators, watchdog/RTC, and various I/O options.
- Power and clock: designed for low‑to‑mid power applications; operating voltage and maximum clock depend on the exact variant.
- Package: UCY suffix indicates a specific physical package option (check datasheet for pin count and form factor).
- Development: supported by ST development tools (STVD/IAR/Cosmic in the past, newer toolchains with ST libraries), and programming/debug via ST‑Link.
Typical use: embedded control in automotive, consumer electronics, sensors, and small motor/automation tasks.
For exact specs (flash/RAM size, peripherals, voltage, clock, and package), consult the STM8AF52A6UCY datasheet and reference manual.

There isn’t a direct external equivalent to the STM8AF52A6UCY. The closest substitutes are other ST STM8 variants (same core family in different packages) or other STM8A/STM8S devices with similar memory/peripherals. For exact substitutes, use ST’s Cross Reference/Substitution tool; external vendors usually do not offer a one‑for‑one cross.
