The STMicroelectronics STM8AF52A9TAY is an 8-bit MCU from the STM8A automotive series, built around the STM8A core running at 24 MHz.
Brown-out detect and POR are integrated, so the reset circuit on the board can be minimal.
If you are starting a new design, ST's current automotive MCU families (STM8A successor lines or STM32A) should be evaluated for form-fit-function compatibility.
It is still available for production and repair orders through the channel, but new designs should target a current automotive MCU family.
The two order codes are electrically identical. The suffix 'TR' indicates tape-and-reel packaging; the base STM8AF52A9TAY ships in tray format. Pinout and all parametric ratings are the same.
