Product details

16 MHz 8-bit MCU with AEC-Q100 — what it was designed for

Peripheral set and connectivity — LIN, UART, SPI, I²C

Obsolete — no direct successor on record

No official replacement part number is listed in the STM8A series, so a buyer looking to fill a BOM line will need to source through the surplus and broker channel. The 32-LQFP footprint and AEC-Q100 qualification narrow the search for a pin-compatible substitute — any candidate must match the 7x7 mm body, the supply range, and the automotive temperature grade.

Frequently asked questions

What is the replacement for STM8AF6226TAY?

No official replacement part number is listed by STMicroelectronics for this MCU. A functionally similar AEC-Q100 8-bit MCU in a 32-LQFP package with at least 8 KB Flash, 1 KB RAM, and LIN/UART connectivity would be the closest substitute, but pin compatibility must be verified against the board layout.

What are the specifications of STM8AF6226TAY?

It is an 8-bit STM8A core running at 16 MHz, with 8 KB Flash, 1 KB SRAM, and 640 bytes of EEPROM. It is AEC-Q100 qualified.

What is the difference between STM8AF6226TAY and STM8AF6226?

The base STM8AF6226 part number covers the same core and memory, but the exact package and temperature options may differ. Always compare the full order code against the BOM's footprint and environmental requirements.
