Automotive 8-bit MCU for harsh environments
It is built around the STM8A core and runs at up to 24 MHz.
Peripheral set for automotive control nodes
This MCU integrates a 16-channel 10-bit ADC for reading analog sensors, plus communication interfaces including I²C, LINbus, SPI, and UART/USART. The LINbus interface directly supports automotive body-networking protocols.
NRND — plan for last-time-buy or alternate
This means STMicroelectronics is phasing out the part — new designs should target a replacement, and existing production should secure final inventory or qualify a second source. The part is not yet discontinued, but the window for last-time-buy orders is open.
Housed in a 64-pin LQFP package (10x10 mm body), the STM8AF62A9TDY is a surface-mount device with 52 general-purpose I/O lines. The 0.5 mm pitch requires careful PCB routing for the I/O and supply rails. The supplier device package is 64-LQFP (10x10), matching the industry-standard footprint for mid-density automotive MCUs.
