Product details

The STM8AF62A6UDX is an automotive-grade 8-bit MCU from the STM8A series, built around the STM8A core at 24 MHz.

Peripheral set and I/O budget

With 25 I/O lines in a 32-pin package, the STM8AF62A6UDX gives you a good ratio of usable pins to package size. The on-chip peripherals include a 7-channel 10-bit ADC, multiple timers with PWM, a watchdog timer, brown-out reset, and POR — enough for sensor readout, actuator PWM, and basic fault supervision without external supervisor ICs. Connectivity covers I²C, LINbus (for automotive body networks), SPI, and UART/USART, so it can talk to a CAN transceiver, a LIN transceiver, or a local sensor hub.

Frequently asked questions

What is the closest pin-compatible alternative to STM8AF62A6UDX in this component family?

The STM8A family shares the same 32-VFQFPN 5x5 mm footprint across many density options. An active STM8A part with matching pinout and peripheral set should be selected from ST's current product selector — the exact order code depends on the Flash/RAM/EEPROM size and temperature grade required for your application.

What is STM8AF62A6UDX's listed speed (24 MHz) on this component line?

The core runs at 24 MHz maximum. That is the CPU clock speed — the internal oscillator or external clock source feeds the STM8A core; the peripherals (timers, ADC, serial interfaces) run at that clock or a divided-down rate. For timing closure, budget for the 24 MHz instruction cycle (about 41.7 ns per machine cycle) when calculating loop times or PWM resolution.

What is STM8AF62A6UDX's listed series (Automotive, AEC-Q100, STM8A) on this component line?

It is part of the STM8A series, which is ST's automotive-qualified 8-bit MCU line. AEC-Q100 Grade 0 (or equivalent) qualification means it passes the stress tests for under-hood operation — the -40°C to 150°C range covers the full automotive temperature envelope, including hot soak conditions near the engine or exhaust.

What compliance documentation does this brand provide for STM8AF62A6UDX (RoHS, REACH, UL, IEC)?

STMicroelectronics provides RoHS and REACH compliance declarations for the STM8A series. The part is lead-free and RoHS-compliant per ST's standard material declaration. UL and IEC certifications are not typical for individual MCUs — those apply at the module or system level. Contact our team if you need a specific compliance certificate for your quality file.
