STM8AF5286UDX

Microcontrollers Overview

The STM8AF5286UDX is an automotive-grade 8-bit microcontroller from the STM8A series, featuring a 24 MHz CPU clock and 64 Kbytes of Flash program memory. It integrates true data EEPROM with up to 300 k write/erase cycles and supports CAN communication interfaces. The device operates within a 3.3 V to 5.5 V supply range and includes internal clock oscillators, watchdogs, and brown-out reset for system robustness.

Microcontrollers Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Integrated CAN interface for automotive network communication
• High integration level with internal oscillators and reset circuits
• Robust I/O capabilities with independent watchdogs

Microcontrollers Applications

• Automotive body electronics control modules
• CAN bus gateway nodes in vehicle networks
• Engine management subsystems requiring EEPROM data retention
• Industrial controllers operating in harsh environments

Microcontrollers Procurement Notes

Verify the specific suffix UD against official STMicroelectronics documentation to confirm package type and temperature range. Ensure compatibility with existing design tools such as STVD/STVP. Confirm end-of-life status if applicable, as some STM8AF variants may be transitioning out of production. Cross-reference pinouts with reference manual RM0016 for accurate integration.

Microcontrollers Selection Notes

Select this component when automotive certification and CAN connectivity are mandatory requirements. The STM8A core offers high performance at 24 MHz while maintaining low power consumption. Consider the integrated EEPROM for applications needing frequent non-volatile data storage without external components. Evaluate pin count and peripheral availability against system constraints before finalizing the design.

Microcontrollers Part Context

This part belongs to the STM8AF automotive family, designed for high reliability in vehicle applications. It shares architectural similarities with other STM8A devices but distinguishes itself through specific memory configurations and CAN interface support. The family emphasizes scalability and long-term product longevity using advanced semiconductor technology suitable for automotive grade conditions.

Microcontrollers Replacement Considerations

Direct substitutes include other STM8AF52xx or STM8AF62xx variants with matching Flash sizes and CAN interfaces. Verify pinout compatibility and memory map alignment before substitution. Alternative packages like TCX or TAU may offer different form factors but require schematic review.
