STM8AF6388TDX

Microcontrollers Overview

The STM8AF6388TDX is an automotive-grade 8-bit microcontroller from the STM8A series, featuring a 24 MHz CPU clock and 128 Kbyte of Flash program memory. It includes 2 Kbyte of true data EEPROM and 6 Kbyte of RAM. The device supports a supply voltage range of 3V to 5.5V and operates within a temperature range of -40°C to 150°C. Connectivity options include I2C, LINbus, SPI, and UART/USART interfaces. It is housed in a 48-LQFP package with 38 I/O lines.

Microcontrollers Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust performance in vehicle environments.
• High system integration with internal oscillators, watchdogs, and brown-out reset capabilities.
• Enhanced reliability features including independent watchdogs with separate clock sources and clock security systems.

Microcontrollers Applications

• Automotive body electronics control modules
• LIN bus communication nodes
• Engine management subsystems
• Industrial motor control applications

Microcontrollers Procurement Notes

Verify the specific suffix 'D' indicates tape and reel packaging when ordering. Confirm the exact Flash capacity (128K) matches the design requirements, as this model represents the high-density variant within the STM8AF6xxx family. Ensure compatibility with the 48-LQFP footprint during PCB layout finalization.

Microcontrollers Selection Notes

Select this component for designs requiring high non-volatile memory density and automotive certification. Compare against lower-density variants like the STM8AF6288 if cost or pin count constraints exist. Verify that the 24 MHz processing speed meets the real-time execution demands of the target application logic.

Microcontrollers Part Context

This part belongs to the STM8A family, which shares a common architecture with the STM8S series but offers enhanced automotive robustness. It utilizes the advanced STM8A core with Harvard architecture and a 3-stage pipeline for efficient instruction execution.

Microcontrollers Replacement Considerations

The STM8AF6388TDX is functionally equivalent to the STM8AF6388TDX. Check for availability of the standard tube version if reel packaging is not required.
