The STMicroelectronics STM8AF52A8TCX is an automotive-grade 8-bit MCU in a 48-LQFP package. It runs at 24MHz with 128KB flash and 6KB RAM, operating from 3V to 5.5V. Designed for -40°C to 125°C environments, it includes brown-out detect, POR, PWM, and WDT for reliable automotive and industrial applications.
- Automotive temperature range (-40°C to 125°C) – meets AEC-Q100 requirements for harsh environments.
- 128KB flash – ample for complex automotive and industrial firmware.
- 24MHz STM8A core – efficient 8-bit performance with low power consumption.
- Integrated safety features – brown-out detect, POR, and WDT enhance system reliability.
- 48-LQFP package – balances I/O count with compact footprint.
Automotive Body Control Modules
The 125°C rating and 3V-5.5V range make it ideal for under-hood modules like window lifters and mirror controls. 128KB flash stores complex state machines.
Engine Management Sensors
Reads pressure and temperature sensors with high reliability. Brown-out detect and POR ensure safe operation during cranking voltage dips.
Industrial Motor Drives
PWM outputs drive IGBTs for 3-phase motors. The 24MHz core handles FOC algorithms with 6KB RAM for data buffers.
Smart Actuators
Integrates position feedback and limit switches. WDT prevents lockups in safety-critical valve actuators.
Off-Road Vehicle Electronics
Rugged temperature range and robust POR handle vibration and extreme heat in construction equipment.
Power Distribution Units
Monitors current and voltage, controls relays. The 48-LQFP package offers enough I/O for multiple channels.
