The STM8AL3L68TAY from STMicroelectronics is an 8-bit STM8 microcontroller running at 16MHz. It provides 32KB flash and 2KB SRAM, with a supply range of 1.65V to 3.6V. The 48-LQFP package includes brown-out detect, DMA, POR, PWM, and WDT, optimized for low-power and portable applications.

  • Ultra-low 1.65V supply – maximizes battery utilization in portable designs.
  • Compact 48-LQFP – balances I/O count with board space.
  • Integrated brown-out detect – prevents data corruption during power dips.
  • 16MHz efficient core – sufficient for control loops with minimal power draw.

Wearable Health Monitors

1.65V operation and small 48-LQFP enable compact, low-power biosignal sensing.

Smart Agriculture
