The Microchip ATTINY13A-SF is an 8-bit AVR MCU in an 8-SOIC package. It delivers 20MHz with 1KB flash and 64B SRAM. Its 1.8V-5.5V range and -40°C to 125°C rating make it ideal for extreme environments. Integrated PWM, Brown-out Reset, and WDT provide robust control.

  • Extended temperature range: -40°C to 125°C for harsh conditions.
  • Low 1.8V operation: supports single-cell battery designs.
  • Compact 8-SOIC: fits small PCBs.
  • AVR efficiency: fast wake-up and low power for battery life.

High-Temperature Industrial Sensors

125°C rating allows placement near engines or furnaces for temperature monitoring.

Automotive Engine Bay Modules

Wide temp range and 5.5V operation handle vibration and heat in sensor interfaces.

Miniature LED Drivers

1KB flash and PWM drive small indicator LEDs in compact enclosures.

Battery Protection Circuits

1.8V operation monitors cell voltage in single-cell Li-ion packs.

Smart Switches

WDT and POR ensure reliable toggle behavior in home automation.

Simple Motor Controllers

PWM controls small vibration motors in haptic feedback devices.
