The Microchip ATTINY167-XU is a low-power 8-bit AVR microcontroller with a 16MHz core and 16KB flash memory. It features an internal temperature sensor and operates from 1.8V to 5.5V, making it highly versatile for battery-powered and space-constrained applications. The 20-pin TSSOP package is ideal for compact PCB designs.

  • Ultra-Low Power: 1.8V operation and multiple sleep modes significantly extend battery life in portable devices.
  • Integrated Temperature Sensor: Eliminates the need for external sensors, reducing BOM cost and board space.
  • Compact Size: TSSOP-20 package is ideal for miniaturized designs.
  • Wide Voltage Range: 1.8V to 5.5V provides design flexibility across different power domains.

Battery Management Systems

The 1.8V operation and internal temperature sensor make it ideal for monitoring battery voltage and temperature in portable devices, enabling safe charging and discharging.

Sensor Nodes

With 16KB flash and low power modes, it can run periodic sensor readings and transmit data over I2C or SPI to a central hub, extending battery life in wireless networks.

Consumer Electronics

Its small TSSOP package and rich peripheral set (PWM, ADC) make it suitable for controlling LEDs, buttons, and haptic feedback in wearables or remote controls.

Automotive Interior

Rated for 85°C, it can be used in cabin lighting control or seat position memory modules, where low voltage and small size are advantageous.

Industrial Monitoring

The temperature sensor and WDT provide self-monitoring capabilities for industrial sensors, ensuring reliable operation in varying thermal conditions.

Smart Home Devices

In smart switches or thermostats, the ATTINY167 can handle user input, environmental sensing, and communication protocols, offering a cost-effective solution.
