- Integrated non-volatile memory with industrial-grade data retention specifications
- Comprehensive peripheral set including analog-to-digital conversion and serial communication interfaces
- Multiple low-power operating modes to optimize energy consumption
Applications
- Battery-powered embedded systems requiring low active current
- Industrial control applications utilizing the industrial temperature range
- Sensor interface designs leveraging the integrated 10-bit ADC
- Communication nodes using SPI or TWI protocols
Procurement Notes
Verify the specific ordering suffix 'R' indicates tape and reel packaging when sourcing this component. Confirm that the speed grade corresponds to the required operational frequency for your target voltage and temperature conditions. Ensure compatibility with existing development tools and programming interfaces before finalizing procurement decisions.
Selection Notes
Select this model for designs requiring a compact 14-pin SOIC footprint with sufficient I/O lines for basic peripheral control. Consider the 12 MHz speed grade if operating within the 4.5V to 5.5V voltage range. Evaluate the power consumption characteristics against system requirements, particularly for idle and power-down modes.
Part Context
This component belongs to the ATtiny family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares architectural similarities with other devices in the series but offers specific memory sizes and package options tailored for cost-sensitive and space-constrained applications.
Replacement Considerations
Consult official documentation for cross-references. Verify pinout compatibility and electrical specifications when substituting with other ATtiny variants.
