Overview
The ATTINY28V-1AU is an 8-bit AVR microcontroller from the ATtiny28L series, manufactured by Microchip Technology. It features a 2 kB Flash program memory and operates with a maximum clock frequency of 1 MHz at 1.8 V. The device utilizes a 32-pin TQFP package and supports a supply voltage range from 1.8 V to 5.5 V. It includes 11 I/O lines and two timer/counters but lacks an ADC. The component is designed for through-hole or surface-mount applications within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates 2 kB of in-system programmable Flash memory for code storage.
- Supports low-voltage operation down to 1.8 V for energy-efficient designs.
- Includes two independent timer/counters for precise timing control.
Applications
- Low-power embedded control systems
- Simple sensor interface circuits
- Basic logic control modules
Procurement Notes
Verify the specific suffix 'AU' against official Microchip documentation to confirm the 32-pin TQFP package and commercial temperature grade. Confirm current availability status as older variants may be discontinued. Ensure compatibility with existing PCB footprints for 32-lead thin quad flat pack components before procurement.
Selection Notes
Select this component when a compact 32-pin form factor is required alongside minimal peripheral needs. It is suitable for applications prioritizing low voltage operation over high-speed processing. Consider alternative packages if higher pin counts or different mounting styles are necessary for the target design.
Part Context
This part belongs to the ATtiny28L family, which focuses on cost-effective, low-pin-count solutions. It shares architectural similarities with other tinyAVR devices but offers specific memory and I/O configurations tailored for simple control tasks. The 'V' suffix typically indicates extended voltage ranges or specific speed grades within the product line.
Replacement Considerations
Check for direct cross-references within the ATtiny28L family. Verify pinout compatibility with any substitute parts to ensure seamless integration without PCB redesign.
