Overview
The ATTINY28V-1AUR 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 minimum supply voltage of 1.8 V and a maximum of 5.5 V. The device supports a maximum clock frequency of 1.2 MHz and includes 11 general-purpose I/O lines. It is housed in a 32-pin MLF package designed for surface mount installation. The component functions within a temperature range of -40°C to +85°C and utilizes an 8-bit data bus width.
Feature Summary
- Integrates non-volatile Flash program memory for code storage
- Supports low-voltage operation starting at 1.8 V
- Provides multiple configurable digital input/output pins
- Compatible with standard surface mount assembly processes
Applications
- Low-power embedded control systems
- Battery-operated portable devices
- Simple sensor interface circuits
- Basic logic control applications
Procurement Notes
Verify the manufacturer designation carefully, as Atmel was acquired by Microchip Technology. Confirm the specific suffix indicates the correct package type and speed grade. Check current availability status as older variants may be discontinued or subject to last-time buy notices. Ensure compatibility with existing PCB footprints for the 32-pin MLF package before ordering.
Selection Notes
Select this component when a small form factor MCU with integrated Flash is required for low-voltage designs. The 1.8 V minimum operating voltage makes it suitable for battery-powered applications. Consider the 11 available I/O lines against project pin requirements. Verify that the 1.2 MHz processing speed meets the timing constraints of the intended application logic.
Part Context
This part belongs to the ATtiny28L family of 8-bit AVR microcontrollers. These devices are designed for cost-sensitive and space-constrained applications requiring moderate performance. The family typically offers a balance of processing capability and peripheral integration within compact packages. The specific model variant defines the package style and operational speed limits.
Replacement Considerations
Consult official Microchip documentation for direct cross-references. Alternative parts within the same ATtiny28L series may offer different package options or speed grades. Verify pinout compatibility if substituting with other 8-bit AVR MCUs.
