Overview
The ATTINY406-MFR is an 8-bit AVR microcontroller from Microchip Technology, housed in a 20-lead MLF package. It features 8KB of In-System Programmable Flash memory and 512 bytes of SRAM. The device operates with a maximum clock frequency of 20 MHz and supports a supply voltage range of 1.8V to 5.5V. It includes integrated peripherals such as a 10-bit ADC, multiple timer/counters, and communication interfaces including SPI, USART, and I2C.
Feature Summary
- Integrates high-density non-volatile Flash memory for code storage.
- Provides versatile analog-to-digital conversion capabilities.
- Supports standard serial communication protocols for system connectivity.
Applications
- General-purpose embedded control systems
- Sensor interface modules
- Low-power consumer electronics
Procurement Notes
Verify the specific suffix 'MFR' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the MLF package. Confirm that the selected variant meets all required electrical specifications for the target application environment.
Selection Notes
Select this component when an 8-bit AVR architecture with moderate program memory is required. Consider the 20-pin form factor for space-constrained designs. Evaluate the 20 MHz performance against processing needs and verify power consumption requirements within the specified voltage range.
Part Context
This part belongs to the ATtiny406 family, which offers enhanced peripheral sets compared to smaller variants. It shares architectural similarities with other AVR devices but provides a specific balance of memory and I/O count suitable for mid-range applications requiring reliable 8-bit processing.
Replacement Considerations
Check for direct pin-compatible alternatives within the ATtiny series. Verify if higher-memory variants like the ATtiny407 serve as functional upgrades. Cross-reference pinouts and register maps before substituting with other manufacturers' 8-bit MCUs.
