ATTINY406-MNR

Overview

The ATTINY406-MNR is an 8-bit AVR microcontroller featuring 4KB of in-system programmable Flash memory, 256 bytes of EEPROM, and 512 bytes of SRAM. It operates at a maximum clock frequency of 20MHz with a supply voltage range of 1.8V to 5.5V. The device includes 14 I/O lines, a 10-bit ADC, and multiple communication interfaces including SPI, USART, and TWI. It is housed in a 20-SSOP package and supports industrial temperature ranges.

Feature Summary

• Integrated 10-bit analog-to-digital converter for signal processing
• Supports serial programming via SPI, USART, and TWI interfaces
• Features internal oscillator and watchdog timer for system stability

Applications

• Battery-powered sensor nodes
• Industrial control systems
• Consumer electronics peripherals

Procurement Notes

Verify the specific suffix 'MNR' against the official Microchip datasheet to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements before finalizing procurement.

Selection Notes

Select this component when a balance of moderate program memory and robust analog capabilities is required. The 20MHz speed and wide voltage range make it suitable for cost-sensitive applications needing reliable data acquisition without complex external components.

Part Context

This part belongs to the ATtiny406 series within the Microchip AVR family. It shares architectural similarities with other members like the ATtiny206 and ATtiny806, differing primarily in memory sizes while maintaining consistent pinouts and peripheral sets for easy scalability.

Replacement Considerations

Check for direct pin-compatible alternatives such as the ATtiny206 or ATtiny806 depending on memory needs. Verify that any substitute maintains the same SSOP-20 package and electrical characteristics.
