ATTINY406-SF

Overview

The ATTINY406-SF is an 8-bit AVR microcontroller from Microchip Technology, housed in a 14-lead SOIC surface-mount package. It features 6KB of Flash memory for program storage and 256 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. Key peripherals include a 10-bit Analog-to-Digital Converter (ADC) with up to 8 channels, two Timer/Counter units, and standard communication interfaces such as SPI, I2C, and USART.

Feature Summary

• Integrated 10-bit ADC with multiple input channels for analog signal acquisition
• Dual Timer/Counter modules providing flexible timing and counting capabilities
• Supports serial communication protocols including SPI, I2C, and USART

Applications

• Battery-powered portable devices requiring low voltage operation
• Sensor interface nodes utilizing the integrated ADC
• Simple control loops managed by timer functions
• Serial data logging applications using USART or SPI

Procurement Notes

Verify the specific suffix 'SF' against the official Microchip datasheet to confirm package type and temperature grade. Ensure the ordering part number matches the required pinout and electrical specifications for your design. Cross-reference with the latest product change notices to avoid obsolete variants.

Selection Notes

Select this component when a balance of moderate code space and peripheral richness is needed in a small footprint. Compare against the ATTINY404 and ATTINY408 if different memory sizes or I/O counts are required. Consider the operating voltage range and available timers relative to system complexity.

Part Context

This part belongs to the ATtiny40x family, which shares architectural similarities with other modern AVR devices. It offers enhanced features compared to legacy ATtiny series while maintaining compatibility with existing development tools. The family focuses on cost-effective solutions for embedded control tasks.

Replacement Considerations

Direct substitutes within the same package may include ATTINY404-SF or ATTINY408-SF, depending on memory requirements. Verify pin compatibility and peripheral availability before substitution.
