ATTINY406-SN

Overview

The ATTINY406-SN is an 8-bit AVR microcontroller featuring a high-performance RISC CPU operating at up to 20 MHz. It integrates 8 KB of in-system programmable Flash, 512 bytes of SRAM, and 256 bytes of EEPROM. The device supports a supply voltage range of 1.8 V to 5.5 V and operates within a temperature range of -40°C to +85°C. Key peripherals include a 12-channel 10-bit ADC, two 16-bit timers, and a configurable custom logic block. Communication is facilitated via SPI, USART, and I2C interfaces, with programming handled through the single-pin UPDI interface.

Feature Summary

• Integrates a hardware multiplier for efficient arithmetic operations within the AVR core architecture.
• Features a low-power design with multiple sleep modes including Idle, Standby, and Power-Down.
• Includes an event system allowing peripheral-to-peripheral communication without CPU intervention.
• Supports precise analog measurements through a multi-channel ADC with selectable reference voltages.

Applications

• Battery-powered sensor nodes requiring low power consumption
• Industrial control systems utilizing analog signal processing
• Smart home automation devices with limited pin counts
• Consumer electronics requiring reliable embedded control

Procurement Notes

Verify the complete part number against official Microchip documentation to ensure correct package type and temperature grade. Confirm that the specific suffix matches your board layout requirements. Cross-reference datasheet revisions to validate electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when an 8-bit AVR solution with integrated analog capabilities is required. Ensure the 20 MHz clock speed meets real-time processing needs. Verify that the 8 KB Flash capacity accommodates firmware growth. Check that the 24-pin SOIC package fits the available PCB space.

Part Context

This device belongs to the TinyAVR™ 0-series family, designed for cost-sensitive applications. It shares architectural similarities with other members like the ATTINY406 but differs in memory size and pin count. The series emphasizes flexibility through its event system and low-power features for embedded control tasks.

Replacement Considerations

Check for direct substitutes within the TinyAVR 0-series such as ATTINY206 or ATTINY806 based on memory requirements. Verify pin compatibility if replacing existing designs. Consult official cross-reference guides for package and electrical equivalence.
