Overview
The ATTINY406-SNR is an 8-bit AVR microcontroller from Microchip Technology, featuring a 12 MHz RISC CPU core. It integrates 8 KB of in-system programmable Flash memory, 512 bytes of SRAM, and 128 KB of EEPROM. The device includes a 12-channel 10-bit ADC, two 16-bit timers (TCA/TCC), and a watchdog timer. Operating within a voltage range of 1.8 V to 5.5 V, it supports up to 18 I/O lines and utilizes the UPDI interface for programming and debugging.
Feature Summary
- Integrates a high-performance 8-bit AVR RISC processor with hardware multiplication capabilities.
- Features a flexible event system and configurable custom logic for low-latency peripheral control.
- Includes precise analog subsystems with a 12-channel 10-bit ADC and dual comparators.
- Supports ultra-low power operation through multiple sleep modes including Idle, Standby, and Power-down.
Applications
- Battery-powered sensor nodes requiring extended operational life
- Industrial control systems utilizing precise analog signal acquisition
- Smart home automation devices with multiple I/O requirements
Procurement Notes
Verify the specific suffix 'SNR' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding the 20-pin SOIC or TSSOP form factor. Confirm that the 1.8V to 5.5V operating range aligns with the target application's power supply specifications before finalizing procurement.
Selection Notes
Select this component when applications require substantial non-volatile storage alongside high-resolution analog input channels. The combination of 8 KB Flash and 128 KB EEPROM distinguishes it from smaller variants in the TinyAVR series. Consider the 12 MHz maximum clock speed and available I/O count relative to system complexity and timing requirements.
Part Context
This part belongs to the TinyAVR 1-series family, designed for cost-sensitive embedded applications. It shares architectural similarities with other members like the ATtiny406 but offers increased memory capacity. The series emphasizes energy efficiency and simplified development through the unified serial programming interface.
Replacement Considerations
Direct substitutes include other parts within the TinyAVR 1-series family with equivalent pin counts and memory sizes. Verify functional compatibility regarding peripheral availability and electrical characteristics before substitution.
