ATTINY412-SSN

Overview

The ATTINY412-SSN is an 8-bit AVR microcontroller from the tinyAVR 1-series family, manufactured by Microchip Technology. It features a high-performance RISC core operating at up to 20 MHz with throughput reaching 20 MIPS. The device integrates 4 KB of system-in-programmable Flash memory, 256 bytes of SRAM, and 128 bytes of EEPROM. Key peripherals include a 10-bit Analog-to-Digital Converter (ADC), two Timer/Counter units, and multiple communication interfaces such as SPI, USART, and I2C. It operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperature ranges in a compact SOIC-14 package.

Feature Summary

• Integrates a high-speed 8-bit AVR RISC core delivering efficient single-cycle instruction execution for low-power applications.
• Includes on-chip non-volatile memory systems comprising Flash, EEPROM, and SRAM for program storage and data retention.
• Features built-in analog conversion capabilities via a 10-bit ADC module for sensor interfacing.
• Supports versatile digital communication protocols including SPI, USART, and I2C for peripheral connectivity.

Applications

• Battery-powered consumer electronics requiring low power consumption
• Industrial control systems needing robust I/O and communication interfaces
• Sensor nodes utilizing integrated ADC for signal acquisition
• Embedded devices requiring reliable non-volatile data storage

Procurement Notes

Verify the specific suffix SSN corresponds to the SOIC-14 package and industrial temperature grade when sourcing. Confirm RoHS compliance status through official Microchip documentation or authorized distributors. Ensure compatibility with existing design tools and programming interfaces supported by the tinyAVR 1-series architecture before procurement.

Selection Notes

Select this component for designs requiring a balance of processing speed and peripheral richness in a small form factor. The 20 MHz operation and extensive I/O count make it suitable for complex logic tasks. Consider the 1.8 V minimum supply voltage for battery-operated projects. Compare against other members of the tinyAVR 1-series if different memory sizes or pin counts are required.

Part Context

This part belongs to the Microchip tinyAVR 1-series, which introduces enhanced features compared to previous generations. The series focuses on improving code density and reducing power consumption while maintaining compatibility with standard AVR development tools. The ATTINY412 variant offers a mid-range memory configuration within this family.

Replacement Considerations

Direct substitutes within the same package and feature set may include other parts from the ATtiny4xx series, such as the ATTINY402 or ATTINY414, provided pinout and memory specifications align with the design requirements. Verify electrical characteristics and software compatibility when migrating between variants.
