ATTINY412-SSF

Overview

The ATTINY412-SSF is an 8-bit AVR microcontroller from Microchip Technology, housed in a 14-pin SOIC package. It features 4 kB of Flash program memory, 256 bytes of SRAM, and 128 bytes of EEPROM. The device supports a maximum clock frequency of 20 MHz and operates within a supply voltage range of 1.8 V to 5.5 V. It includes a 10-bit ADC with 10 channels, three timers/counters, and communication interfaces such as I2C, SPI, and USART. The component is rated for an industrial temperature range of -40°C to +125°C.

Feature Summary

• Integrates a 10-bit analog-to-digital converter with multiple input channels for signal acquisition.
• Supports high-temperature operation up to 125°C for industrial environments.
• Includes versatile communication peripherals including I2C, SPI, and USART.
• Features non-volatile data storage via integrated EEPROM.

Applications

• Industrial control systems requiring robust temperature performance
• Sensor interface modules utilizing ADC capabilities
• Embedded applications needing serial communication protocols

Procurement Notes

Verify the specific suffix 'SSF' against official Microchip documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the procurement source provides valid RoHS compliance certificates. Confirm that the part number matches the current active status in the manufacturer's catalog, as availability may vary by region.

Selection Notes

Select this component when a balance of moderate code space (4 kB) and peripheral richness is required in a compact SOIC-14 form factor. It is suitable for designs needing multiple ADC channels and standard serial interfaces without the complexity of larger MCU families. Consider the 125°C rating if the application environment exceeds standard commercial limits.

Part Context

This device belongs to the ATtinyAVR-1 Series, which focuses on low power consumption and high performance per watt. The series utilizes advanced RISC architecture for efficient code execution. The SOIC-14 package offers a compact solution for space-constrained PCB layouts while maintaining accessible pinouts for development and integration.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Potential alternatives within the same family include ATTINY414 or ATTINY416, depending on specific memory or pin count requirements. Verify pin compatibility and software register mapping before substitution.
