ATTINY414-SSF

Overview

The ATTINY414-SSF is an 8-bit AVR microcontroller from Microchip Technology, housed in a 14-SOIC package. It features 4 kB of Flash program memory, 256 B of SRAM, and 128 B 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, an 8-bit DAC, and three timers/counters. Communication interfaces include I2C, SPI, and USART. The component is rated for industrial temperatures from -40°C to +125°C.

Feature Summary

• Integrates high-performance 8-bit AVR architecture with non-volatile memory systems including Flash, EEPROM, and SRAM.
• Provides versatile analog capabilities through a 10-bit ADC and an 8-bit DAC for signal processing applications.
• Supports multiple serial communication protocols including I2C, SPI, and USART for system connectivity.

Applications

• Industrial control systems requiring robust microcontroller performance
• Sensor interface modules utilizing analog-to-digital conversion
• Embedded devices needing serial communication via SPI or USART

Procurement Notes

Verify the specific suffix SSF corresponds to the tube packaging format when ordering. Confirm that the industrial temperature grade (-40°C to +125°C) meets the operational requirements of the target environment. Ensure compatibility with the 1.8 V to 5.5 V supply voltage range for the intended power design.

Selection Notes

Select this component for applications requiring a balance of processing speed and low power consumption within the tinyAVR family. Consider the 14-pin SOIC package constraints for PCB layout. Evaluate the 4 kB Flash size against firmware complexity requirements before finalizing the design choice.

Part Context

This part belongs to the ATtiny414 series, which is part of Microchip's tinyAVR portfolio. These microcontrollers are designed for cost-sensitive and space-constrained embedded applications. The series emphasizes functional safety and ease of use with integrated peripherals.

Replacement Considerations

Check for ATTINY414-SSFR if reel packaging is required instead of tubes. Verify ATTINY414-SSN for alternative industrial grade options if available.
