ATTINY414-SSNR

Overview

The ATTINY414-SSNR is an 8-bit AVR microcontroller from Microchip Technology, featuring a 20 MHz maximum clock frequency and 4 KB of Flash program memory. It includes 256 bytes of SRAM and operates within a voltage range of 1.8 V to 5.5 V. The device provides 12 I/O pins and integrates a 10-bit ADC with 10 channels. Packaged in SOIC-14, it supports industrial temperature ranges up to +105°C and utilizes tape-and-reel packaging for surface-mount assembly.

Feature Summary

• Integrates high-performance 8-bit AVR RISC core with single-cycle instruction execution
• Includes non-volatile memory systems comprising Flash, EEPROM, and SRAM
• Features analog-to-digital conversion capabilities with multiple input channels
• Supports standard serial communication interfaces including SPI, I2C, and USART

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control modules operating in extended temperature environments
• Sensor interface nodes utilizing the integrated ADC functionality
• General-purpose logic control applications via available I/O ports

Procurement Notes

Verify the specific suffix SSNR confirms tape-and-reel packaging rather than tube format when reviewing official datasheets or distributor specifications. Confirm the industrial temperature grade (+105°C) matches application requirements. Ensure the SOIC-14 package dimensions align with PCB footprint designs. Cross-reference the exact part number against manufacturer documentation to validate pinout and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component for applications needing moderate code storage with efficient processing speed. The 4 KB Flash size suits simple firmware implementations. Consider the 12 I/O count for peripheral connectivity needs. Evaluate the 1.8 V minimum supply voltage for compatibility with low-power battery sources. Compare against other ATtiny variants if higher memory or additional timers are required.

Part Context

This microcontroller belongs to the ATtiny family, known for compact size and efficiency. It shares architectural similarities with other AVR devices but offers specific memory and I/O configurations tailored for cost-sensitive applications. The SOIC-14 package provides a balance between pin count and physical footprint, suitable for space-constrained designs.

Replacement Considerations

The ATTINY414-SSN serves as a direct functional substitute differing only in packaging format (tube versus reel). Other ATtiny series members may offer compatible pinouts but require verification of memory sizes and peripheral sets.
