ATTINY414-SSN

Overview

The ATTINY414-SSN is an 8-bit AVR microcontroller featuring a 20 MHz maximum clock frequency and 4 KB of in-system programmable Flash 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, a 10-bit ADC, and supports industrial temperature ranges from -40°C to +105°C. Packaged in a SOIC-14 format, it integrates essential peripherals for low-power embedded applications.

Feature Summary

• High-performance 8-bit AVR architecture with advanced RISC capabilities
• Low power consumption across multiple operating modes
• Integrated non-volatile memory with high endurance ratings
• On-chip analog-to-digital conversion and timer/counters

Applications

• Battery-powered sensor nodes
• Industrial control systems requiring wide temperature operation
• Consumer electronics with space-constrained designs
• Smart home automation devices

Procurement Notes

Verify the specific suffix 'SSN' confirms the SOIC-14 package and industrial temperature grade (-40°C to +105°C). Ensure compatibility with existing PCB footprints and reflow profiles for SOIC packages. Confirm RoHS compliance status through official Microchip documentation prior to integration into regulated products.

Selection Notes

Select this component when 4 KB of program memory and 12 general-purpose I/O lines are sufficient for the application logic. Consider the 20 MHz speed limit and 1.8 V minimum supply voltage constraints. Evaluate if the integrated 10-bit ADC resolution meets signal processing requirements compared to higher-resolution alternatives in the same family.

Part Context

This part belongs to the ATtiny4/5/9 series of 8-bit AVR microcontrollers designed for cost-sensitive and power-efficient applications. It shares architectural similarities with other members like the ATtiny402 but offers increased I/O count and memory capacity suitable for slightly more complex embedded tasks while maintaining a compact footprint.

Replacement Considerations

Direct pin-compatible substitutes within the same package include other variants from the ATtiny4/5/9 series such as the ATtiny402 or ATtiny412, provided their memory sizes and peripheral sets align with design requirements. Verify electrical specifications match before substitution.
