ATTINY814-SSNR

Overview

The ATTINY814-SSNR is an 8-bit AVR microcontroller featuring 8 kB of Flash memory, 512 bytes of SRAM, and 128 bytes of EEPROM. It operates at a maximum clock frequency of 20 MHz within a 14-pin SOIC package. The device supports a supply voltage range of 1.8 V to 5.5 V and functions across temperatures from -40°C to +105°C. Key peripherals include a 10-bit ADC with 10 channels, an 8-bit DAC, USART, SPI, and TWI interfaces.

Feature Summary

Integrates core-independent peripherals including a Peripheral Touch Controller for capacitive touch sensing
Features a flexible low-power architecture with Event System and SleepWalking capabilities
Includes advanced analog features such as a 10-bit ADC and configurable custom logic

Applications

Capacitive touch interface implementations
Low-power sensor nodes
Industrial control applications

Procurement Notes

Verify the specific suffix 'SSNR' corresponds to the SOIC-14 tape and reel packaging configuration. Confirm that the operating temperature grade matches the industrial requirement of -40°C to +105°C. Ensure compatibility with the Single Pin Unified Program Debug Interface (UPDI) for programming and debugging workflows.

Selection Notes

Select this component when 8 kB of program memory and 12 I/O lines are required in a compact 14-pin form factor. It is suitable for designs needing integrated capacitive touch sensing via the PTC peripheral. Consider the 1.8 V to 5.5 V operating range for versatile power supply integration.

Part Context

This part belongs to the ATtiny214/414/814 series within Microchip's tinyAVR 1-Series family. These microcontrollers utilize high-performance low-power RISC architecture. The series emphasizes energy efficiency through picoPower technology and includes core-independent peripherals to offload the CPU.
