ATTINY214-SSN

Overview

The ATtiny214-SSN is an 8-bit AVR microcontroller from the tinyAVR 1-series, housed in a 14-pin SOIC package. It features 4 KB of self-programmable Flash memory, 256 bytes of SRAM, and 128 bytes of EEPROM. The device operates at clock frequencies up to 20 MHz with a supply voltage range of 1.8 V to 5.5 V. Key peripherals include a 10-bit ADC, 8-bit DAC, USART, SPI, TWI, and multiple timer/counters.

Feature Summary

• Integrates Core Independent Peripherals (CIPs) such as TCA, TCB, and TCD timers for CPU offloading.
• Includes an Event System for predictable inter-peripheral signaling without CPU intervention.
• Features Configurable Custom Logic (CCL) with programmable look-up tables for custom logic implementation.
• Supports Single-Pin Unified Program and Debug Interface (UPDI) for programming and debugging.

Applications

• Low-power sensor nodes requiring efficient data acquisition via ADC and event-driven processing.
• Industrial control applications utilizing CIPs for precise timing and motor control tasks.
• Communication interfaces using USART, SPI, or TWI protocols for system connectivity.
• Battery-operated devices leveraging low-voltage operation and configurable sleep modes.

Procurement Notes

Verify the specific speed grade suffix required for your operating voltage and frequency constraints. Confirm that the SSN package variant matches your PCB footprint requirements. Check for any recent Product Change Notifications (PCNs) regarding pinout or electrical characteristics updates before finalizing procurement.

Selection Notes

Select this component if you require 4 KB of Flash memory and advanced peripheral sets like CCL and EVSYS within a compact 14-pin package. Ensure the design supports the UPDI interface for development. Compare against ATtiny212 for lower memory needs or ATtiny414 if higher performance is not critical but similar features are needed.

Part Context

This part belongs to the Microchip tinyAVR 1-series family, designed for cost-sensitive embedded applications. It shares architectural similarities with other members like the ATtiny212 and ATtiny414, differing primarily in memory sizes and I/O counts while maintaining compatible software libraries and development tools.

Replacement Considerations

Direct substitutes within the same series include the ATtiny212 (lower memory) and ATtiny414 (higher memory). Verify pin compatibility and memory size requirements when considering these alternatives. No other cross-family replacements are officially confirmed in the provided documentation.
