ATTINY204-SSN

Overview

The ATtiny204-SSN is an 8-bit AVR microcontroller from Microchip Technology, housed in a 14-pin SOIC package. It features 2 KB of Flash memory, 128 bytes of SRAM, and 64 bytes of EEPROM. The device operates at clock speeds up to 20 MHz with a supply voltage range of 1.8 V to 5.5 V. Key specifications include a 10-bit ADC, three I/O lines available for general use, and support for industrial temperature ranges.

Feature Summary

• Integrates Core Independent Peripherals (CIP) such as the Event System and SleepWalking to offload tasks from the CPU, enhancing energy efficiency.
• Features picoPower technology with multiple sleep modes including Idle, Standby, and Power-down to minimize active and standby power consumption.
• Includes advanced analog peripherals like a 10-bit ADC with selectable internal voltage references and an Analog Comparator for precise signal processing.

Applications

• Battery-powered sensor nodes requiring low standby current
• Industrial control systems utilizing core-independent peripheral automation
• Smart home devices needing efficient event-driven processing

Procurement Notes

Verify the specific suffix 'SSN' corresponds to the 14-pin SOIC package and industrial temperature grade (-40°C to +105°C). Confirm that the ordering code matches the exact memory configuration of 2 KB Flash. Ensure compatibility with the Unified Program and Debug Interface (UPDI) for programming requirements.

Selection Notes

Select this component when a balance of moderate program memory and high performance is required within a compact 14-pin footprint. It is suitable for applications needing hardware multipliers and flexible I/O options without the complexity of larger pin-count packages. Consider the availability of core-independent peripherals for power-sensitive designs.

Part Context

This part belongs to the tinyAVR 0-Series family, which emphasizes low power and small form factors. It shares architectural similarities with other members like the ATtiny404 but offers reduced memory resources. The series utilizes the UPDI interface, simplifying development compared to legacy ISP or JTAG interfaces found in older AVR families.

Replacement Considerations

Direct replacements within the same package and pinout include the ATtiny204 variants with different temperature grades or suffixes. Cross-family migration to PIC10/12/16 series requires significant schematic and firmware redesign due to architectural differences.
