ATTINY104-SSFR

Overview

The ATTINY104-SSFR is an 8-bit AVR microcontroller in a 14-pin SOIC package. It features 1024 bytes of Flash, 32 bytes of SRAM, and 12 programmable I/O lines. The device operates at up to 12 MHz with a supply voltage range of 1.8V to 5.5V. Key peripherals include a 16-bit Timer/Counter, a 10-bit ADC with 8 channels, an Analog Comparator, and a USART interface.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Integrated non-volatile memory with self-programming capabilities across the full operating voltage range.
• Multiple low-power operational modes including Idle, ADC Noise Reduction, and Power-down to optimize energy consumption.
• On-chip calibration oscillator providing accurate internal timing without external components.

Applications

• Low-power embedded control systems
• Battery-operated consumer devices
• Simple serial communication interfaces
• Analog signal acquisition applications

Procurement Notes

Verify the specific speed grade suffix matches the required operating frequency for the target voltage range. Confirm the SSFR suffix indicates the correct tape and reel packaging format for automated assembly processes. Ensure the industrial temperature rating aligns with environmental requirements.

Selection Notes

Select this component when a compact 14-pin solution is needed with moderate I/O count and analog capabilities. Compare against the ATtiny102 if fewer pins are sufficient. Consider the 12MHz maximum speed limit and 1024-byte memory constraint for code complexity.

Part Context

This part belongs to the ATtiny102/ATtiny104 family, designed for cost-sensitive applications requiring efficient processing. It utilizes Atmel's high-density Non-Volatile Memory technology. The series emphasizes power optimization while maintaining performance suitable for basic control tasks.

Replacement Considerations

The ATtiny102-SSFR is a pin-compatible alternative within the same family but offers only 6 general purpose I/O lines instead of 12. Verify that the reduced pin count meets the design requirements before substituting.
