ATTINY104F-SSNR

Overview

The ATTINY104F-SSNR is an 8-bit AVR microcontroller featuring a 14-pin SOIC150 package. It includes 1024 bytes of in-system programmable Flash, 32 bytes of SRAM, and 12 general-purpose I/O lines. The device supports a maximum clock frequency of 12 MHz with an operating voltage range of 1.8 V to 5.5 V. Key peripherals include a 10-bit ADC with 8 channels, one USART, one analog comparator, and a 16-bit Timer/Counter. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Non-volatile memory with self-programming capabilities across the full operating voltage range.
• Integrated analog features including a 10-bit ADC and selectable internal voltage references.
• Multiple low-power operational modes including Idle, ADC Noise Reduction, and Power-down.

Applications

• Battery-powered sensor nodes requiring extended data retention and low power consumption.
• Industrial control systems utilizing the industrial temperature range and robust reset circuits.
• Communication interfaces leveraging the on-chip USART module.
• Applications requiring fast start-up times enabled by the 'F' suffix designation.

Procurement Notes

Verify that the specific ordering code matches the required speed grade and package dimensions. Confirm the presence of the fast start-up option associated with the F suffix if rapid initialization is critical. Ensure compatibility with the 14-pin SOIC150 footprint during PCB layout. Check datasheet specifications for humidity sensitivity handling requirements prior to assembly.

Selection Notes

Select this component when 12 GPIO lines are necessary compared to the 6 available in the ATtiny102 variant. The F suffix indicates support for fast start-up time options, suitable for applications requiring immediate system readiness. Verify that the 10-bit ADC resolution meets signal processing requirements. Consider the 14-pin package constraints against available board space.

Part Context

This part belongs to the ATtiny102/ATtiny104 family based on the AVR enhanced RISC architecture. It shares core resources such as Flash size and timer configurations with the ATtiny102 but offers increased I/O capacity through a 14-pin package. The series is designed for cost-sensitive embedded applications needing reliable non-volatile memory and efficient processing.

Replacement Considerations

The ATtiny102-SSNR serves as a pin-compatible alternative only if reduced I/O count (6 pins) is acceptable. Both share identical memory sizes and peripheral sets except for channel availability. Verify package orientation and pin mapping differences before substitution.
