ATTINY102-SSFR

Overview

The ATTINY102-SSFR is an 8-bit AVR microcontroller in an 8-pin SOIC package. It features 1024 bytes of Flash, 32 bytes of SRAM, and a 16-bit Timer/Counter. The device supports up to 12 MHz operation at 4.5V to 5.5V and operates within a voltage range of 1.8V to 5.5V. It includes a 10-bit ADC with 5 channels, an Analog Comparator, and a USART interface. Operating temperatures extend from -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 supporting self-programming across the full operating voltage range.
• Integrated peripheral set including a 16-bit Timer/Counter, Analog Comparator, and serial communication module.
• Multiple low-power operational modes designed to optimize system power consumption.

Applications

• Battery-powered sensor nodes requiring extended data retention.
• Industrial control systems utilizing the industrial temperature grade.
• Low-speed serial communication interfaces via the integrated USART.
• Signal conditioning applications using the on-chip Analog Comparator.

Procurement Notes

Verify that the specific suffix SSFR corresponds to the 8-pin SOIC150 package and the +125°C industrial temperature rating as defined in the official ordering information. Confirm the speed grade matches the required operating frequency for the target supply voltage. Ensure compatibility with existing PCB footprints for the specified package dimensions.

Selection Notes

Select this component when a compact 8-pin footprint is required alongside functional safety or industrial temperature requirements. Compare against the ATtiny104 if additional I/O lines are necessary. Evaluate the trade-off between processing speed and power consumption based on the available internal oscillators and sleep modes.

Part Context

This part belongs to the ATtiny102/ATtiny104 family, which utilizes Atmel's high-density Non-Volatile Memory technology. The series is characterized by its enhanced RISC core and focus on low-power performance. The device provides a balance of processing capability and energy efficiency suitable for resource-constrained embedded environments.

Replacement Considerations

The ATtiny102F-SSFR serves as a direct substitute offering the fast start-up time option. Other variants within the ATtiny102 family may be considered if different package types or temperature grades are acceptable for the application design.
