ATTINY102-MFR

Overview

The ATtiny102-MFR is an 8-bit AVR microcontroller featuring a high-performance RISC architecture with up to 1 MIPS throughput per MHz. It integrates 1024 bytes of in-system programmable Flash, 32 bytes of SRAM, and supports operation from 1.8V to 5.5V. The device includes a 16-bit Timer/Counter, a 10-bit ADC with five channels, a USART, and an Analog Comparator. It operates within a temperature range of -40°C to +125°C and utilizes an 8-pin SOIC150 package.

Procurement Notes

Verify that the specific ordering suffix matches the required speed grade and temperature range. Confirm the package type corresponds to the design requirements. Ensure compatibility with existing development tools and programming interfaces before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring minimal I/O lines and basic analog capabilities. Consider the limited SRAM size when evaluating code complexity. Verify that the available timer channels and ADC inputs meet the system's functional requirements without needing external peripherals.

Part Context

This part belongs to the ATtiny102/ATtiny104 family of 8-bit AVR microcontrollers. It shares architectural similarities with other devices in the series but differs in pin count and peripheral availability. The MFR suffix indicates the manufacturer designation for this specific variant.

Replacement Considerations

Direct substitutes include other ATtiny102 variants with different packaging or speed grades. Cross-referencing pinouts and memory sizes is essential when considering alternative microcontrollers from the same or different families.

FAQ

What is the maximum operating frequency at 1.8V?
