ATTINY102F-M8R

Overview

The ATtiny102F-M8R is an 8-bit AVR microcontroller featuring a 12 MHz throughput, 1024 Bytes of Flash memory, and 32 Bytes of SRAM. It operates within a 1.8 V to 5.5 V supply range across an industrial temperature span of -40°C to +125°C. The device includes a 10-bit ADC with five channels, one USART, and six programmable I/O lines housed in an 8-pad UDFN package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high efficiency
• In-system programmable non-volatile Flash memory supporting self-programming across the full operating voltage range
• Integrated analog peripherals including a 10-bit ADC and an on-chip analog comparator

Applications

• Industrial sensor nodes requiring extended temperature operation
• Battery-powered devices utilizing low-power idle and power-down modes
• Systems requiring serial communication via the integrated USART module

Procurement Notes

Verify that the specific ordering code matches the required speed grade and package type. Confirm the industrial temperature rating aligns with environmental specifications. Ensure the UDFN package dimensions meet board layout constraints before finalizing procurement.

Selection Notes

Select this model when an 8-pin footprint is necessary alongside industrial temperature capabilities. The F suffix indicates fast start-up time options. Compare against standard variants if lower temperature ranges or different packages are acceptable for the design.

Part Context

This component belongs to the ATtiny102/ATtiny104 family based on the AVR enhanced RISC architecture. It shares core resources with the ATtiny104 but offers fewer I/O lines due to its 8-pin configuration. The series supports both external programming and self-programming capabilities.

Replacement Considerations

The ATtiny102-M8R serves as a direct substitute lacking the fast start-up feature. Cross-family replacements require verification of pin compatibility and instruction set differences.
