ATTINY102F-M7R

Overview

The ATTINY102F-M7R is an 8-bit AVR microcontroller featuring a high-performance RISC architecture with up to 1 MIPS per MHz throughput. It integrates 1024 bytes of in-system programmable Flash, 32 bytes of SRAM, and operates within a voltage range of 1.8V to 5.5V. The device supports speeds up to 12MHz at the upper voltage limit and includes a 10-bit ADC with five channels, one USART, and a 16-bit Timer/Counter. It utilizes an 8-pad UDFN package and is rated for industrial temperatures from -40°C to +105°C.

Feature Summary

• Advanced RISC core executing most instructions in a single clock cycle
• In-system programmable Flash memory with read-while-write capability
• Integrated analog comparator and 10-bit ADC with selectable internal references
• Programmable Watchdog Timer with separate on-chip oscillator

Applications

• Low-power consumer electronics requiring minimal I/O
• Battery-operated devices utilizing multiple power-saving modes
• Simple serial communication interfaces via USART
• Applications necessitating fast start-up times

Procurement Notes

Verify that the specific suffix M7R corresponds to the 8-pad UDFN package and the -40°C to +105°C industrial temperature range as documented in the ordering information table. Confirm the 'F' designation indicates the inclusion of the fast start-up time option. Ensure compatibility with 8-pin SOIC or other packages if physical footprint requirements differ from the specified UDFN form factor.

Selection Notes

Select this component when a compact 8-pin solution is required alongside basic analog and digital peripherals. The ATtiny102 variant provides six programmable I/O lines suitable for constrained designs. Consider the fast start-up feature if system latency constraints are critical. Verify that the 1024-byte Flash and 32-byte SRAM capacities meet application code and data storage needs without requiring external memory expansion.

Part Context

This part belongs to the ATtiny102/ATtiny104 family manufactured by Microchip Technology (formerly Atmel). It shares the same core architecture and peripheral set as the standard ATtiny102 but differs in packaging and speed grade specifications. The F-suffix variants specifically offer enhanced start-up performance compared to non-F counterparts within the same series.

Replacement Considerations

The ATtiny102-M7R serves as a direct functional substitute for the ATTINY102F-M7R, differing only in branding history. For package variations, the ATtiny102-SSNR offers identical electrical characteristics in an 8-pin SOIC150 format.
