ATTINY861V-10MU

Overview

The ATTINY861V-10MU is an 8-bit AVR microcontroller featuring 8KB of in-system programmable Flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at a maximum frequency of 10MHz with a supply voltage range of 1.8V to 5.5V. The device includes 16 I/O lines, an 11-channel 10-bit ADC, and a USI interface. It is housed in a 32-pin VQFN package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates an 8-bit AVR RISC core for efficient instruction execution.
• Includes an internal oscillator for clock generation without external components.
• Features built-in power-on reset and brown-out detection circuits.

Applications

• Battery-powered portable devices requiring low voltage operation
• Simple sensor interfaces utilizing the analog-to-digital converter
• Basic communication systems using the USI peripheral

Procurement Notes

Verify the specific suffix 'MU' against the manufacturer's current datasheet to confirm the exact package dimensions and marking details. Ensure the ordering code matches the required tape-and-reel or cut-tape format. Confirm that the 'V' designation aligns with the intended industrial temperature grade requirements for your specific application environment.

Selection Notes

Select this component when an 8-bit architecture suffices for control tasks. The 8KB Flash capacity accommodates moderate firmware sizes. The 10MHz speed is suitable for non-real-time applications. Consider alternative ATtiny models if higher pin counts or additional hardware peripherals like hardware UART are necessary.

Part Context

This part belongs to the Microchip ATtiny family, specifically the ATtiny861 variant. It shares architectural similarities with the ATtiny261 and ATtiny461 but offers increased program memory. The series is designed for cost-sensitive embedded applications where power efficiency and compact packaging are primary design constraints.

Replacement Considerations

Direct substitutes include the ATTINY861A-SSU or ATTINY861V-10PU depending on the required package type. Verify pin compatibility and memory specifications before swapping. Cross-reference the latest datasheets to ensure functional equivalence regarding peripheral availability and electrical characteristics.
