ATTINY85V-10SI

Overview

The ATTINY85V-10SI is an 8-bit AVR microcontroller featuring 8K bytes of In-System Programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at a maximum frequency of 10 MHz with a supply voltage range of 1.8V to 5.5V. The device includes six programmable I/O lines, a 4-channel 10-bit ADC, two PWM channels, and a Universal Serial Interface.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• Non-volatile memory with high endurance for program and data storage
• Integrated peripheral features including timers, ADC, and analog comparator
• Supports low power consumption modes such as Idle and Power-down

Applications

• Low power embedded control systems
• Battery operated devices requiring extended operational life
• Simple sensor interfaces utilizing the integrated ADC
• Basic communication applications via SPI or USI protocols

Procurement Notes

Verify the specific ordering code matches the required speed grade and package type. Confirm that the 'V' suffix indicates the lower voltage operating range suitable for your supply rails. Ensure the 'SI' designation corresponds to the SOIC-8 package format required for your PCB layout. Cross-reference the manufacturer's latest documentation for any updates on pin compatibility or electrical characteristics.

Selection Notes

Select this component when 8KB of program memory is sufficient for the application logic. The 10MHz speed grade provides adequate processing power for simple control tasks while maintaining low power consumption. Consider the 1.8V minimum operating voltage if designing for battery-powered applications where energy efficiency is critical. Verify that the SOIC-8 package fits within the available board space constraints.

Part Context

This part belongs to the ATtiny family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. It shares core functionalities with other members like the ATtiny25 and ATtiny45, differing primarily in memory capacities. The V suffix denotes the low-voltage variant capable of operation down to 1.8V, expanding its utility in portable electronics compared to standard voltage versions.
