ATTINY85V-10PI

Overview

The ATTINY85V-10PI 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 frequencies up to 10 MHz across a supply voltage range of 1.8V to 5.5V. The device includes six programmable I/O lines, a 10-bit ADC with four single-ended channels, a Universal Serial Interface (USI), and an on-chip analog comparator. It supports industrial temperature ranges from -40°C to +85°C and utilizes an 8-pin PDIP package.

Feature Summary

• Advanced RISC architecture achieving near 1 MIPS per MHz throughput with most instructions executing in a single clock cycle.
• Integrated non-volatile memory including ISP Flash, EEPROM, and internal SRAM with programming lock for data security.
• Comprehensive peripheral set comprising an 8-bit Timer/Counter, high-speed PWM outputs, USI, and a 10-bit ADC.
• Low power consumption capabilities with multiple selectable sleep modes including Idle, Power-down, and ADC Noise Reduction.

Applications

• Battery-powered embedded systems requiring extended operational life
• Simple sensor interfaces utilizing the integrated ADC and analog comparator
• Basic communication protocols implemented via the Universal Serial Interface
• Cost-sensitive consumer electronics within industrial temperature environments

Procurement Notes

Verify that the specific part number matches the required speed grade and voltage range specifications. Confirm the package type corresponds to the design requirements. Ensure compliance with relevant environmental directives if applicable. Cross-reference the manufacturer's latest documentation for any updates to ordering codes or pin configurations before finalizing procurement decisions.

Selection Notes

Select this component when an 8-bit AVR core with substantial program memory is needed for low-power applications. The V suffix indicates operation down to 1.8V, suitable for battery management. Consider the PDIP package for prototyping or through-hole manufacturing constraints. Evaluate the available I/O lines and peripheral count against system complexity to ensure adequate resource allocation.

Part Context

This device belongs to the ATtiny25/45/85 family of microcontrollers manufactured by Microchip Technology. It shares the same core architecture and peripheral features as other members of the series, differentiated primarily by flash memory capacity. The ATTINY85 variant provides the highest storage capacity within this specific group, supporting more complex firmware implementations.

Replacement Considerations

Compatible substitutes include ATTINY85-10PU and ATTINY85V-10SU. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement part meets the same voltage and frequency requirements.
