ATTINY861V-10SU

Overview

The ATTINY861V-10SU 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 clock frequency of 10 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes 16 programmable I/O lines, an 11-channel 10-bit ADC, and a Universal Serial Interface. It is housed in a 20-pin SOIC package.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle for high throughput efficiency.
• Integrated non-volatile memories including Flash, EEPROM, and SRAM with data retention capabilities.
• Comprehensive peripheral set featuring a 10-bit ADC, analog comparator, and timer/counters with PWM outputs.

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications utilizing the industrial temperature range
• Sensor interfaces leveraging the multi-channel ADC and analog comparator

Procurement Notes

Verify the specific suffix 'SU' corresponds to the 20-pin SOIC package variant when sourcing. Confirm the 'V' designation indicates the 1.8V operating capability if required by the design. Ensure compatibility with existing SPI programming interfaces for in-system programming.

Selection Notes

Select this component for designs needing 8K program memory within a compact 20-pin form factor. The 1.8V minimum voltage supports battery operation better than standard voltage variants. Consider the SOIC package for surface mount assembly requirements.

Part Context
