ATTINY25V-10SNR

Overview

The ATTINY25V-10SNR is an 8-bit AVR microcontroller featuring 2KB of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates at speeds up to 10MHz within a supply voltage range of 1.8V to 5.5V. The device includes four single-ended 10-bit ADC channels, six programmable I/O lines, and a Universal Serial Interface (USI). It supports industrial temperature ranges and utilizes surface-mount 8-SOIC packaging.

Feature Summary

• AVR enhanced RISC architecture with single-clock-cycle execution
• In-system programmable non-volatile memory for program and data storage
• Integrated analog-to-digital converter with differential channel support
• Programmable watchdog timer and multiple power-saving operational modes

Applications

• Industrial control systems requiring low-power embedded processing
• Battery-operated devices utilizing picoPower technology
• Sensor interfaces incorporating analog signal conditioning
• General-purpose embedded logic controllers

Procurement Notes

Verify the specific speed grade suffix '10' corresponds to the required 10MHz frequency rating at the target operating voltage. Confirm the 'V' designation indicates the extended 1.8V minimum supply capability. Ensure the 'SNR' package code matches the required 8-SOIC form factor with tape-and-reel delivery specifications for automated assembly processes.

Selection Notes

Select this component when a balance of moderate program memory capacity and low-voltage operation is necessary. The V-series variant is appropriate for designs requiring functionality down to 1.8V. Consider the USI interface if standard SPI or TWI peripherals are insufficient for the specific communication protocol requirements of the application.

Part Context

This device belongs to the ATtiny25/45/85 family of 8-bit microcontrollers manufactured by Microchip Technology. It shares architectural similarities with the ATtiny45 and ATtiny85, differing primarily in memory sizes. The V-series variants specifically extend the low-voltage operating range compared to standard ATtiny models.
