ATTINY25V-10SHR

Overview

The ATTINY25V-10SHR is an 8-bit AVR microcontroller manufactured by Microchip Technology. It features a high-performance, low-power architecture with 2 KB of In-System Programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of internal SRAM. The device operates at a maximum clock frequency of 10 MHz within a supply voltage range of 1.8 V to 5.5 V. It includes six programmable I/O lines, a 4-channel 10-bit ADC, USI, and multiple timer/counters. The component is housed in an 8-lead SOIC package (S8S1) and utilizes tape and reel packaging.

Feature Summary

• AVR enhanced RISC architecture executing powerful instructions in a single clock cycle for efficient processing.
• Non-volatile memories including ISP Flash, EEPROM, and SRAM with programming lock capabilities for data security.
• Integrated peripheral features such as a 10-bit ADC, Universal Serial Interface (USI), and dual PWM channels.
• Supports multiple power-saving modes including Idle, Power-down, and ADC Noise Reduction.

Applications

• Low-power embedded control systems
• Battery-operated devices requiring extended runtime
• Industrial sensor interfaces
• Consumer electronics with limited pin counts

Procurement Notes

Verify the specific ordering code matches the required speed grade, voltage range, and temperature rating. Confirm the 'R' suffix indicates tape and reel packaging and the 'H' suffix denotes NiPdAu lead finish. Ensure compatibility with existing PCB footprints for the S8S1 package type before finalizing procurement orders.

Selection Notes

Select this variant for applications requiring operation down to 1.8 V with a 10 MHz maximum frequency. The SHR suffix specifies surface mount tape and reel packaging suitable for automated assembly. Consider the industrial temperature range and RoHS compliance when choosing this part for commercial or industrial deployments.

Part Context

This component belongs to the ATtiny25/45/85 family of 8-bit microcontrollers based on the AVR core. It shares architectural similarities with other members like the ATtiny45V and ATtiny85V but differs in memory capacity. The V-series designation indicates support for the lower 1.8 V operating voltage range compared to standard non-V variants.
