ATTINY25V-10SI

Overview

The ATTINY25V-10SI is an 8-bit AVR microcontroller featuring 2 KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 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 a 4-channel 10-bit ADC, Universal Serial Interface (USI), two PWM channels, and six programmable I/O lines. It utilizes the Advanced RISC architecture for efficient processing and supports industrial temperature ranges from -40°C to 85°C.

Feature Summary

• Advanced RISC architecture executing most instructions in a single clock cycle
• In-system programmable non-volatile memory with high endurance
• Integrated analog-to-digital converter with multiple channel options
• Universal Serial Interface supporting standard communication protocols

Applications

• Industrial control systems requiring low power consumption
• Battery-powered embedded devices utilizing extended voltage ranges
• Sensor interface modules using integrated ADC capabilities
• General-purpose logic replacement in compact surface-mount designs

Procurement Notes

Verify the specific ordering code matches the required speed grade and package type. Confirm that the 'V' suffix indicates the 1.8V operational capability and the 'SI' suffix corresponds to the SOIC narrow package variant. Ensure compatibility with existing PCB footprints for the 8-lead Small Outline package before finalizing procurement orders.

Selection Notes

Select this component when a low-cost 8-bit controller with extensive I/O flexibility is needed. The 1.8V operating range makes it suitable for battery applications where standard 5V or 3.3V parts may not suffice. Consider the USI peripheral if dedicated SPI or I2C hardware is unavailable on alternative smaller packages within the same family.

Part Context

This device belongs to the ATtiny series of 8-bit microcontrollers based on the AVR enhanced RISC architecture. It shares core specifications with the ATtiny45 and ATtiny85 models, differing primarily in program memory capacity. The 'V' designation denotes the lower voltage operation range compared to standard variants, expanding its utility in energy-constrained environments.

Replacement Considerations

ATtiny25V-10SU serves as a direct pin-compatible alternative in the standard SOIC package.
