ATTINY25V-10SU

Overview

The ATTINY25V-10SU 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 within a voltage range of 1.8V to 5.5V with a maximum clock frequency of 10 MHz. The device includes six programmable I/O lines, a 4-channel 10-bit ADC, USI, two PWM channels, and an internal calibrated oscillator. It is housed in an 8-lead SOIC package.

Feature Summary

• AVR enhanced RISC architecture executing most instructions in a single clock cycle
• In-system programmable non-volatile memory for program and data storage
• Integrated Universal Serial Interface (USI) supporting SPI and TWI protocols
• Four-channel 10-bit analog-to-digital converter with selectable gain

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications operating across wide temperature ranges
• Sensor interface circuits utilizing the integrated ADC
• General-purpose digital logic replacement in compact designs

Procurement Notes

Verify that the specific ordering code matches the required speed grade and package variant. Confirm RoHS compliance status and lead finish specifications against project requirements. Ensure the intended operating voltage aligns with the V-series designation capabilities. Cross-reference datasheet errata regarding EEPROM read reliability at low frequencies.

Selection Notes

Select this component when a balance of processing speed and minimal power usage is critical. The V-series designation supports operation down to 1.8V, suitable for extended battery life. Consider the 10 MHz speed grade if higher throughput is needed compared to lower-speed variants. Evaluate package constraints as the SOIC form factor suits surface mount assembly processes.

Part Context

This device belongs to the ATtiny25/45/85 family of 8-bit microcontrollers based on the AVR core. The 'V' suffix indicates support for a wider supply voltage range starting at 1.8V. The '10' denotes the 10 MHz speed grade. The 'SU' identifies the specific 8-lead SOIC package configuration used in this part number.

Replacement Considerations

ATtiny25V-10SSU: Identical electrical specifications but utilizes a narrow SOIC package.
