ATTINY25V-10SSU

Overview

The ATTINY25V-10SSU 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, USI for serial communication, two 8-bit timers/counters, and six programmable I/O lines. It utilizes the S8S1 package (JEDEC SOIC) and supports industrial temperature ranges.

Feature Summary

• AVR enhanced RISC architecture executing most instructions in a single clock cycle
• In-system programmable via SPI port for program memory reprogramming
• On-chip debug system supporting debugWIRE functionality
• Multiple software selectable power saving modes including Idle and Power-down

Applications

• Embedded control systems requiring low power consumption
• Battery-powered applications utilizing extended voltage operation
• Industrial environments necessitating robust reset circuits and brown-out detection

Procurement Notes

Verify that the ordering suffix 'SSU' corresponds to the specific JEDEC SOIC package width and matte tin lead finish as defined in the manufacturer's documentation. Confirm the speed grade matches the required operational frequency for the target supply voltage. Ensure the component meets the necessary environmental standards for the intended deployment location.

Selection Notes

Select this variant when a 1.8 V minimum operating voltage is required alongside a 10 MHz performance ceiling. The S8S1 package offers a narrower body profile compared to standard SOIC options. Consider the internal calibrated oscillator if external crystal resources are constrained or cost-sensitive.

Part Context

This component belongs to the ATtiny25/V family within the broader AVR microcontroller portfolio. It shares architectural similarities with the ATtiny45 and ATtiny85, differing primarily in memory capacity. The 'V' designation indicates support for lower voltage operation down to 1.8 V, distinguishing it from the standard ATtiny25 series.

Replacement Considerations

ATtiny25V-10SU serves as a direct alternative offering identical specifications but utilizing the EIAJ SOIC package format instead of the JEDEC standard.
