ATTINY25V-10SSH

Overview

The ATTINY25V-10SSH is an 8-bit AVR microcontroller from Microchip Technology, featuring a 10 MHz speed grade and operating within a 1.8V to 5.5V supply voltage range. It utilizes the industrial temperature range (-40°C to +85°C) and is housed in an 8-lead SOIC (S8S1) package with NiPdAu lead finish. The device integrates 2KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of internal SRAM.

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 serial programming and debugging
• Multiple software selectable power saving modes including Idle and Power-down

Applications

• Low power embedded control systems
• Battery operated devices requiring extended runtime
• Industrial monitoring applications within specified temperature ranges
• Simple sensor interface nodes using ADC and I/O lines

Procurement Notes

Verify the specific ordering suffix 'H' indicates a NiPdAu lead finish rather than standard matte tin. Confirm the package designation matches the S8S1 JEDEC SOIC footprint requirements for your PCB layout. Ensure the design supports the 1.8V minimum supply voltage characteristic of the V-series variant.

Selection Notes

Select this component when a low pin count solution is required alongside sufficient flash memory for moderate firmware complexity. The V-series designation ensures compatibility with lower voltage rails down to 1.8V compared to standard variants. Consider the NiPdAu lead finish if specific solderability or environmental resistance criteria are mandated by the assembly process.

Part Context

This part belongs to the ATtiny25/45/85 family of 8-bit CMOS microcontrollers based on the AVR core. It shares architectural similarities with the ATtiny45 and ATtiny85, differing primarily in non-volatile memory capacities. The device is manufactured using high density non-volatile memory technology compatible with standard AVR development tools.

Replacement Considerations

ATtiny25V-10SSU serves as a direct functional substitute with identical specifications but utilizes a matte tin lead finish instead of NiPdAu.
