ATTINY25V-10SSHR

Overview

The ATTINY25V-10SSHR 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 interface, two PWM channels, and six programmable I/O lines. It utilizes the S8S1 package (8-lead, 0.150" wide JEDEC SOIC) with NiPdAu lead finish and tape & reel packaging.

Feature Summary

• AVR enhanced RISC architecture executing powerful instructions in a single clock cycle for efficient processing.
• Non-volatile memory including ISP Flash, EEPROM, and internal SRAM with programming lock capabilities.
• Integrated peripheral features such as a 10-bit ADC, USI, and dual high-frequency PWM outputs.
• Supports multiple low-power 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 count requirements

Procurement Notes

Verify the specific ordering suffix 'H' indicates NiPdAu lead finish and 'R' denotes tape & reel packaging. Confirm the S8S1 package dimensions match the design footprint. Ensure the industrial temperature range (-40°C to +85°C) aligns with environmental requirements. Cross-reference the datasheet revision for any errata related to EEPROM read operations at low voltages.

Selection Notes

Select this variant for applications requiring a 1.8 V minimum operating voltage and a narrow body SOIC package. The NiPdAu finish offers specific surface properties compared to matte tin options. Consider the 10 MHz speed grade relative to the 1.8 V to 5.5 V supply range. Evaluate the need for tape & reel handling versus tube packaging based on assembly line configuration.

Part Context

This component belongs to the ATtiny25/45/85 family of 8-bit AVR microcontrollers manufactured by Microchip Technology. It shares core architectural features with other members of the series, differing primarily in memory size and package availability. The 'V' suffix denotes the lower voltage operation capability down to 1.8 V.

Replacement Considerations

Compatible substitutes include ATTINY25V-10SSU (matte tin finish), ATTINY25V-10SSUR (matte tin, tape & reel), ATTINY25V-10SSH (NiPdAu, tube), and ATTINY25V-10SNR (narrow SOIC). Verify package compatibility and lead finish requirements when substituting.
