ATTINY25-20SH

Overview

The ATTINY25-20SH is an 8-bit AVR microcontroller featuring a high-performance RISC architecture with 120 instructions, most executing in a single clock cycle. It integrates 2 KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device includes six programmable I/O lines, a 4-channel 10-bit ADC, two PWM channels, and a Universal Serial Interface (USI). Operating at speeds up to 20 MHz within a voltage range of 2.7 V to 5.5 V, it supports industrial temperature ranges and offers multiple power-saving modes.

Procurement Notes

Verify the ordering code suffix 'H' indicates a NiPdAu lead finish as specified in the datasheet. Confirm that the package type corresponds to the JEDEC SOIC standard for the specific variant. Ensure the selected speed grade matches the required operating frequency and supply voltage conditions defined in the official specification tables.

Selection Notes

Select this component when a compact 8-pin solution is required for applications needing 2 KB of program memory. Consider the NiPdAu lead finish if environmental resistance or specific soldering compatibility is necessary. Verify that the 20 MHz speed grade meets the processing requirements within the 2.7 V to 5.5 V operating voltage range.

Part Context

This part belongs to the ATtiny25/45/85 family of low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. The family shares core features such as the instruction set, peripheral modules, and memory organization, differing primarily in flash size and pin count configurations across the series variants.
