What is ATTINY85-10SH used for?
The ATTINY85-10SH is popular in space-constrained designs such as wearable health monitors, USB HID accessories, and smart sensor nodes where an 8-bit core at up to 10 MHz is sufficient. Its 10-bit ADC and PWM outputs make it ideal for LED dimming, motor speed control, and simple data-acquisition tasks within battery-powered gadgets. The 8-pin SOIC package fits single-sided PCBs used in hobbyist projects and low-volume embedded production.

Frequently Asked Questions
How much on-chip memory does the ATTINY85-10SH provide, and how does that compare to the ATtiny45?
The ATTINY85-10SH contains 8 KB of Flash program memory, 512 bytes of SRAM, and 512 bytes of EEPROM. Compared to the ATtiny45, it doubles the Flash from 4 KB to 8 KB, allowing more complex firmware while retaining the same 8-pin SOIC footprint and pin-compatible layout, making it a drop-in upgrade for tightly coupled designs.
What ADC resolution and how many analog input channels does the ATTINY85-10SH support for sensor interfacing?
The ATTINY85-10SH features a 10-bit ADC with up to 4 single-ended input channels, delivering 1024 steps of resolution across the supply reference voltage. This suits temperature sensing, light sensing via photoresistors, and battery voltage monitoring in portable designs operating from 2.7V to 5.5V supplies.
For a USB accessory project, can the ATTINY85-10SH handle bit-banged USB at 10 MHz, and what is the clock source?
The ATTINY85-10SH can run bit-banged V-USB at 16.5 MHz using its internal PLL clock, or at exactly 12 MHz with crystal calibration, enabling low-speed USB HID device firmware. The internal oscillator reaches 8 MHz without a crystal, simplifying the BOM to just 2 decoupling capacitors and the chip itself in a standard 8-pin SOIC layout.
