ATTINY10-TSHRA0

Overview

The ATTINY10-TSHRA0 is an 8-bit AVR microcontroller featuring 1024 bytes of In-System Programmable Flash and 32 bytes of SRAM. It includes a 4-channel, 8-bit Analog to Digital Converter (ADC) and an on-chip Analog Comparator. The device supports four programmable I/O lines and operates within a voltage range of 1.8V to 5.5V. Speed grades include up to 4 MHz at 1.8–5.5V, 8 MHz at 2.7–5.5V, and 12 MHz at 4.5–5.5V. It utilizes a 6-pin SOT-23 package.

Feature Summary

• Advanced RISC architecture with single-cycle execution for optimized power consumption versus processing speed.
• Integrated capacitive touch sensing support via QTouch library for one channel.
• Multiple low-power modes including Idle, ADC Noise Reduction, Power-down, and Standby.
• Built-in safety features such as a programmable watchdog timer and enhanced power-on reset circuit.

Applications

• Battery-powered consumer electronics requiring minimal footprint
• Simple capacitive touch interface implementations
• Low-speed data acquisition systems using the internal ADC

Procurement Notes

Verify that the specific suffix 'A0' aligns with the manufacturer's current ordering codes, as datasheets primarily list 'TSHR'. Confirm the industrial temperature range (-40°C to 85°C) matches your environmental requirements. Ensure programming equipment supports the required 5V ISP voltage level for in-system programming.

Selection Notes

Select this component when system design demands the smallest possible package size alongside basic analog capabilities. It is suitable for applications where code space exceeds 512 bytes but remains under 1024 bytes. Consider the ATtiny9 if ADC functionality is not required to reduce cost further.

Part Context

This part belongs to the ATtiny4/5/9/10 family, which shares a common core architecture and peripheral set. The ATtiny10 variant specifically distinguishes itself by offering 1024 bytes of Flash memory and integrated ADC channels, unlike the ATtiny4 or ATtiny9 variants.
