Overview

The ATTINY5-TSHR is a high-performance, low-power 8-bit AVR RISC-based microcontroller in a tiny 6-pin SOT-23 package. It features 512 bytes of flash and 32 bytes of internal SRAM, making it one of the smallest and most cost-effective solutions for simple control logic and signal processing.

Why Choose This Part

This MCU provides a significant footprint reduction using the SOT-23-6 package while maintaining 12MHz performance. It offers a highly efficient power profile, drawing as little as 0.2mA at 1.8V and 1MHz, which is ideal for battery-operated applications.

Applications

Signal Conditioning
Using the on-chip analog comparator or the 4-channel 8-bit ADC to monitor sensor thresholds in space-constrained designs.
Safety Interlocks
Implementing programmable watchdog timers and basic logic for power-sequencing or system-health monitoring.
Capacitive Touch
Leveraging QTouch library support to add simple touch buttons to small consumer devices.
PWM Generation
Generating simple pulse-width modulation signals for LED dimming or small motor control via its 16-bit timer.

Getting Started

Development is supported by Microchip Studio and the MPLAB X IDE using the XC8 compiler. Hardware programming requires a TPI (Tiny Programming Interface) compatible tool, such as the MPLAB PICkit 4 or the Atmel-ICE, as this part does not support standard ISP.
