ATTINY10-MAHR

Overview

The ATTINY10-MAHR is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It features 1024 bytes of In-System Programmable Flash, 32 bytes of internal SRAM, and four programmable I/O lines. The device includes a 16-bit Timer/Counter with two PWM channels, an Analog Comparator, and a 4-channel 8-bit ADC. Operating voltage ranges from 1.8V to 5.5V. Speed grades include up to 4MHz at 1.8-5.5V, 8MHz at 2.7-5.5V, and 12MHz at 4.5-5.5V. It supports industrial (-40°C to 85°C) and extended (-40°C to 125°C) temperature ranges.

Feature Summary

• Advanced RISC Architecture with single clock cycle execution for high throughput
• Integrated Capacitive Touch Sensing support via QTouch Library
• Multiple software selectable power saving modes including Power-down and Idle
• On-chip Analog Comparator and Programmable Watchdog Timer

Applications

• Capacitive touch sensing interfaces
• Low power embedded control systems
• Battery operated sensor nodes

Procurement Notes

Verify the specific speed grade suffix (e.g., MAHR indicates 12MHz Industrial) against the required operating voltage and temperature range. Confirm package type matches design constraints. Ensure programming environment supports in-system programming at 5V as specified. Check for any errata regarding lock bit programming procedures before finalizing production designs.

Selection Notes

Select this component when minimal I/O count and ultra-low power consumption are critical. Compare with ATtiny4 if ADC functionality is not required. Consider the UDFN package dimensions for space-constrained layouts. Verify that the available timer and interrupt resources meet application timing requirements.

Part Context

This part belongs to the ATtiny4/5/9/10 family of 8-bit AVR microcontrollers. It shares the core architecture with ATtiny4, ATtiny5, and ATtiny9 but is distinguished by its 1024-byte Flash memory and integrated ADC capabilities. The family utilizes Atmel's high density Non-Volatile Memory technology.
