ATTINY5-MAH

Overview

The ATTINY5-MAH is an 8-bit microcontroller based on the AVR enhanced RISC architecture, manufactured by Microchip Technology. It features 512 bytes of in-system programmable Flash memory and 32 bytes of internal SRAM. The device includes a four-channel, 8-bit Analog to Digital Converter (ADC) and one 16-bit Timer/Counter with two PWM channels. It operates within a supply voltage range of 1.8V to 5.5V and supports speed grades up to 12MHz at 4.5V to 5.5V. The component is housed in an 8-pad UDFN package.

Feature Summary

• Supports QTouch library for capacitive touch sensing applications
• Includes an internal calibrated oscillator and programmable watchdog timer
• Features low power consumption with multiple selectable sleep modes

Applications

• Capacitive touch sensing interfaces

• Battery-operated devices requiring extended data retention

Procurement Notes

Verify the specific speed grade and temperature rating required for your application against the ordering information table. Confirm that the 8MA4 package type matches your PCB footprint requirements. Ensure compatibility with your programming voltage constraints, as in-system programming may require specific voltage levels depending on the selected speed grade.

Selection Notes

Select this component if your design requires integrated analog-to-digital conversion capabilities alongside minimal I/O lines. Consider the ATtiny4 variant if ADC functionality is unnecessary, or the ATtiny9/ATtiny10 variants if higher program memory capacity is needed. Evaluate the available speed grades relative to your target operating voltage to ensure optimal performance and power efficiency.
