ATTINY26-16MU

Overview

The ATTINY26-16MU is an 8-bit AVR microcontroller featuring a 32-lead QFN/MLF package. It operates at speeds up to 16 MHz with a supply voltage range of 4.5V to 5.5V. The device includes 2K bytes of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It provides 16 programmable I/O lines, an 11-channel 10-bit ADC, two 8-bit timers/counters, and a Universal Serial Interface (USI).

Feature Summary

• AVR enhanced RISC architecture with 32 general-purpose working registers for efficient code execution.
• Integrated high-precision 10-bit Analog-to-Digital Converter with multiple single-ended and differential input channels.
• Dual 8-bit Timer/Counter modules supporting PWM outputs and separate output compare registers.
• Universal Serial Interface enabling software implementation of TWI or SM-bus communication protocols.

Applications

• Battery charger systems requiring integrated control and monitoring.
• Lighting ballast applications utilizing non-overlapping PWM outputs.
• Low-end thermostats and firedetectors needing analog sensing capabilities.

Procurement Notes

Verify the specific ordering suffix 'MU' corresponds to the 32-lead MLF/QFN package variant. Confirm that the speed grade '16' matches the required 16 MHz operational frequency and the associated 4.5V to 5.5V power supply constraints. Ensure the industrial temperature range aligns with system requirements.

Selection Notes

Select this component when a compact 32-lead surface-mount package is required alongside robust analog features. The ATtiny26-16MU is suitable for designs needing multiple ADC channels and flexible serial communication via USI without dedicated hardware UARTs. Consider the 4.5V minimum operating voltage for power rail compatibility.

Part Context

This part belongs to the ATtiny26 family of low-power CMOS 8-bit microcontrollers based on the AVR architecture. The family offers a balance of processing performance and peripheral integration within a small footprint. The ATtiny26 series supports both standard and low-voltage variants, differentiated by speed grades and operating voltage ranges.
