ATTINY26-16MQ

Overview

The ATTINY26-16MQ is an 8-bit AVR microcontroller featuring a 16 MHz RISC core, 2 KB Flash memory, 128 B EEPROM, and 128 B SRAM. It provides 16 programmable I/O lines within a 32-pad QFN/MLF package (5x5 mm). Key peripherals include an 11-channel 10-bit ADC with differential gain options, two 8-bit timers with PWM outputs, a Universal Serial Interface (USI), and an analog comparator. Operating voltage ranges from 4.5 V to 5.5 V.

Feature Summary

• High-performance 8-bit AVR architecture with up to 16 MIPS throughput at 16 MHz
• Integrated 10-bit ADC supporting single-ended and differential channels with programmable gain
• Dual 8-bit Timer/Counters with high-speed PWM outputs including non-overlapping inverted pins
• Universal Serial Interface (USI) enabling software-based TWI or SM-bus communication

Applications

• Battery chargers
• Lighting ballasts
• Low-end thermostats
• Fire detectors

Procurement Notes

Verify the specific ordering code matches the required speed grade and package variant. Confirm that the device operates within the specified 4.5 V to 5.5 V supply range for the standard ATtiny26 model. Ensure the MLF package bottom pad is soldered to ground as per datasheet requirements.

Selection Notes

Select this component for applications requiring low power consumption alongside moderate processing speed. The inclusion of differential ADC channels with programmable gain makes it suitable for precision sensor interfaces. Verify compatibility with existing SPI programming infrastructure for in-system programming.

Part Context

This part belongs to the ATtiny26 family, manufactured using high-density non-volatile memory technology. It combines an enhanced RISC CPU with Flash on a monolithic chip. The MLF package offers a compact surface-mount solution compared to traditional PDIP or SOIC variants.

Replacement Considerations

ATtiny26L-16MU: Lower voltage operation (2.7V - 5.5V) but limited to 8 MHz maximum frequency.
