ATTINY26-16MI

Overview

The ATTINY26-16MI is an 8-bit AVR microcontroller featuring a 16 MHz throughput, 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. The device operates at 4.5 V to 5.5 V and includes an 11-channel 10-bit ADC, two 8-bit timers with PWM outputs, a Universal Serial Interface (USI), and an analog comparator.

Feature Summary

• AVR enhanced RISC architecture with up to 16 MIPS throughput at 16 MHz
• Integrated 10-bit ADC with differential channels and programmable gain
• Dual 8-bit Timer/Counters with high-frequency PWM outputs
• Universal Serial Interface (USI) supporting TWI and SPI protocols

Applications

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

Procurement Notes

Verify the ordering suffix 'MI' corresponds to the 32-lead QFN/MLF package and Industrial temperature range (-40°C to +85°C). Confirm that the specific revision matches the required datasheet version for errata compliance regarding Analog Comparator delays.

Selection Notes

Select this component when a low-pin-count MCU requires integrated analog features like a 10-bit ADC and programmable gain amplifiers. The USI interface allows flexible software implementation of serial communication protocols without dedicated hardware peripherals.

Part Context

This part belongs to the ATtiny26 family, which combines high-density non-volatile memory with an enhanced RISC 8-bit CPU. The 'L' variant supports lower voltages (2.7V - 5.5V) and speeds up to 8 MHz, whereas the standard ATtiny26 operates from 4.5V to 5.5V with speeds up to 16 MHz.

FAQ

What is the function of the bottom pad in the QFN/MLF package?

The bottom pad under the QFN/MLF package should be soldered to ground.

How does the USI interface support communication?

The Universal Serial Interface enables efficient software implementation of TWI (Two-wire Serial Interface) or SM-bus interfaces.
