ATTINY26-16SU

Overview

The ATTINY26-16SU is an 8-bit AVR microcontroller in a 20-lead SOIC package. It features 2 KB of In-System Programmable Flash, 128 Bytes of EEPROM, and 128 Bytes of SRAM. The device operates at frequencies up to 16 MHz with a supply voltage range of 4.5 V to 5.5 V. It includes 16 programmable I/O lines, an 11-channel 10-bit ADC, two 8-bit Timer/Counters, and a Universal Serial Interface.

Feature Summary

• High-performance RISC architecture achieving up to 16 MIPS throughput at 16 MHz
• Integrated high-precision 10-bit ADC with differential channels and programmable gain
• Dual 8-bit Timer/Counter modules supporting PWM outputs and non-overlapping inverted pins
• Universal Serial Interface (USI) for software implementation of TWI or SM-bus protocols

Applications

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

Procurement Notes

Verify the specific suffix 'SU' corresponds to the 20-lead Plastic Gull Wing Small Outline (SOIC) package as defined in the ordering information table. Confirm that the speed grade '16' indicates the 0 - 16 MHz operational range suitable for the 4.5 V to 5.5 V supply voltage requirement. Ensure the industrial temperature range (-40°C to +85°C) matches the application environment specifications.

Selection Notes

Select this component when a low-power 8-bit solution with integrated analog capabilities is required. The ATtiny26-16SU is appropriate for designs needing multiple ADC channels and flexible serial communication interfaces without dedicated hardware UARTs. Consider the 20-lead SOIC package for through-hole or surface-mount assembly constraints where pin count limits are strict.

Part Context

This part belongs to the ATtiny26 family, which utilizes Atmel's high-density non-volatile memory technology. The family combines an enhanced RISC 8-bit CPU with Flash on a monolithic chip. The ATtiny26 variant specifically supports higher clock speeds compared to the ATtiny26L, targeting applications requiring faster processing within the standard 5V logic voltage domain.

Replacement Considerations

ATtiny26-16PU (PDIP package), ATtiny26-16SUR (Tape & Reel SOIC package), ATtiny26-16MU (QFN/MLF package).
