ATTINY26-16PU

Overview

The ATtiny26-16PU is an 8-bit AVR microcontroller featuring a 16 MHz RISC architecture with up to 16 MIPS throughput. It integrates 2 KB of In-System Programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device includes a 10-bit ADC with 11 single-ended channels, two 8-bit Timer/Counters with PWM outputs, and a Universal Serial Interface. It operates within a 4.5 V to 5.5 V supply range and provides 16 programmable I/O lines in a 20-lead PDIP package.

Feature Summary

• High-performance 8-bit AVR core executing most instructions in a single clock cycle
• Integrated non-volatile memory including ISP Flash, EEPROM, and internal SRAM
• Versatile peripheral set comprising dual 8-bit timers, high-speed PWM, and USI
• Precision analog subsystem with 10-bit ADC supporting differential inputs and gain stages

Applications

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

Procurement Notes

Verify the specific speed grade suffix (16) matches the required operational frequency of 16 MHz. Confirm the power supply voltage range aligns with the 4.5 V to 5.5 V specification for the standard ATtiny26 variant. Ensure the 20-lead PDIP package type corresponds to the design requirements. Check for RoHS compliance status if environmental regulations apply to the manufacturing process.

Selection Notes

Select this component when a cost-effective solution with moderate processing speed and integrated analog capabilities is required. The 16 MHz speed grade suits applications needing efficient code execution without complex external components. Consider the 20-pin PDIP package for through-hole assembly needs. Evaluate the available I/O lines and timer resources against the system interface requirements before finalizing the choice.

Part Context

This device belongs to the ATtiny26 family of low-power CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. The family offers flexibility through various package options and speed grades. The ATtiny26-16PU specifically denotes the industrial temperature range version operating at 16 MHz with a 4.5 V to 5.5 V supply requirement.

Replacement Considerations

ATtiny26L-16PU is not a valid substitute as the L variant supports a lower voltage range and maximum speed of 8 MHz.
