ATTINY26L-8PU

Overview

The ATTINY26L-8PU is an 8-bit AVR microcontroller featuring a 20-lead PDIP package. It includes 2 KB of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device supports a maximum clock frequency of 8 MHz and operates within a voltage range of 2.7 V to 5.5 V. It provides 16 programmable I/O lines, two 8-bit timers/counters, a 10-bit ADC with 11 single-ended channels, and a Universal Serial Interface.

Feature Summary

• High-performance RISC architecture executing most instructions in a single clock cycle
• Integrated high-resolution analog-to-digital converter with differential input gain stages
• Multiple power-saving modes including idle, noise reduction, and power-down
• In-system programmable via SPI port for program memory and data security

Applications

• Battery charger systems
• Lighting ballast applications
• Low-end thermostats
• Fire detectors

Procurement Notes

Verify the specific ordering code matches the required speed grade and package type. Confirm that the industrial temperature range (-40°C to +85°C) aligns with the target application environment. Ensure the 20-lead PDIP form factor fits the designated PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when low power consumption is critical alongside moderate processing requirements. The ATtiny26L variant is suitable for designs requiring operation down to 2.7 V, unlike the standard ATtiny26 which requires a minimum of 4.5 V. Consider the available I/O count and ADC channels against system interface needs.

Part Context

This device belongs to the ATtiny26(L) family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. It combines a high-density non-volatile memory technology with an 8-bit CPU on a monolithic chip. The series offers flexible solutions for embedded control applications through its rich instruction set and peripheral integration.

Replacement Considerations

ATtiny26-16PU serves as a higher-speed alternative within the same package family.
