ATTINY26L-8PJ

Overview

The ATtiny26L-8PJ is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture, housed in a 20-pin PDIP package. It features 2K bytes of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device operates at speeds up to 8 MHz with a supply voltage range of 2.7V to 5.5V. Key peripherals include an 8-bit timer/counter, PWM outputs, a 10-bit ADC with multiple channels, and a universal serial interface.

Feature Summary

• High-performance and low-power 8-bit AVR RISC architecture
• In-system programmable non-volatile memory for Flash and EEPROM
• Integrated analog-to-digital converter with differential channels
• Programmable watchdog timer and multiple low-power modes

Applications

• Battery-powered consumer devices
• Simple industrial control systems
• Low-cost sensor interfaces
• Basic communication nodes

Procurement Notes

Verify the specific suffix PJ corresponds to the 20-pin PDIP package configuration. Confirm the speed grade matches the required operational frequency of 8 MHz. Ensure the voltage rating aligns with the 2.7V to 5.5V operating range specified for the L-series variant. Cross-reference the manufacturer's current datasheet for any updates regarding pinout or electrical characteristics.

Selection Notes

Select this component when a balance of moderate processing power and low energy consumption is required. The 8 MHz speed grade suits applications not demanding high-frequency clocking. Consider the available I/O lines and peripheral count against system requirements. Verify that the PDIP package fits the mechanical constraints of the target design.

Part Context

This part belongs to the ATtiny26L family, designed for cost-sensitive embedded applications. It shares architectural similarities with other AVR microcontrollers but offers a specific combination of memory and peripherals. The 'L' suffix denotes low-voltage operation capabilities compared to standard variants.

Replacement Considerations

Check for direct substitutes within the ATtiny26 series, such as the ATtiny26-8PU, noting differences in voltage ranges and maximum frequencies. Evaluate cross-family alternatives like the ATtiny25 or ATtiny45 if pin compatibility allows.
