ATTINY26-16PC

Overview

The ATTINY26-16PC is an 8-bit AVR microcontroller manufactured by Atmel (Microchip Technology). It features a 16 MHz operating frequency and utilizes a 20-pin PDIP package. The device includes 2 KB of in-system programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. Key peripherals include an 11-channel 10-bit ADC, two 8-bit timers/counters with PWM capabilities, and a universal serial interface supporting SPI and I2C protocols. It operates within a voltage range of 4.5 V to 5.5 V.

Feature Summary

• High-performance 8-bit AVR RISC architecture with single-cycle instruction execution
• Integrated 11-channel 10-bit analog-to-digital converter with programmable gain amplifier
• In-system programmable Flash memory for flexible code updates and protection
• Universal Serial Interface configurable as SPI, I2C, or three-wire bus

Applications

• Battery charger control systems
• Lighting ballast management
• Embedded sensor interfaces
• General-purpose industrial control

Procurement Notes

Verify the specific suffix 'PC' against official Microchip documentation to confirm the package type and temperature grade, as standard datasheets often list DIP20 variants without explicit suffix differentiation in summary tables. Confirm availability status, as older Atmel AVR models may be subject to lifecycle changes or obsolescence. Ensure the source document explicitly identifies the manufacturer as Atmel or its successor Microchip Technology to validate authenticity.

Selection Notes

Select this component when a low-pin-count solution is required for applications needing moderate processing speed and integrated analog conversion. The 20-pin PDIP format suits through-hole prototyping or legacy board designs. Consider the 4.5V minimum supply voltage constraint; if lower voltage operation is necessary, evaluate the ATtiny26L variant instead. Verify that the 2 KB Flash capacity meets application firmware requirements before finalizing the selection.

Part Context

This part belongs to the ATtiny26 family of enhanced AVR microcontrollers designed for cost-sensitive embedded applications. The series emphasizes low power consumption and high computational efficiency relative to its pin count. The ATtiny26 integrates essential peripherals like ADC and timers, reducing the need for external components in simple control loops.

Replacement Considerations

Publicly confirmed substitute part numbers include ATTINY26-16MI and ATTINY26-16MU. These alternatives share identical core specifications but differ in packaging, such as QFN formats. Verify pin compatibility and thermal characteristics when transitioning from the PDIP package to surface-mount alternatives.
