ATTINY26L-8PU 8-Bit AVR Microcontrollers IC PDIP-20
The ATtiny26L-8PU is a compact, low-power 8-bit microcontroller built around Atmel’s AVR enhanced RISC core. Its architecture emphasises code efficiency and fast instruction throughput so that many control tasks execute in a single clock cycle. With an on-chip Flash program memory and integrated SRAM and EEPROM, the device is intended for standalone embedded controllers where modest program size and low energy use matter.
Peripherals are grouped to support mixed analog/digital designs without large external circuitry: a multi-channel 10-bit ADC with selectable gains, two 8-bit timer/counters (one optimized for high frequency PWM), an analog comparator and a Universal Serial Interface for simple serial protocols. The combination of ADC channels, PWM outputs and comparator functions makes the chip suitable for sensing and closed-loop control duties while keeping board area and BOM small.
Power and clock options are flexible: an internal calibrated RC oscillator and selectable low-power sleep modes let designers trade responsiveness for battery life, while the device’s in-system programmable Flash and SPI programming support field updates and on-board debugging. The datasheet frames the ATtiny26L as a cost-effective, highly integrated MCU for small control tasks where simplicity, compactness and low power are required.
