3D Model

The ATtiny26L has a high precision ADC with up to 11 single ended channels and 8 differential channels. Seven differential channels have an optional gain of 20x. Four out of the seven differential channels, which have the optional gain, can be used at the same time. ATtiny26L also has a high frequency 8-bit PWM module with two independent outputs. Two of the PWM outputs have inverted non-overlapping output pins ideal for synchronous rectification. The Universal Serial Interface of the ATtiny26L allows efficient software implementation of TWI (Two-wire Serial Interface) or SM-bus interface. These features allow for highly integrated battery charger and lighting ballast applications, low-end thermostats, and firedetectors, among other applications. By combining an enhanced RISC 8-bit CPU with Flash on a monolithic chip, the ATtiny26L is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications. The ATtiny26L AVR is supported with a full suite of program and system development tools including: Macro assemblers, program debugger/simulators, In-circuit emulators, and evaluation kits.

This article provides you with a basic overview of the ATTINY26L 8-bit Microcontroller, including its pin descriptions, features and specifications, etc., to help you quickly understand what ATTINY26L is.
