This document describes the features and characteristics of a high-performance, low-power AVR® 8-bit microcontroller, including advanced RISC architecture, nonvolatile program and data memories, peripheral features, and special microcontroller features.
The ATmega8535 is a low‑power 8‑bit AVR microcontroller featuring up to 8 MIPS at 16 MHz, 8 KB of in‑system self‑programmable Flash, 512 B EEPROM, 512 B SRAM, three timer/counters, a 10‑bit ADC with differential inputs, and multiple serial interfaces. It operates from 2.7 V to 5.5 V (ATmega8535L) or 4.5 V to 5.5 V (ATmega8535) and supports speed grades up to 16 MHz.
The document includes pin‑out diagrams for PDIP, TQFP, PLCC and QFN packages, detailed port and pin descriptions, a complete register summary, and information on compatibility with the AT90S8535. Additional resources such as development tools, application notes, and code examples are listed on Atmel’s website.
