Atmel ATmega32/ATmega32L User Manual
The ATmega32 and ATmega32L are low‑power 8‑bit AVR microcontrollers featuring up to 32 KB of in‑system programmable Flash, 1 KB EEPROM, 2 KB SRAM, and a rich peripheral set including timers, PWM, ADC, USART, SPI and JTAG. They operate from 2.7 V to 5.5 V (ATmega32L) or 4.5 V to 5.5 V (ATmega32) and can deliver up to 16 MIPS at 16 MHz.
This manual covers the device’s pin‑out diagrams, detailed pin descriptions, core architecture, register set, status register, programming options, and example code. It also includes electrical specifications, power‑saving modes, and reference information for developers writing firmware for these microcontrollers.
