Atmel ATmega64/ATmega64L Datasheet
The ATmega64 and ATmega64L are low‑power 8‑bit AVR microcontrollers featuring up to 64 KB of in‑system programmable Flash, 2 KB EEPROM, 4 KB SRAM, and 53 programmable I/O lines. They include multiple timers, PWM channels, a 10‑bit ADC, dual USARTs, SPI, JTAG, and extensive low‑power modes.
The document details the device architecture, pin‑out for TQFP/MLF packages, voltage ranges (2.7‑5.5 V for ATmega64L, 4.5‑5.5 V for ATmega64), speed grades (0‑8 MHz for ATmega64L, 0‑16 MHz for ATmega64), and compatibility with ATmega103. It also covers reset behavior, programming interfaces, and peripheral functions.
