Description

ATmega649A-MU is an 8‑bit AVR microcontroller from Atmel (now Microchip) in the megaAVR family. It uses the AVR RISC core and can run up to about 20 MHz, delivering efficient, low‑power control for embedded apps.
Package: MU denotes a 40‑pin surface‑mount package (typical 40‑pin QFN/TQFP style).
Memory and peripherals: on‑chip flash memory (64 KB variants are common for the 649 line), plus EEPROM and SRAM. It provides a rich peripheral set: multiple I/O lines, timers (including 16‑bit), PWM outputs, a 10‑bit ADC, USART, SPI, and I2C/TWI, plus watchdog, brown‑out detection, and various sleep modes.
Development: supports in‑system programming via ISP; compatible with standard AVR toolchains (AVR-GCC, Atmel Studio, etc.).
Typical use: general embedded control, sensors, motor/actuator control, and consumer electronics.
Note: exact memory sizes and peripherals depend on the specific -MU variant; consult the datasheet for precise specs.

Features

ATmega649A-MU is a 8/16-bit AVR microcontroller in a 40-pin MU package with:
- Memory: 64 KB Flash, 4 KB EEPROM, 4 KB SRAM
- CPU speed: up to 16 MHz (at 4.5–5.5V; lower voltages allow lower max freq)
- I/O: ~32 programmable I/O pins
