Summary

2570NS–AVR–05/11

ATmega325/3250/645/6450

resulting architecture is more code efficient while achieving throughputs up to ten times faster

than conventional CISC microcontrollers.

The Atmel ATmega325/3250/645/6450 provides the following features: 32/64K bytes of In-Sys-

tem Programmable Flash with Read-While-Write capabilities, 1/2K bytes EEPROM, 2/4K byte

SRAM, 54/69 general purpose I/O lines, 32 general purpose working registers, a JTAG interface

for Boundary-scan, On-chip Debugging support and programming, three flexible Timer/Counters

with compare modes, internal and external interrupts, a serial programmable USART, Universal

Serial Interface with Start Condition Detector, an

8-channel,

10-bit ADC, a programmable

Watchdog Timer with internal Oscillator, an SPI serial port, and five software selectable power

saving modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI

port, and interrupt system to continue functioning. The Power-down mode saves the register

contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or

hardware reset. In Power-save mode, the asynchronous timer will continue to run, allowing the

user to maintain a timer base while the rest of the device is sleeping. The ADC Noise Reduction

mode stops the CPU and all I/O modules except asynchronous timer and ADC to minimize

switching noise during ADC conversions. In Standby mode, the crystal/resonator Oscillator is

running while the rest of the device is sleeping. This allows very fast start-up combined with low-

power consumption.

Atmel offers the QTouch

library for embedding capacitive touch buttons, sliders and wheels-

functionality into AVR microcontrollers. The patented charge-transfer signal acquisition

offersrobust sensing and includes fully debounced reporting of touch keys and includes Adjacent

KeySuppression

(AKS

™

) technology for unambiguous detection of key events. The easy-to-use

QTouch Suite toolchain allows you to explore, develop and debug your own touch applications.

The device is manufactured using Atmel’s high density non-volatile memory technology. The

On-chip In-System re-Programmable (ISP) Flash allows the program memory to be repro-

grammed In-System through an SPI serial interface, by a conventional non-volatile memory

programmer, or by an On-chip Boot program running on the AVR core. The Boot program can

use any interface to download the application program in the Application Flash memory. Soft-

ware in the Boot Flash section will continue to run while the Application Flash section is updated,

providing true Read-While-Write operation. By combining an

8-bit

RISC CPU with In-System

Self-Programmable Flash on a monolithic chip, the Atmel Atmel ATmega325/3250/645/6450 is a

powerful microcontroller that provides a highly flexible and cost effective solution to many

embedded control applications.

The Atmel ATmega325/3250/645/6450 is supported with a full suite of program and system

development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators,

In-Circuit Emulators, and Evaluation kits.
