ATmega329/3290/649/6490

The AVR core combines a rich instruction set with 32 general purpose working registers.

All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing

two independent registers to be accessed in one single instruction executed in one clock

cycle. The resulting architecture is more code efficient while achieving throughputs up to

ten times faster than conventional CISC microcontrollers.

The ATmega329/3290/649/6490 provides the following features: 32/64K bytes of In-

System 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 regis-

ters, a JTAG interface for Boundary-scan, On-chip Debugging support and

programming, a complete On-chip LCD controller with internal contrast control, 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 con-

tinue 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 and the LCD controller continues to run,

allowing the user to maintain a timer base and operate the LCD display while the rest of

the device is sleeping. The ADC Noise Reduction mode stops the CPU and all I/O mod-

ules except asynchronous timer, LCD controller 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.

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

reprogrammed 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 Applica-

tion Flash memory. Software 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 ATmega329/3290/649/6490 is a powerful microcontroller that provides a

highly flexible and cost effective solution to many embedded control applications.

The ATmega329/3290/649/6490 AVR is supported with a full suite of program and sys-

tem development tools including: C Compilers, Macro Assemblers, Program

Debugger/Simulators, In-Circuit Emulators, and Evaluation kits.
