ATmega165A/PA/325A/PA/3250A/PA/645A/P/6450A/P

The ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P provides the

following features: 16K/32K/64K bytes of In-System Programmable Flash with Read-While-Write

capabilities, 512/1K/2K bytes EEPROM, 1K/2K/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 Condi-

tion 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 continues 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 mod-

ules 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 sleep-

ing. 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 offers

robust sensing and includes fully debounced reporting of touch keys and includes Adjacent Key

Suppression

(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 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 pro-

gram running on the AVR core. The Boot program can use any interface to download the

application program in the Application 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 devise is a powerful microcontroller that provides a highly flexible and

cost effective solution to many embedded control applications.

The ATmega165A/165PA/325A/325PA/3250A/3250PA/645A/645P/6450A/6450P AVR is sup-

ported with a full suite of program and system development tools including: C Compilers, Macro

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