ATmega169A/PA/329A/PA/3290A/PA/649A/P/6490A/P
architecture is more code efficient while achieving throughputs up to ten times faster than con-
ventional CISC microcontrollers.
The ATmega169A/169PA/329A/329PA/3290A/3290PA/649A/649P/6490A/6490P 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, a complete On-chip LCD controller with internal contrast control,
three flexible Timer/Counters with compare modes, internal and external interrupts, a serial pro-
grammable 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 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 modules 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.

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 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 ATmega169A/169PA/329A/329PA/3290A/3290PA/649A/649P/6490A/6490P is a powerful
microcontroller that provides a highly flexible and cost effective solution to many embedded con-
trol applications.
The ATmega169A/169PA/329A/329PA/3290A/3290PA/649A/649P/6490A/6490P 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.
