8284FS–AVR–07/2014
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 Atmel 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 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 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 XTAL/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 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 the Atmel 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 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
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 control applications.
The ATmega169A/169PA/329A/329PA/3290A/3290PA/649A/649P/6490A/6490P AVR 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.

2.3 Pin descriptions
The following section describes the I/O-pin special functions.
2.3.1 VCC
Digital supply voltage.
2.3.2 GND
Ground.
2.3.3 Port A (PA7...PA0)
Port A is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port A output
buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port A pins that
are externally pulled low will source current if the pull-up resistors are activated. The Port A pins are tri-stated when
a reset condition becomes active, even if the clock is not running.
Port A also serves the functions of various special features of the Atmel
ATmega169A/169PA/329A/329PA/3290A/3290PA/649A/649P/6490A/6490P as listed on page 72.
2.3.4 Port B (PB7...PB0)
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output
buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port B pins that
are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when
a reset condition becomes active, even if the clock is not running.

2.3.15 AVCC
AVCC is the supply voltage pin for Port F and the A/D Converter. It should be externally connected to VCC, even if
the ADC is not used. If the ADC is used, it should be connected to VCC through a low-pass filter.
2.3.16 AREF
This is the analog reference pin for the A/D Converter.
2.3.17 LCDCAP
An external capacitor (typical > 470 nF) must be connected to the LCDCAP pin as shown in Figure 24-2, if the LCD
module is enabled and configured to use internal power. This capacitor acts as a reservoir for LCD power (VLCD). A
large capacitance reduces ripple on VLCD but increases the time until VLCD reaches its target value.

years at 85°C or 100 years at 25°C.
5. About code examples
This documentation contains simple code examples that briefly show how to use various parts of the device. These
code examples assume that the part specific header file is included before compilation. Be aware that not all C
compiler vendors include bit definitions in the header files and interrupt handling in C is compiler dependent.
Please confirm with the C compiler documentation for more details.
For I/O Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI” instructions must be
replaced with instructions that allow access to extended I/O. Typically “LDS” and “STS” combined with “SBRS”,
“SBRC”, “SBR”, and “CBR”.
6. Capacitive touch sensing
The Atmel® QTouch® Library provides a simple to use solution to realize touch sensitive interfaces on most Atmel
AVR® microcontrollers. The QTouch Library includes support for the QTouch and QMatrix® acquisition methods.
Touch sensing can be added to any application by linking the appropriate Atmel QTouch Library for the AVR
Microcontroller. This is done by using a simple set of APIs to define the touch channels and sensors, and then
calling the touch sensing API’s to retrieve the channel information and determine the touch sensor states.
The QTouch Library is FREE and downloadable from the Atmel website at the following location:
www.atmel.com/qtouchlibrary. For implementation details and other information, refer to the Atmel QTouch Library
User Guide - also available for download from the Atmel website.

8284FS–AVR–07/2014
Notes: 1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
should never be written.
2. I/O Registers within the address range 0x00 - 0x1F are directly bit-accessible using the SBI and CBI instructions. In these
registers, the value of single bits can be checked by using the SBIS and SBIC instructions.
3. Some of the Status Flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI
instructions will only operate on the specified bit, and can therefore be used on registers containing such Status Flags. The
CBI and SBI instructions work with registers 0x00 to 0x1F only.
4. When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When addressing I/O
Registers as data space using LD and ST instructions, 0x20 must be added to these addresses. The Atmel
ATmega169A/169PA/329A/329PA/3290A/3290PA/649A/649P/6490A/6490P is a complex microcontroller with more
peripheral units than can be supported within the 64 location reserved in Opcode for the IN and OUT instructions. For the
Extended I/O space from 0x60 - 0xFF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used.

•Interrupts may be lost when writing the timer registers in the asynchronous timer
•Using BOD disable will make the chip reset
1. Interrupts may be lost when writing the timer registers in the asynchronous timer
The interrupt will be lost if a timer register that is synchronous timer clock is written when the asynchronous
Timer/Counter register (TCNTx) is 0x00.
Problem Fix/ Workaround
Always check that the asynchronous Timer/Counter register neither have the value 0xFF nor 0x00 before writ-
ing to the asynchronous Timer Control Register (TCCRx), asynchronous Timer Counter Register (TCNTx), or
asynchronous Output Compare Register (OCRx).
2. Using BOD disable will make the chip reset
If the part enters sleep with the BOD turned off with the BOD disable option
enabled, a BOD reset will be generated at wakeup and the chip will reset.
Problem Fix/Workaround
Do not use BOD disable
