ATmega169
The large center pad underneath the QFN/MLF packages is made of metal and internally
connected to GND. It should be soldered or glued to the board to ensure good mechanical stability. If the center pad is left unconnected, the package might loosen from the
board.
Typical values contained in this datasheet are based on simulations and characterization of other AVR microcontrollers manufactured on the same process technology. Min
and Max values will be available after the device is characterized.

2514PS–AVR–07/06
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 ATmega169 provides the following features: 16K bytes of In-System Programmable
Flash with Read-While-Write capabilities, 512 bytes EEPROM, 1K byte SRAM,
53 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 step-up voltage, 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 Powerdown 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.
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 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 Atmel ATmega169 is
a powerful microcontroller that provides a highly flexible and cost effective solution to
many embedded control applications.
The ATmega169 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.

Pin Descriptions
VCC
Digital supply voltage.
GND
Ground.
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 ATmega169 as listed
on page 62.
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.
Port B has better driving capabilities than the other ports.
Port B also serves the functions of various special features of the ATmega169 as listed
on page 63.
Port C (PC7..PC0)
Port C is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each
bit). The Port C output buffers have symmetrical drive characteristics with both high sink
and source capability. As inputs, Port C pins that are externally pulled low will source
current if the pull-up resistors are activated. The Port C pins are tri-stated when a reset
condition becomes active, even if the clock is not running.
Port C also serves the functions of special features of the ATmega169 as listed on page
66.
Port D (PD7..PD0)
Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each
bit). The Port D output buffers have symmetrical drive characteristics with both high sink
and source capability. As inputs, Port D pins that are externally pulled low will source
current if the pull-up resistors are activated. The Port D pins are tri-stated when a reset
condition becomes active, even if the clock is not running.
Port D also serves the functions of various special features of the ATmega169 as listed
on page 68.
Port E (PE7..PE0)
Port E is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each
bit). The Port E output buffers have symmetrical drive characteristics with both high sink
and source capability. As inputs, Port E pins that are externally pulled low will source
current if the pull-up resistors are activated. The Port E pins are tri-stated when a reset
condition becomes active, even if the clock is not running.
Port E also serves the functions of various special features of the ATmega169 as listed
on page 70.
Port F (PF7..PF0)
Port F serves as the analog inputs to the A/D Converter.
Port F also serves as an 8-bit bi-directional I/O port, if the A/D Converter is not used.
Port pins can provide internal pull-up resistors (selected for each bit). The Port F output
5
2514PS–AVR–07/06
buffers have symmetrical drive characteristics with both high sink and source capability.
As inputs, Port F pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port F pins are tri-stated when a reset condition becomes
active, even if the clock is not running. If the JTAG interface is enabled, the pull-up resistors on pins PF7(TDI), PF5(TMS), and PF4(TCK) will be activated even if a reset
occurs.
Port F also serves the functions of the JTAG interface.
Port G (PG4..PG0)
Port G is a 5-bit bi-directional I/O port with internal pull-up resistors (selected for each
bit). The Port G output buffers have symmetrical drive characteristics with both high sink
and source capability. As inputs, Port G pins that are externally pulled low will source
current if the pull-up resistors are activated. The Port G pins are tri-stated when a reset
condition becomes active, even if the clock is not running.
Port G also serves the functions of various special features of the ATmega169 as listed
on page 70.
RESET
Reset input. A low level on this pin for longer than the minimum pulse length will generate a reset, even if the clock is not running. The minimum pulse length is given in Table
16 on page 38. Shorter pulses are not guaranteed to generate a reset.
XTAL1
Input to the inverting Oscillator amplifier and input to the internal clock operating circuit.
XTAL2
Output from the inverting Oscillator amplifier.
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.
AREF
This is the analog reference pin for the A/D Converter.
LCDCAP
An external capacitor (typical > 470 nF) must be connected to the LCDCAP pin as
shown in Figure 98. 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.

Note:
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 ATmega169 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.

Errata
ATmega169 Rev E
• Interrupts may be lost when writing the timer registers in the asynchronous timer
1. Interrupts may be lost when writing the timer registers in the asynchronous
timer
If one of the timer registers which is synchronized to the asynchronous timer2 clock
is written in the cycle before a overflow interrupt occurs, the interrupt may be lost.
Problem Fix/Workaround
Always check that the Timer2 Timer/Counter register, TCNT2, does not have the
value 0xFF before writing the Timer2 Control Register, TCCR2, or Output Compare
Register, OCR2.
ATmega169 Rev D
• Interrupts may be lost when writing the timer registers in the asynchronous timer
• High serial resistance in the glass can result in dim segments on the LCD
• IDCODE masks data from TDI input
3. Interrupts may be lost when writing the timer registers in the asynchronous
timer
If one of the timer registers which is synchronized to the asynchronous timer2 clock
is written in the cycle before a overflow interrupt occurs, the interrupt may be lost.
Problem Fix/Workaround
Always check that the Timer2 Timer/Counter register, TCNT2, does not have the
value 0xFF before writing the Timer2 Control Register, TCCR2, or Output Compare
Register, OCR2.
2. High serial resistance in the glass can result in dim segments on the LCD
Some display types with high serial resistance (>20 kΩ) inside the glass can result
in dim segments on the LCD
Problem Fix/Workaround
Add a 1 nF (0.47 - 1.5 nF) capacitor between each common pin and ground.
1. IDCODE masks data from TDI input
The JTAG instruction IDCODE is not working correctly. Data to succeeding devices
are replaced by all-ones during Update-DR.
Problem Fix / Workaround
–
If ATmega169 is the only device in the scan chain, the problem is not visible.
–
Select the Device ID Register of the ATmega169 by issuing the IDCODE
instruction or by entering the Test-Logic-Reset state of the TAP controller to
read out the contents of its Device ID Register and possibly data from
succeeding devices of the scan chain. Issue the BYPASS instruction to the
ATmega169 while reading the Device ID Registers of preceding devices of
the boundary scan chain.
–
If the Device IDs of all devices in the boundary scan chain must be captured
simultaneously, the ATmega169 must be the first device in the chain.

6. Interrupts may be lost when writing the timer registers in the asynchronous
timer
If one of the timer registers which is synchronized to the asynchronous timer2 clock
is written in the cycle before a overflow interrupt occurs, the interrupt may be lost.
Problem Fix/Workaround
Always check that the Timer2 Timer/Counter register, TCNT2, does not have the
value 0xFF before writing the Timer2 Control Register, TCCR2, or Output Compare
Register, OCR2.
5. High Current Consumption In Power Down when JTAGEN is Programmed
The input buffer on TDO (PF6) is always enabled and the pull-up is always disabled
when JTAG is programmed. This can leave the output floating.
Problem Fix/Workaround
Add external pull-up to PF6.
Unprogram the JTAGEN Fuse before shipping out the end product.
4. LCD Contrast Control
The contrast control is not working properly when using synchronous clock (chip
clock) to obtain an LCD clock, and the chip clock is 125 kHz or faster.
Problem Fix/Workaround
Use a low chip clock frequency (32 kHz) or apply an external voltage to the LCDCAP pin.
3. Some Data Combinations Can Result in Dim Segments on the LCD
All segments connected to a common plane might be dimmed (lower contrast) when
a certain combination of data is displayed.
Problem Fix/Workaround
Default waveform: If there are any unused segment pins, loading one of these with a
1 nF capacitor and always write ‘0’ to this segment eliminates the problem.
Low power waveform: Add a 1 nF capacitor to each common pin.
2. LCD Current Consumption
In an interval where VCC is within the range VLCD -0.2V to VLCD + 0.4V, the LCD
current consumption is up to three times higher than expected. This will only be an
issue in Power-save mode with the LCD running as the LCD current is negligible
compared to the overall power consumption in all other modes of operation.
Problem Fix/Workaround
No known workaround.

8. Interrupts may be lost when writing the timer registers in the asynchronous
timer
If one of the timer registers which is synchronized to the asynchronous timer2 clock
is written in the cycle before a overflow interrupt occurs, the interrupt may be lost.
Problem Fix/Workaround
Always check that the Timer2 Timer/Counter register, TCNT2, does not have the
value 0xFF before writing the Timer2 Control Register, TCCR2, or Output Compare
Register, OCR2.
7. Internal Oscillator Runs at 4 MHz
The Internal Oscillator runs at 4 MHz instead of the specified 8 MHz. Therefore, all
Flash/EEPROM programming times are twice as long as specified. This includes
Chip Erase, Byte programming, Page programming, Fuse programming, Lock bit
programming, EEPROM write from the CPU, and Flash Self-Programming.
For this reason, rev-B samples are shipped with the CKDIV8 Fuse unprogrammed.
Problem Fix/Workaround
If 8 MHz operation is required, apply an external clock (this will be fixed in rev. C).
6. LCD Contrast Voltage is not Correct
The LCD contrast voltage between 1.8V and 3.1V is incorrect. When the VCC is
between 1.8V and 3.1V, the LCD contrast voltage drops approx. 0.5V. The current
consumption in this interval is higher than expected.
Problem Fix/Workaround
Contrast will be wrong, but display will still be readable, can be partly compensated
for using the contrast control register (this will be fixed in rev. C).
5. External Oscillator is Non-functional
The external oscillator does not run with the setup described in the datasheet.
Problem Fix/Workaround
Use other clock source (this will be fixed in rev. C).
19
2514PS–AVR–07/06
Alternative Problem Fix/Workaround
Adding a pull-down on XTAL1 will start the Oscillator.
4. USART
Writing TXEN to zero during transmission causes the transmission to suddenly stop.
The datasheet description tells that the transmission should complete before stopping the USART when TXEN is written to zero.
Problem Fix/Workaround
Ensure that the transmission is complete before writing TXEN to zero (this will be
fixed in rev. C).
3. ADC Measures with Lower Accuracy than Specified
The ADC does not work as intended. There is a positive offset in the result.
Problem Fix/Workaround
This will be fixed in rev. C.
2. Serial downloading
When entering Serial Programming mode the second byte will not echo back as
described in the Serial Programming algorithm.
Problem Fix/Workaround
Check if the third byte echoes back to ensure that the device is in Programming
mode (this will be fixed in rev. C).
