8018IS–AVR–11/06

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 con-

ventional CISC microcontrollers.

The ATmega169P 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

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 com-

bined 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 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 ATmega169P is a powerful microcontroller that provides a highly flex-

ible and cost effective solution to many embedded control applications.

The ATmega169P 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

2.2.1

VCC

Digital supply voltage.

2.2.2

2.2.3

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 ATmega169P as listed on

”Alternate Functions of Port A” on page 72.

2.2.4

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.

Port B has better driving capabilities than the other ports.

Port B also serves the functions of various special features of the ATmega169P as listed on

”Alternate Functions of Port B” on page 73.

2.2.5

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 ATmega169P as listed on ”Alternate

Functions of Port C” on page 76.

2.2.6

2.2.7

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 ATmega169P as listed on

”Alternate Functions of Port E” on page 80.

2.2.8

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 buffers have sym-

metrical 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, see ”Alternate Functions of Port F” on

page 82

2.2.9

Port G (PG5:PG0)

Port G is a 6-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 ATmega169P as listed on

page 84.

2.2.10

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 9-1 on page

46. Shorter pulses are not guaranteed to generate a reset.

2.2.11

Output from the inverting Oscillator amplifier.

AVCC is the supply voltage pin for Port F and the A/D Converter. It should be externally con-

nected to V_CC, even if the ADC is not used. If the ADC is used, it should be connected to V_CC

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 Fig-

ure 22-2 on page 234. This capacitor acts as a reservoir for LCD power (V_LCD). A large

capacitance reduces ripple on V_LCDbut increases the time until V_LCDreaches 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 ATmega169P is a com-

plex 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.
