2. Overview

The ATmega169P is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By execut-

ing powerful instructions in a single clock cycle, the ATmega169P achieves throughputs approaching 1 MIPS per MHz

allowing the system designer to optimize power consumption versus processing speed.

7735B–AVR–12/07

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.

2.2

Automotive Quality Grade

The ATmega169P have been developed and manufactured according to the most stringent

requirements of the international standard ISO-TS-16949. This data sheet contains limit values

extracted from the results of extensive characterization (Temperature and Voltage). The quality

and reliability of the ATmega169P have been verified during regular product qualification as per

AEC-Q100 grade 3.

As indicated in the ordering information paragraph, the products are available in industrial tem-

perature grades, but with equivalent automotive quality and reliability objectives. Different

temperature identifiers have been defined as listed in Table 2-1.

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.
