ATMEGA169PV-8MU Description

“An highly efficient microcontroller called the ATmega169P features an 8-bit low-power CMOS architecture that is based on the AVR improved RISC architecture. The powerful instructions in this microcontroller may execute in just one clock cycle, resulting in processing speeds of approximately 1 MIPS per MHz. This microcontroller is built to perform very well. This manual will go through the architecture, programming, and interfacing of the ATmega169P as well as its capabilities. This book will give you a thorough overview of the ATmega169P and how it can help you achieve optimal power consumption against processing speed, whether you’re an experienced engineer wanting to improve your designs or a novice looking to learn more about microcontrollers.”

An 8-bit Atmel® AVR® microcontroller with great performance and low power, the ATmega169PV-8MU offers several cutting-edge features and functions.

ATMEGA169PV-8MU Features

● Advanced RISC Architecture:

With its strong RISC architecture, the ATmega169PV-8MU can process up to 16 MIPS at 16 MHz by completing 130 instructions in a single clock cycle.

● Enduring power Memory Sections That Are Not Volatile:

The ATmega169PV-8MU includes a 1 KByte static random access memory (SRAM), a 512-byte EEPROM, and a 16 KByte self-programmable flash memory for storing programs. Data is guaranteed to remain intact for up to 20 years at 85°C and 100 years at 25°C, respectively, because of the chip’s high write/erase cycle count of 10,000 for flash and 100,000 for EEPROM.

● JTAG Interface:

The boundary-scan capabilities and comprehensive on-chip debug support of the ATmega169PV-8MU are made possible by its JTAG (IEEE standard. 1149.1 compliant) interface. Through the JTAG interface, flash, EEPROM, fuses, and lock bits can be programmed.

● Peripheral Features:

Among the peripheral features offered by the ATmega169PV-8MU are a 4-by-25-segment LCD driver, a 16-bit timer/counter, a real-time counter, four PWM channels, an 8-channel 10-bit ADC, a programmable serial USART, and a programmable watchdog timer.

● Special Microcontroller Features:

There are five different sleep modes and an external and internal interrupt source available on the ATmega169PV-8MU, in addition to a power-on reset and programmed brown-out detection.

● Speed Grade:

The ATmega169PV-8MU can function at speeds of 0-4 MHz at voltages between 1.8V and 5.5V, 0-8 MHz at voltages between 2.7V and 5.5V, and 0-16 MHz at voltages between 4.5V and 5.5V.

● Temperature Range:

The ATmega169PV-8MU works in temperatures ranging from -40 degrees Celsius to 85 degrees Celsius, making it ideal for manufacturing.

● Ultra-Low Power Consumption:

At 1 MHz and 1.8V, the ATmega169PV-8MU uses 330 A of power in active mode, while at 32 kHz and 1.8V, it uses 10 A (including the oscillator) and 25 A (including the oscillator and LCD). Power consumption in power-down mode is only 0.1 A at 1.8V, and in the power-save mode, it’s 0.6 A. (including 32 kHz RTC).

The ATmega169PV-8MU is a state-of-the-art microcontroller that excels in various uses thanks to its great performance and low power consumption.

Detailed Description

● Status Register

The result of the most recent arithmetic instruction is recorded in the Status Register. The data can be utilized to conduct conditional operations and modify the program’s flow accordingly. It is important to keep in mind that, as per the Instruction Set Reference, the Status Register is updated following each and every ALU operation. As a result, you won’t have to use the specialized compare instructions as often, making your code faster and smaller. When entering an interrupt routine, the Status Register is not saved and afterward restored automatically. Software is required to manage this.

● AVR Memories

The Data Memory and the Program Memory are the two primary memory areas in an AVR architecture. Aside from its ability to store information in RAM, the ATmega169P also has a memory that can store information in EEPROM. There is a consistent linearity throughout all three memory domains.

● Power Management and Sleep Modes

Sleep modes allow the program to power down the MCU’s unused subsystems. Users can adjust the AVR’s power consumption to meet the needs of any given application by selecting from several different sleep modes.

● Idle Mode

The SLEEP command puts the MCU into Idle mode by setting the SM2.0 bits to 000. This disables the CPU but does not disable the LCD controller, SPI, USART, analog comparator, ADC, USI, timers/counters, watchdog, or interrupt system.

When the MCU is idle, interrupts like the Timer Overflow and USART Transmit Complete interrupts, among others, might wake it up from sleep. If it is not necessary to be awakened by the analog comparator interrupt, turn off the analog comparator by setting the ACD bit in the analog comparator control and status register – ACSR. As a result, power usage during Idle times will be lowered. When switched to this mode, a conversion is initiated immediately if the ADC is active.

● ADC Noise Reduction Mode

The SLEEP instruction causes the MCU to enter ADC Noise Reduction mode when the SM2..0 bits are written to 001. This suspends CPU activity while other peripherals, such as the ADC, external interrupts, USI start condition detection, Timer/Counter2, LCD Controller, and Watchdog, continue to function normally (if enabled). During sleep mode, all but one of the clocks are disabled, though the others continue to run normally (clkI/O, clkCPU, and clkFLASH).

This reduces background noise for the ADC, allowing for more precise readings. When switched to this mode, a conversion is initiated immediately if the ADC is active. As well as the ADC Conversion Finished interrupt, the MCU can be roused from ADC Noise Reduction mode by the following: an external reset, a watchdog reset, a brown-out reset, an interrupt from the LCD controller, an interrupt from the USI upon startup, an interrupt from the Timer/Counter2, an interrupt from the SPM/EEPROM, an interrupt from the external level on INT0, or a pin change interrupt.

● Power-down Mode

By setting the SM2..0 bits to 010 with the SLEEP command, the MCU goes into Powerdown mode. With this setting, the external Oscillator is disabled while the USI start condition detector and the Watchdog remain active (if enabled).


Finally, the ATmega169PV-8MU is a high-performance and low-power microcontroller that provides a variety of capabilities to fulfill the requirements of diverse applications. This microcontroller can provide quick and effective processing thanks to its sophisticated RISC architecture, potent instructions, and high-endurance non-volatile memory. Therefore, the ATmega169PV-8MU is the best option if you’re looking for a versatile and affordable solution for your next project.
