Description

ATmega168P-20AU is an 8-bit AVR microcontroller from Atmel (Microchip) in a 32-pin TQFP package (AU). It uses the AVR RISC core, runs up to 20 MHz, and is suited for embedded control with a good balance of memory and peripherals.
Key specs:
- Memory: 16 KB Flash, 1 KB SRAM, 512 B EEPROM
- I/O and peripherals: about 23 general-purpose I/O lines, 8-channel 10-bit ADC, SPI, I2C (TWI), USART, 3 timers with PWM
- Other features: watchdog timer, analog comparator, brown-out detector; in-system programming via SPI
- Power and speed: operates 1.8–5.5 V (at 20 MHz, typically 4.5–5.5 V)
- Development: supported by Atmel Studio / AVR-GCC; bootloaders enable Arduino-style development on compatible boards
Typical applications: small to medium embedded controllers, sensors, hobbyist projects, or devices needing moderate memory and a rich peripheral set.

Features

ATmega168P-20AU is an 8‑bit AVR microcontroller (16/32-pin package) with the following key features:
- CPU: AVR RISC, up to 20 MHz operation (max 20 MIPS)
- Memory: 16 KB Flash, 1 KB SRAM, 512 B EEPROM
- Clock/Power: operating from 1.8–5.5 V; supports internal RC and external clock
- Peripherals:
- Timers: three timers (Timer0 and Timer2 8-bit with PWM; Timer1 16-bit)
- ADC: 8-channel, 10-bit ADC
- Analog comparator
- Serial interfaces: USART/UART, SPI, I2C (TWI)
- I/O: numerous I/O lines on the 32-pin package
- Interrupts: external interrupts and pin-change interrupts
- Power management: sleep modes, brown-out detection, reset options
- Programming/Debug: In-System Programming (ISP); bootloader support
- Package: AU suffix denotes the TQFP/32-pin package
(Concise feature set; specs may vary slightly by package and revision.)

Package

ATmega168P-20AU is supplied in a 32-pin Thin Quad Flat Pack (TQFP) surface-mount package.

Pinout

- Pin count: 32 pins (32-pin TQFP package, AU).
- Function: ATmega168P is an 8-bit AVR microcontroller with built-in flash (16 KB), EEPROM (1 KB), RAM (1 KB), and peripherals (USART, SPI, I2C/TWI, ADC, timers/PWM). It operates up to 20 MHz and provides general-purpose I/O for embedded control.

Manufacturer

Manufacturer: Atmel Corporation (now part of Microchip Technology Inc.).
What kind of company: A semiconductor company that designs and manufactures microcontrollers (notably AVR devices), memory, and other embedded ICs. Atmel was acquired by Microchip Technology in 2016.

Application

ATmega168P-20AU is a low-power, 8-bit AVR MCU suitable for:
- General embedded control in consumer electronics and appliances
- Home/building automation and remote sensing
- Data logging and instrumentation
- Sensor interfacing using ADC, UART, SPI, I2C
- Small robotics and motor control (PWM, timers)
- Battery-powered portable devices
- Educational/prototyping and hobby projects
Note: not automotive-grade or safety-critical.

Equivalent

Direct equivalents (same silicon, different packaging):
- ATmega168P-PU (DIP28)
- ATmega168P-AU (32‑pin TQFP)
The same silicon is also available in other package formats under ATmega168P. For a memory headroom upgrade in the same family, consider ATmega328P (32 KB flash in similar packages).
