概述

Description

ATmega168PA-AN is an AVR 8-bit microcontroller from Atmel (Microchip). It uses the AVR RISC core and is part of the megaAVR family, suitable for small embedded control tasks.
Key features
- Memory: 16 KB flash, 1 KB SRAM, 512 B EEPROM
- I/O: about 23 general-purpose I/O pins
- Peripherals: 8-channel, 10-bit ADC; three timers (Timer0/2 8-bit with PWM; Timer1 16-bit with PWM)
- Communications: USART, SPI, and I2C (TWI)
- PWM: up to six PWM outputs
- Power and sleep: Brown-out detector, Watchdog Timer, multiple sleep modes
- Clock: up to 20 MHz; operating voltage roughly 1.8–5.5 V (speed/voltage dependent)
- Programming: in-system programming via SPI (ISP); bootloader support (e.g., AVR/Arduino-compatible)
Note: The -AN suffix denotes a specific package/temperature variant. Check the datasheet for exact packaging and temperature range. Typical uses include compact embedded controllers, sensor interfaces, and small control apps.

Features

ATmega168PA-AN features (concise):
- 8-bit AVR RISC CPU with ~1 clock cycle per instruction
- Memory: 16 KB flash program memory; 1 KB EEPROM; 1 KB SRAM
- Clock: up to 20 MHz operation (Vcc dependent)
- I/O: about 23 general-purpose I/O lines
- Analogue: 8-channel, 10-bit ADC; on-chip analog comparator
- Timers: Timer0 (8-bit), Timer1 (16-bit), Timer2 (8-bit) with PWM
- Communications: USART (UART), SPI, I2C (TWI)
- Interrupts: multiple vectored interrupts (ext interrupts available)
- Power and sleep: brown-out detection; multiple sleep modes (Idle, ADC Noise Reduction, Power-down, Power-save, Standby)
- Programming/debug: In-System Programming (ISP); bootloader support; on-chip debugging options (e.g., debugWIRE on supported variants)
- Packaging: available in common 28-pin packages (DIP/TQFP/QFN variants)
- Other: on-chip oscillator options (external crystal or internal RC); low power consumption options
Note: exact packaging and temperature grade may vary by package/suffix.

Package

ATMEGA168PA-AN comes in a 28-pin TQFP (Thin Quad Flat Pack) surface-mount package.

Pinout

- Pin count: 32-pin package (ATmega168PA in 32-pin TQFP/QFN, typical).
- Function: 8-bit AVR microcontroller with 16 KB Flash, 1 KB EEPROM, 1 KB SRAM; 23 I/O pins; 8-channel 10-bit ADC; USART/UART, SPI, TWI/I2C; three timers (two 8-bit, one 16-bit); watchdog and external interrupts; operates at 1.8–5.5V, up to 16 MHz.

Manufacturer

- Manufacturer: Microchip Technology Inc. (the AVR line was originally made by Atmel; Atmel was acquired by Microchip in 2016, so ATmega168PA-AN is now produced under Microchip).
- Company type: Microchip is a global semiconductor company that designs and manufactures microcontrollers, memory, analog and mixed-signal ICs, and related software and services.

Application

ATmega168PA-AN is a general‑purpose 8‑bit AVR MCU for low‑cost embedded designs with moderate I/O and ADC. Common application areas include:
- Consumer electronics (remote controls, keyboards, toys)
- Home automation and metering
- Portable instruments and data loggers
- Sensor interfacing and data acquisition
- Small motor control and PWM
- Education and prototyping (Arduino‑like boards)
Features enabling these: 16 KB flash, 1 KB RAM, 1 KB EEPROM, 8‑channel 10‑bit ADC, timers, UART/SPI/I2C, and low‑power sleep modes.

Equivalent

Closest equivalents are other members of the AVR ATmega168 family:
- ATmega168P, ATmega168A, ATmega168 (same 16 KB flash, 1 KB RAM)
- For higher memory, ATmega328P (32 KB flash) is the common upgrade
All share the same AVR core and peripherals; choose the matching package variant (DIP, TQFP, etc.) as needed.
