概要

Description

ATmega168-20MU is an 8‑bit AVR microcontroller from Atmel (Microchip) in a 32‑pin package, running up to 20 MHz.
Key specs:
- Memory: 16 KB flash, 1 KB SRAM, 512 B EEPROM.
- I/O: about 22 general-purpose I/O pins (Port A/B/C).
- Peripherals: 8‑channel 10‑bit ADC, three timers (8/16‑bit) with PWM, SPI, I2C (TWI), USART, analog comparator, watchdog timer.
- Features: in‑system programming via SPI, bootloader support, multiple power‑saving modes.
- Voltage and speed: 20 MHz operation typically requires ~4.5–5.5 V; lower speeds acceptable at 1.8–5.5 V.
- Architecture: Harvard, RISC with a compact, fast instruction set and 32 general-purpose registers.
Applications:
- Small embedded controllers, sensor data acquisition, motor control, hobby projects.
Development:
- Supported by AVR-GCC toolchain and Atmel Studio (Microchip Studio). Similar in spirit to Arduino-family MCUs (but with more direct AVR setup options).

Applications: general-purpose embedded control and low-power projects.

Package

ATmega168-20MU comes in a 28-pin SOIC (surface-mount) package.

Pinout

- Pin count: 28 pins (MU package, i.e., 28‑pin SOIC).
- Function: ATmega168 is an 8‑bit AVR microcontroller with up to 20 MHz operation, 16 KB Flash, 1 KB SRAM, 512 B EEPROM. Peripherals include three timers (0/1/2), 8‑channel 10‑bit ADC, USART, SPI, I2C/TWI, PWM outputs, watchdog timer, external interrupts, and I/O ports B/C/D (plus VCC, GND, AVCC, AREF, RESET).

Manufacturer

- Manufacturer: Atmel Corporation (now part of Microchip Technology after an acquisition).
- What kind of company: A semiconductor company that designs and manufactures microcontrollers and other embedded processing products (e.g., AVR MCUs, memory, touch solutions) for embedded systems.

Application

ATmega168-20MU is a low‑power 8‑bit AVR MCU with 16 KB flash, 1 KB RAM, 512 B EEPROM, 8‑ch 10‑bit ADC, timers, PWM, UART/SPI/I2C, and sleep modes. Suitable applications:
- Embedded control in consumer electronics (appliances, toys)
- Sensor data acquisition and data logging
- Home automation and remote sensing
- Robotics and motor/control applications
- Battery-powered portable devices and wearables
- Industrial instrumentation and small automation
- Automotive body electronics (sensors/displays)
